CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to U.S. Application Ser. No. 61/008,153, filed on Dec. 17, 2007 and U.S. Application Ser. No. 61/025,017, filed on Jan. 31, 2008. The disclosures of the prior applications are considered part of (and are incorporated by reference in) the disclosure of this application. 
    
    
     BACKGROUND 
     The membrane type (MT)-matrix metalloproteinases (MMPs) constitute a sub-group of membrane-anchored MMPs that are major mediators of pericellular proteolysis and physiological activators of pro-MMP-2. MT-MMPs activate the zymogenic form of MMP-2 (pro-MMP-2 or pro-gelatinase A). MMP-2, in turn, can activate pro-MMP-9. The MT-MMPs comprise six members of plasma-tethered MMPs, which include four type I transmembrane enzymes (MMP-14, -15, -16, and -24) and two glycosylphosphatidylinositol-anchored enzymes (MMP-17 and -25). In addition to being potent extracellular matrix (ECM)-degrading enzymes, the type I transmembrane MT-MMPs can also initiate a cascade of zymogen activation on the cell surface. 
     MMPs are extensively studied in cancer and inflammation, and are well-validated in preclinical studies. Existing treatments for cancer, such as chemotherapy and radiotherapy improve the quality of life with no life-prolonging benefits and have significant side effects. Other treatments, such as MMP inhibitors, are being developed and further refined, and may work most effectively in cancers where certain MMPs are being expressed. 
     Patient stratification allows healthcare providers to assess the risk/benefit ratio of a given treatment and to predict what patients may best respond to a certain course of treatment. In general, the higher the risk of a particular disease, the better the risk/benefit ratio. Relative risk reduction by a given treatment is often similar across subgroups divided by sex, age, blood pressure etc.; however, if the absolute risk is low it may not be worth taking a treatment with serious side effects. Patient stratification is also important in assessing the cost effectiveness of treatment for a given set of patients. 
     SUMMARY 
     Provided are compositions and methods for quantifying the expression or activity of MMP-14 and other biomarkers of cancer, for example, osteotropic cancer, breast cancer, lung cancer, colon cancer or prostate cancer, which may be used diagnostically (e.g., to identify patients who have cancer, or a particular subclass of cancer) and prognostically (e.g., to identify patients who are likely to develop cancer or respond well to a particular therapeutic for treating cancer). Kits for detecting MMP-14 and other biomarkers and for the practice of the methods incorporating such detection are also described herein. 
     Specifically, in certain embodiments, provided are methods of utilizing expression of and/or expression ratios of any two of MMP-14, MMP-2 and MMP-9 in tumors and other cancer cells in order to stratify patients and identify those who would benefit from MMP-14 inhibitor treatment. For example, patients possessing tumors which express both MMP-14 and MMP-2 may be candidates for MMP-14 inhibitor treatment, and patients with tumors expressing MMP-14 and not MMP-2 may also benefit from MMP-14 inhibitor treatment. In another example, those patients with a high MMP-14/low MMP-9 expression ratio may benefit from MMP-14 inhibitor treatment. Further, by evaluating expression of MMP-14 and other MMP biomarkers (e.g., in a sample from a patient), patients can be diagnosed and potentially be stratified into groupings with different prognoses or drug responses. In some embodiments, “Low” and “High” refer to the intensity of immunohistochemistry staining for MMP-14 and MMP-9 expression in a carcinoma. For example, staining levels that are substantially the same as background levels of staining or about 10%, about 20%, about 30%, or about 40% greater than background levels of staining can be considered to be low levels; and staining levels that are about 2, about 3, about 4 fold or greater than background levels of staining can be considered to be high levels. As another example, in some embodiments, when the ratio of MMP-14/MMP-9 is &gt;1, there is more MMP-14 expression than MMP-9 expression and is considered to bea favorable indicator of MMP-14 binding protein (e.g., DX-2400) responsiveness in preclinical models and subjects, e.g., subjects with cancer. In this embodiment, these subjects would benefit from and/or are good candidates for (e.g., would be selected for) treatment with an MMP-14 binding protein. In some embodiments, when the ratio is &lt;1, MMP-9 expression is higher than MMP-14 expression, and that could be an indication of a non-responsive or low responsive tumor, e.g., in a subject with a tumor. In these embodiments, a subject with a ratio of &lt;1 would not be selected for and/or would not benefit from treatment with an MMP-14 binding protein. Expression levels, e.g., levels of staining can be quantified, e.g., as described herein. 
     Compositions and kits for the practice of these methods are also described herein. These embodiments of the present invention, other embodiments, and their features and characteristics will be apparent from the description, drawings, and claims that follow.

     DETAILED DESCRIPTION 
     For convenience, before further description of the present invention, certain terms employed in the specification, examples and appended claims are defined here. 
     The singular forms “a”, “an”, and “the” include plural references unless the context clearly dictates otherwise. 
     The term “agonist”, as used herein, is meant to refer to an agent that mimics or up-regulates (e.g., potentiates or supplements) the bioactivity of a protein. An agonist can be a wild-type protein or derivative thereof having at least one bioactivity of the wild-type protein. An agonist can also be a compound that upregulates expression of a gene or which increases at least one bioactivity of a protein. An agonist can also be a compound which increases the interaction of a polypeptide with another molecule, e.g., a target peptide or nucleic acid. 
     “Antagonist” as used herein is meant to refer to an agent that downregulates (e.g., suppresses or inhibits) at least one bioactivity of a protein. An antagonist can be a compound which inhibits or decreases the interaction between a protein and another molecule, e.g., a target peptide or enzyme substrate. An antagonist can also be a compound that downregulates expression of a gene or which reduces the amount of expressed protein present. 
     The term “antibody” refers to a protein that includes at least one immunoglobulin variable domain or immunoglobulin variable domain sequence. For example, an antibody can include a heavy (H) chain variable region (abbreviated herein as VH), and a light (L) chain variable region (abbreviated herein as VL). In another example, an antibody includes two heavy (H) chain variable regions and two light (L) chain variable regions. The term “antibody” encompasses antigen-binding fragments of antibodies (e.g., single chain antibodies, Fab and sFab fragments, F(ab′) 2 , Fd fragments, Fv fragments, scFv, and domain antibodies (dAb) fragments (de Wildt et al., Eur J. Immunol. 1996; 26(3):629-39)) as well as complete antibodies. An antibody can have the structural features of IgA, IgG, IgE, IgD, IgM (as well as subtypes thereof). Antibodies may be from any source, but primate (human and non-human primate) and primatized are preferred. 
     The VH and VL regions can be further subdivided into regions of hypervariability, termed “complementarity determining regions” (“CDR”), interspersed with regions that are more conserved, termed “framework regions” (“FR”). The extent of the framework regions and CDRs has been precisely defined (see, Kabat, E. A., et al. (1991)  Sequences of Proteins of Immunological Interest, Fifth Edition , U.S. Department of Health and Human Services, NIH Publication No. 91-3242, and Chothia, C. et al. (1987) J. Mol. Biol. 196:901-917, see also www.hgmp.mrc.ac.uk). Kabat definitions are used herein. Each VH and VL is typically composed of three CDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4. 
     The VH or VL chain of the antibody can further include all or part of a heavy or light chain constant region, to thereby form a heavy or light immunoglobulin chain, respectively. In one embodiment, the antibody is a tetramer of two heavy immunoglobulin chains and two light immunoglobulin chains, wherein the heavy and light immunoglobulin chains are inter-connected by, e.g., disulfide bonds. In IgGs, the heavy chain constant region includes three immunoglobulin domains, CH1, CH2 and CH3. The light chain constant region includes a CL domain. The variable region of the heavy and light chains contains a binding domain that interacts with an antigen. The constant regions of the antibodies typically mediate the binding of the antibody to host tissues or factors, including various cells of the immune system (e.g., effector cells) and the first component (Clq) of the classical complement system. The light chains of the immunoglobulin may be of types kappa or lambda. In one embodiment, the antibody is glycosylated. An antibody can be functional for antibody-dependent cytotoxicity and/or complement-mediated cytotoxicity. 
     One or more regions of an antibody can be human or effectively human. For example, one or more of the variable regions can be human or effectively human. For example, one or more of the CDRs can be human, e.g., HC CDR1, HC CDR2, HC CDR3, LC CDR1, LC CDR2, and LC CDR3. Each of the light chain CDRs can be human. HC CDR3 can be human. One or more of the framework regions can be human, e.g., FR1, FR2, FR3, and FR4 of the HC or LC. For example, the Fc region can be human. In one embodiment, all the framework regions are human, e.g., derived from a human somatic cell, e.g., a hematopoietic cell that produces immunoglobulins or a non-hematopoietic cell. In one embodiment, the human sequences are germline sequences, e.g., encoded by a germline nucleic acid. In one embodiment, the framework (FR) residues of a selected Fab can be converted to the amino-acid type of the corresponding residue in the most similar primate germline gene, especially the human germline gene. One or more of the constant regions can be human or effectively human. For example, at least 70, 75, 80, 85, 90, 92, 95, 98, or 100% of an immunoglobulin variable domain, the constant region, the constant domains (CH1, CH2, CH3, CL1), or the entire antibody can be human or effectively human. 
     All or part of an antibody can be encoded by an immunoglobulin gene or a segment thereof. Exemplary human immunoglobulin genes include the kappa, lambda, alpha (IgA1 and IgA2), gamma (IgG1, IgG2, IgG3, IgG4), delta, epsilon and mu constant region genes, as well as the many immunoglobulin variable region genes. Full-length immunoglobulin “light chains” (about 25 KDa or about 214 amino acids) are encoded by a variable region gene at the NH2-terminus (about 110 amino acids) and a kappa or lambda constant region gene at the COOH—terminus. Full-length immunoglobulin “heavy chains” (about 50 KDa or about 446 amino acids), are similarly encoded by a variable region gene (about 116 amino acids) and one of the other aforementioned constant region genes, e.g., gamma (encoding about 330 amino acids). The length of human HC varies considerably because HC CDR3 varies from about 3 amino-acid residues to over 35 amino-acid residues. 
     The term “binding” refers to an association, which may be a stable association, between two molecules, e.g., between a polypeptide of the invention and a binding partner, due to, for example, electrostatic, hydrophobic, ionic and/or hydrogen-bond interactions under physiological conditions. 
     The term “binding protein” refers to a protein or polypeptide that can interact with a target molecule. This term is used interchangeably with “ligand.” An “MMP-14 binding protein” refers to a protein that can interact with MMP-14, and includes, in particular, proteins that preferentially interact with and/or inhibit MMP-14. For example, the MMP-14 binding protein may be an antibody. 
     “Biological activity” or “bioactivity” or “activity” or “biological function”, which are used interchangeably, refer to an effector or antigenic function that is directly or indirectly performed by a polypeptide (whether in its native or denatured conformation), or by any subsequence thereof. Biological activities include binding to polypeptides, binding to other proteins or molecules, activity as a DNA binding protein, as a transcription regulator, ability to bind damaged DNA, etc. A bioactivity may be modulated by directly affecting the subject polypeptide. Alternatively, a bioactivity may be altered by modulating the level of the polypeptide, such as by modulating expression of the corresponding gene. 
     The term “biological sample”, as used herein, refers to a sample obtained from an organism or from components (e.g., cells) of an organism. The sample may be of any biological tissue or fluid. Frequently the sample will be a “clinical sample” which is a sample derived from a patient. Such samples include, but are not limited to, sputum, blood, blood cells (e.g., white cells), tissue or fine needle biopsy samples, urine, peritoneal fluid, and pleural fluid, or cells therefrom. Biological samples may also include sections of tissues such as frozen sections taken for histological purposes. 
     The term “cancer” is meant to refer to an abnormal cell or cells, or a mass of tissue. The growth of these cells or tissues exceeds and is uncoordinated with that of the normal tissues or cells, and persists in the same excessive manner after cessation of the stimuli which evoked the change. These neoplastic tissues or cells show a lack of structural organization and coordination relative to normal tissues or cells which may result in a mass of tissues or cells which can be either benign or malignant. As used herein, cancer includes any neoplasm. This includes, but is not limited to, melanoma, adenocarcinoma, malignant glioma, prostatic carcinoma, kidney carcinoma, bladder carcinoma, pancreatic carcinoma, thyroid carcinoma, lung carcinoma, colon carcinoma, rectal carcinoma, brain carcinoma, liver carcinoma, breast carcinoma, ovary carcinoma, bone cancer, and the like. 
     A “combinatorial library” or “library” is a plurality of compounds, which may be termed “members,” synthesized or otherwise prepared from one or more starting materials by employing either the same or different reactants or reaction conditions at each reaction in the library. In general, the members of any library show at least some structural diversity, which often results in chemical diversity. A library may have anywhere from two different members to about 10 8  members or more. In certain embodiments, libraries of the present invention have more than about 12, 50 and 90 members. In certain embodiments of the present invention, the starting materials and certain of the reactants are the same, and chemical diversity in such libraries is achieved by varying at least one of the reactants or reaction conditions during the preparation of the library. Combinatorial libraries of the present invention may be prepared in solution or on the solid phase. 
     The term “diagnosing” includes prognosing and staging a disease or disorder. 
     “Gene” or “recombinant gene” refers to a nucleic acid molecule comprising an open reading frame and including at least one exon and (optionally) an intron sequence. “Intron” refers to a DNA sequence present in a given gene which is spliced out during mRNA maturation. 
     The terms “label” or “labeled” refer to incorporation or attachment, optionally covalently or non-covalently, of a detectable marker into a molecule, such as a polypeptide and especially an antibody. Various methods of labeling polypeptides are known in the art and may be used. Examples of labels for polypeptides include, but are not limited to, the following: radioisotopes, fluorescent labels, heavy atoms, enzymatic labels or reporter genes, chemiluminescent groups, biotinyl groups, predetermined polypeptide epitopes recognized by a secondary reporter (e.g., leucine zipper pair sequences, binding sites for secondary antibodies, metal binding domains, epitope tags). Examples and use of such labels are described in more detail below. In some embodiments, labels are attached by spacer arms of various lengths to reduce potential steric hindrance. Particular examples of labels which may be used under the invention include fluorescein, rhodamine, dansyl, umbelliferone, Texas red, luminol, NADPH, alpha-galactosidase, beta-galactosidase and horseradish peroxidase. 
     The “level of expression of a gene in a cell” or “gene expression level” refers to the level of mRNA, as well as pre-mRNA nascent transcript(s), transcript processing intermediates, mature mRNA(s) and degradation products, encoded by the gene in the cell. 
     The term “modulation”, when used in reference to a functional property or biological activity or process (e.g., enzyme activity or receptor binding), refers to the capacity to either up regulate (e.g., activate or stimulate), down regulate (e.g., inhibit or suppress) or otherwise change a quality of such property, activity or process. In certain instances, such regulation may be contingent on the occurrence of a specific event, such as activation of a signal transduction pathway, and/or may be manifest only in particular cell types. 
     The term “modulator” refers to a polypeptide, nucleic acid, macromolecule, complex, molecule, small molecule, compound, species or the like (naturally-occurring or non-naturally-occurring), or an extract made from biological materials such as bacteria, plants, fungi, or animal cells or tissues, that may be capable of causing modulation. Modulators may be evaluated for potential activity as inhibitors or activators (directly or indirectly) of a functional property, biological activity or process, or combination of them, (e.g., agonist, partial antagonist, partial agonist, inverse agonist, antagonist, anti-microbial agents, inhibitors of microbial infection or proliferation, and the like) by inclusion in assays. In such assays, many modulators may be screened at one time. The activity of a modulator may be known, unknown or partially known. 
     As used herein, the term “nucleic acid” refers to polynucleotides such as deoxyribonucleic acid (DNA), and, where appropriate, ribonucleic acid (RNA). The term should also be understood to include, as equivalents, analogs of either RNA or DNA made from nucleotide analogs, and, as applicable to the embodiment being described, single (sense or antisense) and double-stranded polynucleotides. ESTs, chromosomes, cDNAs, mRNAs, and rRNAs are representative examples of molecules that may be referred to as nucleic acids. 
     The term “osteotropic cancer” refers to metastatic cancer of the bone, i.e., a secondary cancer present in bone that originates from a primary cancer, such as that of the breast, lung, or prostate. 
     A “patient”, “subject” or “host” to be treated by the subject method may mean either a human or non-human animal. 
     “Protein”, “polypeptide” and “peptide” are used interchangeably herein when referring to a chain of amino acids prepared by protein synthesis techniques or to a gene product, e.g., as may be encoded by a coding sequence. By “gene product” it is meant a molecule that is produced as a result of transcription of a gene. Gene products include RNA molecules transcribed from a gene, as well as proteins translated from such transcripts. 
     “Recombinant protein”, “heterologous protein” and “exogenous protein” are used interchangeably to refer to a polypeptide which is produced by recombinant DNA techniques, wherein generally, DNA encoding the polypeptide is inserted into a suitable expression vector which is in turn used to transform a host cell to produce the heterologous protein. That is, the polypeptide is expressed from a heterologous nucleic acid. 
     “Small molecule” as used herein, is meant to refer to a composition, which has a molecular weight of less than about 5 kD and most preferably less than about 4 kD. Small molecules can be nucleic acids, peptides, polypeptides, peptidomimetics, carbohydrates, lipids or other organic (carbon-containing) or inorganic molecules. Many pharmaceutical companies have extensive libraries of chemical and/or biological mixtures, often fungal, bacterial, or algal extracts, which can be screened with any of the assays of the invention to identify compounds that modulate a bioactivity. 
     “Stage classification” or “staging” is generally, classification of cancer by progression observable by the naked eye, and TNM classification (tumor-node-metastasis staging) is widely used internationally. The “stage classification” used in the present invention corresponds to the TNM classification (“Rinsho, Byori, Genpatsusei Kangan Toriatsukaikiyaku (Clinical and Pathological Codes for Handling Primary Liver Cancer)”: 22 p. Nihon Kangangaku Kenkyukai (Liver Cancer Study Group of Japan) edition (3rd revised edition), Kanehara Shuppan, 1992). 
     “Therapeutic agent” or “therapeutic” refers to an agent capable of having a desired biological effect on a host. Chemotherapeutic and genotoxic agents are examples of therapeutic agents that are generally known to be chemical in origin, as opposed to biological, or cause a therapeutic effect by a particular mechanism of action, respectively. Examples of therapeutic agents of biological origin include growth factors, hormones, and cytokines. A variety of therapeutic agents are known in the art and may be identified by their effects. Certain therapeutic agents are capable of regulating red cell proliferation and differentiation. Examples include chemotherapeutic nucleotides, drugs, hormones, non-specific (non-antibody) proteins, oligonucleotides (e.g., antisense oligonucleotides that bind to a target nucleic acid sequence (e.g., mRNA sequence)), peptides, and peptidomimetics. 
     The term “therapeutically effective amount” refers to that amount of a modulator, drug or other molecule which is sufficient to effect treatment when administered to a subject in need of such treatment. The therapeutically effective amount will vary depending upon the subject and disease condition being treated, the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art. 
     The term “treating” as used herein is intended to encompass curing as well as ameliorating at least one symptom of any condition or disease. 
     MMP-14, MMP-2 and MMP-9 Biomarkers 
     Without wishing to be bound by theory, according to preferred embodiments of this disclosure, a cancer to be targeted with an anti-MMP-14 treatment (e.g., treatment with an MMP-14 binding protein, e.g., DX-2400) expresses MMP-14. In preferred embodiments, the MMP-14 is active. Thus, reagents, e.g., proteins (e.g., antibodies) that specifically bind the active form of MMP-14, e.g., DX-2400 (which binds to the catalytic domain of MMP-14) are suitable reagents to practice the methods described herein. In other embodiments, the total levels of MMP-14 (e.g., inactive and active MMP-14) are measured. As described herein, in a tumor model using cells which do not express MMP-14, the tumor xenograft of such cells did not respond to DX-2400 treatment. In contrast, a tumor xenograft model using cells that express MMP-14 did respond to DX-2400 treatment. 
     According to another preferred embodiment, without being bound by theory, in determining responsiveness to anti-MMP-14 treatment (e.g., treatment with an MMP-14 binding protein, e.g., DX-2400), the levels of MMP-9 (e.g., active MMP-9) are determined. In preferred embodiments, low to no levels of active MMP-9 indicate that the tumor will be responsive to anti-MMP-14 treatment. For example, MMP-9 activity levels can be determined using in situ film zymography or by using an antibody that binds to the active form of MMP-9, e.g., to an active site on MMP-9. Examples of such antibodies include 539A-M0166-F10 and 539A-M0240-B03. As support for this model, experiments were performed using BxPC-3 cells which express active MMP-14 (bind DX-2400) but a tumor of these cells in a xenograft model did not respond in vivo to DX-2400 treatment (see  FIG. 3 ). After analyzing the tumor tissue, it was determined that these cells had very high levels of active MMP-9 (data not shown). 
     The present invention is based at least in part on the observation that certain cancers, particularly osteotropic cancer or bone metastatic cancer cell lines, express MMP-14 and activate proMMP-2, and that MMP-14 inhibitors show enhanced efficacy in cancer cells expressing MMP-14, MMP-2 and/or MMP-9. 
     MMP-14 
     MMP-14 is encoded by a gene designated as MMP-14, matrix metalloproteinase-14 precursor. Synonyms for MMP-14 include matrix metalloproteinase 14 (membrane-inserted), membrane-type-1 matrix metalloproteinase, membrane-type matrix metalloproteinase 1, MMP-14, MMP-X1, MT1MMP, MT1-MMP, MTMMP1, MT-MMP 1. MT-MMPs have similar structures, including a signal peptide, a prodomain, a catalytic domain, a hinge region, and a hemopexin domain (Wang, et al., 2004, J Biol Chem, 279:51148-55). According to SwissProt entry P50281, the signal sequence of MMP-14 precursor includes amino acid residues 1-20. The pro-peptide includes residues 21-111. Cys93 is annotated as a possible cysteine switch. Residues 112 through 582 make up the mature, active protein. The catalytic domain includes residues 112-317. The hemopexin domains includes residues 318-523. The transmembrane segment comprises residues 542 through 562. 
     MMP-14 can be shed from cells or found on the surface of cells, tethered by a single transmembrane amino-acid sequence. See, e.g., Osnkowski et al. (2004, J Cell Physiol, 200:2-10).

     An exemplary MMP-14 gene can consist of or comprise the human or mouse MMP-14 mRNA sequence, a sequence that is 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% identical to one of these sequences, or a fragment thereof. 
     MMP-2 
     MMP-14 activates pro-MMP-2 causing a cascade of proteolysis that facilitates the mobility and invasiveness of tumor cells (Berno, et al., 2005, Endocr Relat Cancer, 12:393-406; Anilkumar, et al., 2005, Faseb J, 19:1326-8; Itoh and Seiki, 2005, J Cell Physiol; Lopez de Cicco, et al., 2005, Cancer Res, 65:4162-71; El Bedoui, et al., 2005, Cardiovasc Res, 67:317-25; Cao, et al., 2005, Thromb Haemost, 93:770-8; Sato, et al., 2005, Cancer Sci, 96:212-7; Dong, et al., 2005, Am J Pathol, 166:1173-86; Philip, et al., 2004, Glycoconj J, 21:429-41; Guo, et al., 2005, Am J Pathol, 166:877-90; Grossman, 2005, Urol Oncol, 23:222; Gilles, et al., 2001, J Cell Sci, 114:2967-76). Studies propose that this activation process requires both active MT1-MMP and the TIMP-2-bound MT1-MMP (Strongin et al, 1995, J Biol Chem, 270, 5331-5338; Butler et al, 1998, J Biol Chem, 273: 871-80; Kinoshita et al, 1998, J Biol Chem, 273, 16098-103). The TIMP-2 in the latter complex binds, through its C-terminal domain, to the hemopexin domain of pro-MMP-2, which may localize the zymogen close to the active MT1-MMP (Butler et al, 1998, J Biol Chem, 273: 871-80; Kinoshita et al, 1998). 
     MMP-2 is encoded by a gene designated as MMP-2, matrix metalloproteinase 2 preproprotein. Synonyms for MMP-2 include matrix metalloproteinase 2 (gelatinase A, 72 kD gelatinase, 72 kD type IV collagenase), TBE-1 (as secreted by H-ras oncogene-transformed human bronchial epithelial cells), MMP-II, CLG4, and CLG4A.

     An exemplary MMP-2 gene can consist of or comprise the human or mouse MMP-2 mRNA sequence, a sequence that is 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% identical to one of these sequences, or a fragment thereof. 
     MMP-9 
     MMP-9 is a Zn+2 dependent endopeptidase, synthesized and secreted in monomeric form as zymogen. The structure is almost similar to MMP2. The nascent form of the protein shows an N-terminal signal sequence (“pre” domain) that directs the protein to the endoplasmic reticulum. The pre domain is followed by a propeptide-“pro” domain that maintains enzyme-latency until cleaved or disrupted, and a catalytic domain that contains the conserved zinc-binding region. A hemopexin/vitronectin-like domain is also seen, that is connected to the catalytic domain by a hinge or linker region. The hemopexin domain is involved in TIMP (Tissue Inhibitors of Metallo-Proteinases) binding e.g., TIMP-1 &amp; TIMP-3, the binding of certain substrates, membrane activation, and some proteolytic activities. It also shows a series of three head-to-tail cysteine-rich repeats within its catalytic domain. These inserts resemble the collagen-binding type II repeats of fibronectin and are required to bind and cleave collagen and elastin. 
     Its primary function is degradation of proteins in the extracellular matrix. It proteolytically digests decorin, elastin, fibrillin, laminin, gelatin (denatured collagen), and types IV, V, XI and XVI collagen and also activates growth factors like proTGFb and proTNFa. Physiologically, MMP-9 in coordination with other MMPs, play a role in normal tissue remodeling events such as neurite growth, embryonic development, angiogenesis, ovulation, mammary gland involution and wound healing. MMP-9 with other MMPs is also involved in osteoblastic bone formation and/or inhibits osteoclastic bone resorption. 
     MMP-9 is encoded by a gene designated as matrix metallopeptidase 9 (gelatinase B, 92 kDa gelatinase, 92 kDa type IV collagenase). Synonyms for MMP-9 include CLG4 (Collagenase Type IV), CLG4B (Collagenase Type IV-B), and GELB (Gelatinase B).

     An exemplary MMP-9 gene can consist of or comprise the human or mouse MMP-9 mRNA sequence, a sequence that is 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% identical to one of these sequences, or a fragment thereof. 
     Methods of evaluating levels of gene expression and protein activity, as well as evaluating the amounts of gene or protein molecules in a sample, are well-known in the art. Exemplary methods by which the expression of the MMP-14, MMP-2 or MMP-9 genes or the activity of the MMP-14, MMP-2 or MMP-9 proteins may be determined are further described below. 
     In certain embodiments, a method of evaluating the expression and/or activity of MMP-14, MMP-2 and/or MMP-9 in a cell may comprise a) determining in the cell the level of expression and/or activity of MMP-14, MMP-2 and/or MMP-9. The method may in certain embodiments further comprise calculating a ratio of the expression and/or activity level of two of MMP-14, MMP-2 and/or MMP-9 from the determined levels. 
     The above-described method may further comprise b) comparing the determined level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 with at least one reference set of levels of expression and/or activity of, or ratio of, MMP-14, MMP-2 and/or MMP-9, wherein the reference set indicates the state of the cell associated with the particular level of expression and/or activity of, or ratio of, MMP-14, MMP-2 and/or MMP-9. 
     Comparison to a reference set or profile is particularly useful in applications of the above-described methods, for example, when they are used in methods for diagnosing and prognosing cancer in a subject, or for screening candidate therapeutics for their efficacy in treating cancer or for stratifying patients based on their risk for or stage of cancer or for selecting a therapy for a patient having or suspected of having cancer. In certain preferred embodiments, the cancer is selected from the group consisting of: osteotropic cancer, breast cancer, lung cancer, colon cancer and prostate cancer. 
     Comparison of the expression and/or activity level of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 with reference expression and/or activity levels, or ratios, e.g., expression and/or activity levels in diseased cells of a subject having cancer or in normal counterpart cells, is preferably conducted using computer systems. In one embodiment, expression and/or activity levels are obtained in two cells and these two sets of expression and/or activity levels are introduced into a computer system for comparison. In a preferred embodiment, one set of expression and/or activity levels is entered into a computer system for comparison with values that are already present in the computer system, or in computer-readable form that is then entered into the computer system. 
     In one embodiment, the invention provides computer readable forms of the gene expression or protein activity profile data of the invention, or of values corresponding to the level of expression and/or activity of, or ratios of the level of expression and/or activity of, MMP-14, MMP-2 and/or MMP-9. The values may be, for example, mRNA expression levels or AQUA™ scores. The values may also be mRNA levels, AQUA™ scores, or other measure of gene expression and/or protein activity normalized relative to a reference gene whose expression or protein whose activity is constant in numerous cells under numerous conditions. In other embodiments, the values in the computer are ratios of, or differences between, normalized or non-normalized levels in different samples. 
     The profile data may be in the form of a table, such as an Excel table. The data may be alone, or it may be part of a larger database, e.g., comprising other profiles. For example, the profile data of the invention may be part of a public database. The computer readable form may be in a computer. In another embodiment, the invention provides a computer displaying the profile data. 
     In one embodiment, the invention provides methods for determining the similarity between the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in a first cell, e.g., a cell of a subject, and that in a second cell, comprising obtaining the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in a first cell and entering these values into a computer comprising a database including records comprising values corresponding to levels of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in a second cell, and processor instructions, e.g., a user interface, capable of receiving a selection of one or more values for comparison purposes with data that is stored in the computer. The computer may further comprise a means for converting the comparison data into a diagram or chart or other type of output. 
     In another embodiment, at least one value representing the expression and/or activity level of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 is entered into a computer system, comprising one or more databases with reference expression and/or activity levels, or ratios, obtained from more than one cell. For example, a computer may comprise expression and/or activity and/or ratio data of diseased and normal cells. Instructions are provided to the computer, and the computer is capable of comparing the data entered with the data in the computer to determine whether the data entered is more similar to that of a normal cell or of a diseased cell. 
     In another embodiment, the computer comprises values of expression and/or activity levels, or ratios, in cells of subjects at different stages of cancer and the computer is capable of comparing expression and/or activity and/or ratio data entered into the computer with the data stored, and produce results indicating to which of the expression and/or activity and/or ratio profiles in the computer, the one entered is most similar, such as to determine the stage of cancer in the subject. 
     In yet another embodiment, the reference expression and/or activity and/or ratio profiles in the computer are expression and/or activity and/or ratio profiles from cells of one or more subjects having cancer, which cells are treated in vivo or in vitro with a drug used for therapy of cancer. Upon entering of expression and/or activity and/or ratio data of a cell of a subject treated in vitro or in vivo with the drug, the computer is instructed to compare the data entered to the data in the computer, and to provide results indicating whether the expression and/or activity data input into the computer are more similar to those of a cell of a subject that is responsive to the drug or more similar to those of a cell of a subject that is not responsive to the drug. Thus, the results indicate whether the subject is likely to respond to the treatment with the drug (e.g., more likely to respond than not, e.g., greater than 50% likelihood of responding) or unlikely to respond to it (e.g., greater than 50% likelihood of not responding). 
     In one embodiment, the invention provides systems comprising a means for receiving expression and/or activity and/or ratio data for one or a plurality of genes and/or protein; a means for comparing the expression and/or activity and/or ratio data from each of said one or plurality of genes and/or proteins to a common reference frame; and a means for presenting the results of the comparison. A system may further comprise a means for clustering the data. 
     In another embodiment, the invention provides computer programs for analyzing expression and/or activity and/or ratio data comprising (a) a computer code that receives as input expression and/or activity and/or ratio data for at least one gene and (b) a computer code that compares said expression and/or activity and/or ratio data from each gene to a common reference frame. 
     The invention also provides machine-readable or computer-readable media including program instructions for performing the following steps: (a) comparing at least one value corresponding to the expression and/or activity level of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in a query cell with a database including records comprising reference expression and/or activity and/or ratio data of one or more reference cells and an annotation of the type of cell; and (b) indicating to which cell the query cell is most similar based on similarities of expression and/or activity profiles and/or ratios. The reference cells may be cells from subjects at different stages of cancer. The reference cells may also be cells from subjects responding or not responding to a particular drug treatment and optionally incubated in vitro or in vivo with the drug. 
     The reference cells may also be cells from subjects responding or not responding to several different treatments, and the computer system indicates a preferred treatment for the subject. Accordingly, the invention provides methods for selecting a therapy for a patient having cancer; the methods comprising: (a) providing the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in a diseased cell of the patient; (b) providing a plurality of reference profiles, each associated with a therapy; and (c) selecting the reference profile most similar to the subject expression and/or activity profile, or ratio, to thereby select a therapy for said patient. In a preferred embodiment step (c) is performed by a computer. The most similar reference profile or ratio may be selected by weighing a comparison value of the plurality using a weight value associated with the corresponding expression and/or activity data, or ratio. 
     A computer readable medium may further comprise a pointer to a descriptor of a stage of cancer or to a treatment for cancer. 
     In operation, the means for receiving expression and/or activity data, or ratios, the means for comparing the expression and/or activity data, or ratios, the means for presenting, the means for normalizing, and the means for clustering within the context of the systems of the present invention may involve a programmed computer with the respective functionalities described herein, implemented in hardware or hardware and software; a logic circuit or other component of a programmed computer that performs the operations specifically identified herein, dictated by a computer program; or a computer memory encoded with executable instructions representing a computer program that may cause a computer to function in the particular fashion described herein. 
     Those skilled in the art will understand that the systems and methods of the present invention may be applied to a variety of systems, including IBM®-compatible personal computers running MS-DOS® or Microsoft WINDOWS®. In an exemplary implementation, expression profiles are compared using a method described in U.S. Pat. No. 6,203,987. A user first loads expression profile or ratio data into the computer system. Geneset profile or ratio definitions are loaded into the memory from the storage media or from a remote computer, preferably from a dynamic geneset database system, through the network. Next the user causes execution of projection software which performs the steps of converting expression and/or activity profile, or ratio, to projected expression and/or activity profiles or ratios. The projected expression and/or activity profiles, or ratios, are then displayed. 
     In yet another exemplary implementation, a user first leads a projected profile or ratio into the memory. The user then causes the loading of a reference profile or ratio into the memory. Next, the user causes the execution of comparison software which performs the steps of objectively comparing the profiles or ratios. 
     Exemplary diagnostic tools and assays are set forth below, which comprise the above-described methodology. 
     In one embodiment, the invention provides methods for determining whether a subject has or is likely to develop cancer, comprising determining the level of expression and/or activity of MMP-14, MMP-2 and/or MMP-9 in a cell of the subject and comparing these levels of expression and/or activity, or ratio of the levels, with the levels of expression of or ratios of MMP-14, MMP-2 and/or MMP-9 in a diseased cell of a subject known to have cancer, such that a similar level of expression and/or activity of, or ratio of, MMP-14, MMP-2 and/or MMP-9 is indicative that the subject has or is likely to develop cancer or at least a symptom thereof. In a preferred embodiment, the cell is essentially of the same type as that which is diseased in the subject. 
     In another embodiment the expression and/or activity profiles, or ratios, of genes in the cell may be used to confirm that a subject has a specific type of cancer, and in particular, that the subject does not have a related disease or disease with similar symptoms. This may be important, in particular, in designing an optimal therapeutic regimen for the subject. It has been described in the art that expression and/or activity profiles or ratios may be used to distinguish one type of disease from a similar disease. For example, two subtypes of non-Hodgkin&#39;s lymphomas, one of which responds to current therapeutic methods and the other one which does not, could be differentiated by investigating 17,856 genes in specimens of patients suffering from diffuse large B-cell lymphoma (Alizadeh et al.  Nature  (2000) 405:503). Similarly, subtypes of cutaneous melanoma were predicted based on profiling 8150 genes (Bittner et al.  Nature  (2000) 406:536). In this case, features of the highly aggressive metastatic melanomas could be recognized. Numerous other studies comparing expression and/or activity profiles or ratios of cancer cells and normal cells have been described, including studies describing expression profiles distinguishing between highly and less metastatic cancers and studies describing new subtypes of diseases, e.g., new tumor types (see, e.g., Perou et al. (1999)  PNAS  96: 9212; Perou et al. (2000)  Nature  606:747; Clark et al. (2000)  Nature  406:532; Alon et al. (1999)  PNAS  96:6745; Golub et al. (1999)  Science  286:531). Such distinction is known in the art as “differential diagnosis”. 
     In yet another embodiment, the invention provides methods for determining the stage of cancer, i.e., for “staging” cancer. It is thought that the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 changes with the stage of the disease. This could be confirmed, e.g., by analyzing the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in subjects having cancer at different stages, as determined by traditional methods. For example, the expression profile of a diseased cell in subjects at different stages of the disease may be determined as described herein. Then, to determine the stage of cancer in a subject, the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9, which varies with the stage of the disease, is determined. A similar level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 between that in a subject and that in a reference profile of a particular stage of the disease, indicates that the disease of the subject is at the particular stage. 
     Similarly, the methods may be used to determine the stage of the disease in a subject undergoing therapy, and thereby determine whether the therapy is effective. Accordingly, in one embodiment, the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 is determined in a subject before the treatment and several times during the treatment. For example, a sample of RNA may be obtained from the subject and analyzed before the beginning of the therapy and every 12, 24, 36, 48, 60, or 72 hours during the therapy. Alternatively or in addition, samples may be analyzed once a week or once a month or once a year, e.g., over the course of the therapy. Changes in expression and/or activity levels of, or ratios of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 over time and relative to diseased cells and normal cells will indicate whether the therapy is effective. 
     Further, the methods may be used to determine the stage of the disease in a subject after undergoing therapy, e.g., and thereby determine whether the therapy was effective and/or whether the disease is re-developing (e.g., whether the disease has returned, e.g., whether the disease has relapsed). Accordingly, in one embodiment, the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 is determined in a subject during and/or immediately after the treatment and/or several times after the treatment. For example, a sample of RNA may be obtained from the subject and analyzed at the end of the therapy and once a week, once a month or once a year, e.g., for the next 1, 2, 3, 4, or 5 years. Changes in expression and/or activity levels of, or ratios of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 over time and relative to diseased cells and normal cells can indicate whether the therapy was effective, and/or whether the disease is re-developing. 
     In yet another embodiment, the invention provides methods for determining the likelihood of success of a particular therapy in a subject having cancer. In one embodiment, a subject is started on a particular therapy, and the effectiveness of the therapy is determined, e.g., by determining the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in a cell of the subject. A normalization of the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9, i.e., a change in the expression and/or activity of level, or ratio, of the gene(s) such that their level of expression and/or activity or ratio, resembles more that of a non diseased cell, indicates that the treatment should be effective in the subject. 
     Prediction of the outcome of a treatment in a subject may also be undertaken in vitro. In one embodiment, cells are obtained from a subject to be evaluated for responsiveness to the treatment, and incubated in vitro with the therapeutic drug. The level of expression and/or activity of MMP-14, MMP-2 and/or MMP-9 is then measured in the cells and these values are compared to the level of expression and/or activity of MMP-14, MMP-2 and/or MMP-9 in a cell which is the normal counterpart cell of a diseased cell. The level of expression and/or activity may also be compared to that in a normal cell. In certain embodiments, the ratio of the level of expression and/or activity of two of MMP-14, MMP-2 and/or MMP-9 may be used. The comparative analysis is preferably conducted using a computer comprising a database of expression and/or activity profiles, or ratios, as described above. A level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in the cells of the subject after incubation with the drug that is similar to their level of expression and/or activity, or ratio of the level of expression and/or activity, in a normal cell and different from that in a diseased cell is indicative that it is likely that the subject will respond positively to a treatment with the drug. On the contrary, a level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in the cells of the subject after incubation with the drug that is similar to their level of expression and/or activity, or ratio, in a diseased cell and different from that in a normal cell is indicative that it is likely that the subject will not respond positively to a treatment with the drug. 
     Since it is possible that a drug does not act directly on the diseased cells, but is, e.g., metabolized, or acts on another cell which then secretes a factor that will effect the diseased cells, the above assay may also be conducted in a tissue sample of a subject, which contains cells other than the diseased cells. For example, a tissue sample comprising diseased cells is obtained from a subject; the tissue sample is incubated with the potential drug; optionally one or more diseased cells are isolated from the tissue sample, e.g., by microdissection or Laser Capture Microdissection (LCM, see infra); and the expression level of MMP-14, MMP-2 and/or MMP-9 is examined. 
     Provided also are methods for selecting a therapy for cancer for a patient from a selection of several different treatments. Certain subjects having cancer may respond better to one type of therapy than another type of therapy. In a preferred embodiment, the method comprises comparing the expression and/or activity level of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 in the patient with that in cells of subjects treated in vitro or in vivo with one of several therapeutic drugs, which subjects are responders or non responders to one of the therapeutic drugs, and identifying the cell which has the most similar level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 to that of the patient, to thereby identify a therapy for the patient. The method may further comprise administering the therapy identified to the subject. 
     Methods of Evaluating the Expression and/or Activity of MMP-14, MMP-2 and/or MMP-9 
     The methods of diagnosing and prognosing cancer by evaluating the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9 and methods of screening candidate therapeutic agents which modulate the expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9, described above, comprise determining the level of expression and/or activity of, or ratio of the level of expression and/or activity of two of, MMP-14, MMP-2 and/or MMP-9. 
     Methods for determining the expression level and ultimately the activity of MMP-14, MMP-2 and/or MMP-9 are well known in the art (and the ratio of such levels may be determined from the determined levels). For example, the expression level of MMP-14, MMP-2 and/or MMP-9 can be determined by reverse transcription-polymerase chain reaction (RT-PCR); dotblot analysis; Northern blot analysis and in situ hybridization. Alternatively, the level of MMP-14, MMP-2 and/or MMP-9 can be analyzed using an appropriate antibody. In certain embodiments, the amounts of MMP-14, MMP-2 and/or MMP-9 is determined using antibodies against MMP-14, MMP-2 and/or MMP-9. 
     In certain embodiments, the level of expression of MMP-14, MMP-2 and/or MMP-9 is determined by determining its AQUA™ score, e.g., by using the AQUA™ automated pathology system. AQUA™ (for Automated Quantitative Analysis) is a method of analysis of absolute measurement of protein expression in situ. This method allows measurements of protein expression within sub-cellular compartments that results in a number directly proportional to the number of molecules expressed per unit area. For example, to measure nuclear estrogen receptor (ER), the tissue is “masked” using keratin in one channel to normalize the area of tumor and to remove the stromal and other non-tumor material from analysis. Then an image is taken using DAPI to define a nuclear compartment. The pixels within the mask and within the DAPI-defined compartment are defined as nuclear. The intensity of expression of ER is then measured using a third channel. The intensity of that subset of pixels divided by the number of pixels (to normalize the area from spot to spot) to give an AQUA™ score. This score is directly proportional to the number of molecules of ER per unit area of tumor, as assessed by a standard curve of cell lines with known levels of ER protein expression. This method, including details of out-of-focus light subtraction imaging methods, is described in detail in a Nature Medicine paper (Camp, R. L., Chung, G. G. &amp; Rimm, D. L. Automated subcellular localization and quantification of protein expression in tissue microarrays.  Nat Med  8, 1323-7 (2002)), as well as U.S. Ser. No. 10/062,308, filed Feb. 1, 2002, both of which reference are incorporated herein by their entireties. 
     In other embodiments, methods of detecting the level of expression of MMP-14, MMP-2 and/or MMP-9 may comprise the use of a microarray. Arrays are often divided into microarrays and macroarrays, where microarrays have a much higher density of individual probe species per area. Microarrays may have as many as 1000 or more different probes in a 1 cm 2  area. There is no concrete cut-off to demarcate the difference between micro- and macroarrays, and both types of arrays are contemplated for use with the invention. 
     Microarrays are known in the art and generally consist of a surface to which probes that correspond in sequence to gene products (e.g., cDNAs, mRNAs, oligonucleotides) are bound at known positions. In one embodiment, the microarray is an array (e.g., a matrix) in which each position represents a discrete binding site for a product encoded by a gene (e.g., a protein or RNA), and in which binding sites are present for products of most or almost all of the genes in the organism&#39;s genome. In certain embodiments, the binding site or site is a nucleic acid or nucleic acid analogue to which a particular cognate cDNA can specifically hybridize. The nucleic acid or analogue of the binding site may be, e.g., a synthetic oligomer, a full-length cDNA, a less-than full length cDNA, or a gene fragment. 
     Although in certain embodiments the microarray contains binding sites for products of all or almost all genes in the target organism&#39;s genome, such comprehensiveness is not necessarily required. Usually the microarray will have binding sites corresponding to at least 100, 500, 1000, 4000 genes or more. In certain embodiments, arrays will have anywhere from about 50, 60, 70, 80, 90, or even more than 95% of the genes of a particular organism represented. The microarray typically has binding sites for genes relevant to testing and confirming a biological network model of interest. Several exemplary human microarrays are publicly available. 
     The probes to be affixed to the arrays are typically polynucleotides. These DNAs can be obtained by, e.g., polymerase chain reaction (PCR) amplification of gene segments from genomic DNA, cDNA (e.g., by RT-PCR), or cloned sequences. PCR primers are chosen, based on the known sequence of the genes or cDNA, which result in amplification of unique fragments (e.g., fragments that do not share more than 10 bases of contiguous identical sequence with any other fragment on the microarray). Computer programs are useful in the design of primers with the required specificity and optimal amplification properties. See, e.g., Oligo pl version 5.0 (National Biosciences). In an alternative embodiment, the binding (hybridization) sites are made from plasmid or phage clones of genes, cDNAs (e.g., expressed sequence tags), or inserts therefrom (Nguyen et al., 1995 , Genomics  29:207-209). 
     A number of methods are known in the art for affixing the nucleic acids or analogues to a solid support that makes up the array (Schena et al., 1995 , Science  270:467-470; DeRisi et al., 1996 , Nature Genetics  14:457-460; Shalon et al., 1996 , Genome Res.  6:639-645; and Schena et al., 1995,  Proc. Natl. Acad. Sci. USA  93:10539-11286). 
     Another method for making microarrays is by making high-density oligonucleotide arrays (Fodor et al., 1991 , Science  251:767-773; Pease et al., 1994 , Proc. Natl. Acad. Sci. USA  91:5022-5026; Lockhart et al., 1996 , Nature Biotech  14:1675; U.S. Pat. Nos. 5,578,832; 5,556,752; and 5,510,270; Blanchard et al., 1996, 11: 687-90). 
     Other methods for making microarrays, e.g., by masking (Maskos and Southern, 1992 , Nuc. Acids Res.  20:1679-1684), may also be used. In principal, any type of array, for example, dot blots on a nylon hybridization membrane (see Sambrook et al., Molecular Cloning—A Laboratory Manual (2nd Ed.), Vol. 1-3, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y., 1989), could be used, as will be recognized by those of skill in the art. 
     The nucleic acids to be contacted with the microarray may be prepared in a variety of ways, and may include nucleotides of the subject invention. Such nucleic acids are often labeled fluorescently. Nucleic acid hybridization and wash conditions are chosen so that the population of labeled nucleic acids will specifically hybridize to appropriate, complementary nucleic acids affixed to the matrix. Non-specific binding of the labeled nucleic acids to the array can be decreased by treating the array with a large quantity of non-specific DNA—a so-called “blocking” step. 
     When fluorescently labeled probes are used, the fluorescence emissions at each site of a transcript array may be detected by scanning confocal laser microscopy. When two fluorophores are used, a separate scan, using the appropriate excitation line, is carried out for each of the two fluorophores used. Fluorescent microarray scanners are commercially available from Affymetrix, Packard BioChip Technologies, BioRobotics and many other suppliers. Signals are recorded, quantitated and analyzed using a variety of computer software. 
     According to the method of the invention, the relative abundance of an mRNA in two cells or cell lines is scored as a perturbation and its magnitude determined (i.e., the abundance is different in the two sources of mRNA tested), or as not perturbed (i.e., the relative abundance is the same). As used herein, a difference between the two sources of RNA of at least a factor of about 25% (RNA from one source is 25% more abundant in one source than the other source), more usually about 50%, even more often by a factor of about 2 (twice as abundant), 3 (three times as abundant) or 5 (five times as abundant) is scored as a perturbation. Present detection methods allow reliable detection of difference of an order of about 2-fold to about 5-fold, but more sensitive methods are expected to be developed. 
     In addition to identifying a perturbation as positive or negative, it is advantageous to determine the magnitude of the perturbation. This can be carried out, as noted above, by calculating the ratio of the emission of the two fluorophores used for differential labeling, or by analogous methods that will be readily apparent to those of skill in the art. 
     In certain embodiments, the data obtained from such experiments reflects the relative expression of each gene represented in the microarray. Expression levels in different samples and conditions may now be compared using a variety of statistical methods. 
     In certain embodiments, the cell comprises a tissue sample, which may be present on a tissue microarray. For example, paraffin-embedded formalin-fixed specimens may be prepared, and punch “biopsy” cores taken from separate areas of the specimens. Each core may be arrayed into a separate recipient block, and sections cut and processed as previously described, for example, in Konenen, J. et al., Tissue microarrays for high-throughput molecular profiling of tumor specimens, (1987)  Nat. Med.  4:844-7 and Chung, G. G. et al.,  Clin. Cancer Res . (In Press). 
     In other embodiments, the cell comprises a cell culture pellet, which may be present on a cell culture pellet microarray. 
     In certain embodiments, it is sufficient to determine the expression of one or only a few genes, as opposed to hundreds or thousands of genes. Although microarrays may be used in these embodiments, various other methods of detection of gene expression are available. This section describes a few exemplary methods for detecting and quantifying mRNA or polypeptide encoded thereby. Where the first step of the methods includes isolation of mRNA from cells, this step may be conducted as described above. Labeling of one or more nucleic acids may be performed as described above. 
     In one embodiment, mRNA obtained from a sample is reverse transcribed into a first cDNA strand and subjected to PCR, e.g., RT-PCR. House keeping genes, or other genes whose expression does not vary may be used as internal controls and controls across experiments. Following the PCR reaction, the amplified products may be separated by electrophoresis and detected. By using quantitative PCR, the level of amplified product will correlate with the level of RNA that was present in the sample. The amplified samples may also be separated on an agarose or polyacrylamide gel, transferred onto a filter, and the filter hybridized with a probe specific for the gene of interest. Numerous samples may be analyzed simultaneously by conducting parallel PCR amplification, e.g., by multiplex PCR. 
     “Dot blot” hybridization has gained wide-spread use, and many versions were developed (see, e.g., M. L. M. Anderson and B. D. Young, in  Nucleic Acid Hybridization - A Practical Approach , B. D. Hames and S. J. Higgins, Eds., IRL Press, Washington D.C., Chapter 4, pp. 73-111, 1985). 
     In another embodiment, mRNA levels is determined by dot blot analysis and related methods (see, e.g., G. A. Beltz et al., in  Methods in Enzymology , Vol. 100, Part B, R. Wu, L. Grossmam, K. Moldave, Eds., Academic Press, New York, Chapter 19, pp. 266-308, 1985). In one embodiment, a specified amount of RNA extracted from cells is blotted (i.e., non-covalently bound) onto a filter, and the filter is hybridized with a probe of the gene of interest. Numerous RNA samples may be analyzed simultaneously, since a blot may comprise multiple spots of RNA. Hybridization is detected using a method that depends on the type of label of the probe. In another dot blot method, one or more probes for a biomarker are attached to a membrane, and the membrane is incubated with labeled nucleic acids obtained from and optionally derived from RNA of a cell or tissue of a subject. Such a dot blot is essentially an array comprising fewer probes than a microarray. 
     Another format, the so-called “sandwich” hybridization, involves covalently attaching oligonucleotide probes to a solid support and using them to capture and detect multiple nucleic acid targets (see, e.g., M. Ranki et al. (1983)  Gene,  21:77-85; A. M. Palva, et al, in UK Patent Application GB 2156074A, Oct. 2, 1985; T. M. Ranki and H. E. Soderlund in U.S. Pat. No. 4,563,419, Jan. 7, 1986; A. D. B. Malcolm and J. A. Langdale, in PCT WO 86/03782, Jul. 3, 1986; Y. Stabinsky, in U.S. Pat. No. 4,751,177, Jan. 14, 1988; T. H. Adams et al., in PCT WO 90/01564, Feb. 22, 1990; R. B. Wallace et al. (1979)  Nucleic Acid Res.  6,11:3543; and B. J. Connor et al. (1983)  PNAS  80:278-282). Multiplex versions of these formats are called “reverse dot blots.” 
     mRNA levels may also be determined by Northern blots. Specific amounts of RNA are separated by gel electrophoresis and transferred onto a filter which is then hybridized with a probe corresponding to the gene of interest. This method, although more burdensome when numerous samples and genes are to be analyzed, provides the advantage of being very accurate. 
     Another method for high throughput analysis of gene expression is the serial analysis of gene expression (SAGE) technique, first described in Velculescu et al. (1995)  Science  270, 484-487. Among the advantages of SAGE is that it has the potential to provide detection of all genes expressed in a given cell type, provides quantitative information about the relative expression of such genes, permits ready comparison of gene expression of genes in two cells, and yields sequence information that may be used to identify the detected genes. Thus far, SAGE methodology has proved itself to reliably detect expression of regulated and nonregulated genes in a variety of cell types (Velculescu et al. (1997)  Cell  88, 243-251; Zhang et al. (1997)  Science  276, 1268-1272 and Velculescu et al. (1999)  Nat. Genet.  23, 387-388. 
     Techniques for producing and probing nucleic acids are further described, for example, in Sambrook et al.,  Molecular Cloning: A Laboratory Manual  (New York, Cold Spring Harbor Laboratory, 1989). 
     Alternatively, the level of expression of MMP-14, MMP-2 and/or MMP-9 is determined by in situ hybridization. In one embodiment, a tissue sample is obtained from a subject, the tissue sample is sliced, and in situ hybridization is performed according to methods known in the art, to determine the level of expression of MMP-14, MMP-2 and/or MMP-9. 
     In other methods, the level of expression of MMP-14, MMP-2 and/or MMP-9 is detected by measuring the level of protein encoded by the MMP-14, MMP-2 and/or MMP-9 gene. This may be done, e.g., by immunoprecipitation, ELISA, or immunohistochemistry using an agent, e.g., an antibody, that specifically detects the protein encoded by the gene. Other techniques include Western blot analysis. Immunoassays are commonly used to quantitate the levels of proteins in cell samples, and many other immunoassay techniques are known in the art. The invention is not limited to a particular assay procedure, and therefore is intended to include both homogeneous and heterogeneous procedures. Exemplary immunoassays which may be conducted according to the invention include fluorescence polarization immunoassay (FPIA), fluorescence immunoassay (FIA), enzyme immunoassay (EIA), nephelometric inhibition immunoassay (NIA), enzyme linked immunosorbent assay (ELISA), and radioimmunoassay (RIA). An indicator moiety, or label group, may be attached to the subject antibodies and is selected so as to meet the needs of various uses of the method which are often dictated by the availability of assay equipment and compatible immunoassay procedures. General techniques to be used in performing the various immunoassays noted above are known to those of ordinary skill in the art. 
     In the case of polypeptides which are secreted from cells, the level of expression of these polypeptides may be measured in biological fluids. 
     The above-described methods may be performed using cells grown in cell culture, or on cell or tissue specimens from a subject. Specimens may be obtained from an individual to be tested using either “invasive” or “non-invasive” sampling means. A sampling means is said to be “invasive” if it involves the collection of nucleic acids from within the skin or organs of an animal (including, especially, a murine, a human, an ovine, an equine, a bovine, a porcine, a canine, or a feline animal). Examples of invasive methods include blood collection, semen collection, needle biopsy, pleural aspiration, umbilical cord biopsy, etc. Examples of such methods are discussed by Kim, C. H. et al. (1992)  J. Virol.  66:3879-3882; Biswas, B. et al. (1990)  Annals NY Acad. Sci.  590:582-583; Biswas, B. et al. (1991)  J. Clin. Microbiol.  29:2228-2233. It is also possible to obtain a cell sample from a subject, and then to enrich it in the desired cell type. For example, cells may be isolated from other cells using a variety of techniques, such as isolation with an antibody binding to an epitope on the cell surface of the desired cell type. 
     In certain embodiments, a single cell is used in the analysis. It is also possible to obtain cells from a subject and culture the cells in vitro, such as to obtain a larger population of cells from which RNA may be extracted. Methods for establishing cultures of non-transformed cells, i.e., primary cell cultures, are known in the art. 
     When analyzing from tissue samples or cells from individuals, it may be important to prevent any further changes in gene expression after the tissue or cells has been removed from the subject. Changes in expression levels are known to change rapidly following perturbations, e.g., heat shock or activation with lipopolysaccharide (LPS) or other reagents. In addition, the RNA and proteins in the tissue and cells may quickly become degraded. Accordingly, in a preferred embodiment, the cells obtained from a subject are snap frozen as soon as possible. 
     Agents that Bind MMP-14, MMP-2 and/or MMP-9 
     Provided also are agents that bind MMP-14, MMP-2 and/or MMP-9 polypeptides. Preferably, such agents are anti-MMP-14, MMP-2 and/or MMP-9 antibodies or antigen-binding fragments thereof, including polyclonal and monoclonal antibodies, prepared according to conventional methodology. Antibodies and antigen-binding fragments thereof that bind MMP-14, MMP-2 and/or MMP-9 biomarkers are useful for determining MMP-14, MMP-2 and/or MMP-9 protein levels. 
     Antibodies and antigen-binding fragments thereof that bind MMP-14, MMP-2 and/or MMP-9 and are useful for determining MMP-14, MMP-2 and/or MMP-9 levels, include but are not limited to: antibodies or antigen-binding fragments thereof that bind specifically to a MMP-14, MMP-2 and/or MMP-9 or fragments or analogs thereof. 
     Significantly, as is well-known in the art, only a small portion of an antibody molecule, the paratrope, is involved in the binding of the antibody to its epitope (see, in general, Clark, W. R. (1986) The Experimental Foundations of Modem Immunology, Wiley &amp; Sons, Inc., New York; Roitt, I. (1991) Essential Immunology, 7th Ed., Blackwell Scientific Publications, Oxford). The pFc′ and Fc regions, for example, are effectors of the complement cascade but are not involved in antigen binding. An antibody from which the pFc′ region has been enzymatically cleaved, or which has been produced without the pFc′ region, designated an F(ab′) 2  fragment, retains both of the antigen binding sites of an intact antibody. Similarly, an antibody from which the Fc region has been enzymatically cleaved, or which has been produced without the Fc region, designated an Fab fragment, retains one of the antigen binding sites of an intact antibody molecule. Proceeding further, Fab fragments consist of a covalently bound antibody light chain and a portion of the antibody heavy chain denoted Fd. The Fd fragments are the major determinant of antibody specificity (a single Fd fragment may be associated with up to ten different light chains without altering antibody specificity) and Fd fragments retain epitope-binding ability in isolation. 
     Within the antigen-binding portion of an antibody, as is well-known in the art, there are complementarity determining regions (CDRs), which directly interact with the epitope of the antigen, and framework regions (FRs), which maintain the tertiary structure of the paratope (see, in general, Clark, W. R. (1986) The Experimental Foundations of Modem Immunology, Wiley &amp; Sons, Inc., New York; Roitt, I. (1991) Essential Immunology, 7th Ed., Blackwell Scientific Publications, Oxford). In both the heavy chain Fd fragment and the light chain of IgG immunoglobulins, there are four framework regions (FR1 through FR4) separated respectively by three complementarity determining regions (CDR1 through CDR3). The CDRs, and in particular the CDR3 regions, and more particularly the heavy chain CDR3, are largely responsible for antibody specificity. 
     It is now well-established in the art that the non-CDR regions of a mammalian antibody may be replaced with similar regions of conspecific or heterospecific antibodies while retaining the epitopic specificity of the original antibody. This is most clearly manifested in the development and use of “humanized” antibodies in which non-human CDRs are covalently joined to human FR and/or Fc/pFc′ regions to produce a functional antibody. See, e.g., U.S. Pat. Nos. 4,816,567, 5,225,539, 5,585,089, 5,693,762 and 5,859,205. 
     Fully human monoclonal antibodies also can be prepared by immunizing mice transgenic for large portions of human immunoglobulin heavy and light chain loci. Following immunization of these mice (e.g., XENOMOUSE™ (Abgenix), HUMAB-MOUSE™ (Medarex/GenPharm)), monoclonal antibodies can be prepared according to standard hybridoma technology. These monoclonal antibodies will have human immunoglobulin amino acid sequences and therefore will not provoke human anti-mouse antibody (HAMA) responses when administered to humans. 
     Thus, as will be apparent to one of ordinary skill in the art, the present invention also provides for F(ab′) 2 , Fab, Fv and Fd fragments; chimeric antibodies in which the Fc and/or FR and/or CDR1 and/or CDR2 and/or light chain CDR3 regions have been replaced by homologous human or non-human sequences; chimeric F(ab′) 2  fragment antibodies in which the FR and/or CDR1 and/or CDR2 and/or light chain CDR3 regions have been replaced by homologous human or non-human sequences; chimeric Fab fragment antibodies in which the FR and/or CDR1 and/or CDR2 and/or light chain CDR3 regions have been replaced by homologous human or non-human sequences; and chimeric Fd fragment antibodies in which the FR and/or CDR1 and/or CDR2 regions have been replaced by homologous human or non-human sequences. The present invention also includes so-called single chain antibodies. 
     Thus, the invention involves polypeptides of numerous size and type that bind specifically to MMP-14, MMP-2 and/or MMP-9 polypeptides and nucleic acids. These polypeptides may be derived also from sources other than antibody technology. For example, such polypeptide binding agents can be provided by degenerate peptide libraries which can be readily prepared in solution, in immobilized form or as phage display libraries. Combinatorial libraries also can be synthesized of peptides containing one or more amino acids. Libraries further can be synthesized of peptoids and non-peptide synthetic moieties. 
     Phage display can be particularly effective in identifying binding peptides useful according to the invention. Briefly, one prepares a phage library (using e.g. m13, fd, or lambda phage), displaying inserts from 4 to about 80 amino acid residues using conventional procedures. The inserts may represent, for example, a completely degenerate or biased array. One then can select phage-bearing inserts which bind to MMP-14, MMP-2 and/or MMP-9 molecules. This process can be repeated through several cycles of reselection of phage that bind to the MMP-14, MMP-2 and/or MMP-9 molecules. Repeated rounds lead to enrichment of phage bearing particular sequences. DNA sequence analysis can be conducted to identify the sequences of the expressed polypeptides. The minimal linear portion of the sequence that binds to the MMP-14, MMP-2 and/or MMP-9 molecules can be determined. One can repeat the procedure using a biased library containing inserts containing part of all of the minimal linear portion plus one or more additional degenerate residues upstream or downstream thereof. Yeast two-hybrid screening methods also may be used to identify polypeptides that bind to the MMP-14, MMP-2 and/or MMP-9 molecules. Thus, MMP-14, MMP-2 and/or MMP-9 molecules can be used to screen peptide libraries, including phage display libraries, to identify and select peptide binding partners of the MMP-14, MMP-2 and/or MMP-9 molecules. 
     Exemplary MMP-14 binding proteins that may be used either to detect MMP-14 or inhibit MMP-14 also include those M0031-002, M0031-F01, M0033-H07, M0037-009, M0037-D01, M0038-E06, M0038-F01, M0038-F08, M0039-H08, M0040-A06, M0040-A11, and M0043-G02.

     As detailed herein, the foregoing antibodies and other binding proteins may be used for example to isolate and identify MMP-14, MMP-2 and/or MMP-9 protein, e.g. to detect its expression in tissue samples. The antibodies may be coupled to specific diagnostic labeling agents for imaging of the protein or fragment thereof. Exemplary labels include, but are not limited to, labels which when fused to a MMP-14, MMP-2 and/or MMP-9 molecule produce a detectable fluorescent signal, including, for example, green fluorescent protein (GFP), enhanced green fluorescent protein (EGFP),  Renilla reniformis  green fluorescent protein, GFPmut2, GFPuv4, enhanced yellow fluorescent protein (EYFP), enhanced cyan fluorescent protein (ECFP), enhanced blue fluorescent protein (EBFP), citrine and red fluorescent protein from discosoma (dsRED).

     EXEMPLIFICATION 
     The present invention is further illustrated by the following examples which should not be construed as limiting in any way. 
     Example 1 
     Expression of MMPs in Various Cancer Cell Lines and Correlation to MMP-14 Inhibitor Efficacy 
       FIG. 1  illustrates the relative expression levels of various MMPs, including MMP-14 and MMP-2, in different cancer cell lines. MDA-MB-231 expresses both MMP-14 and MMP-2 in over 50% of cells. MDA-MB-435, BT-474 and PC-3 express only MMP-14 in over 50% of cells. BxPC-3 and B16-F1 express MMP-14 in between 20% and 50% of cells (but not MMP-2). The MCF-7 passage of cells used for these experiments express MMP-14 in between 20% and 50% of cells (but not MMP-2). 
     The effect of DX-2400, an MMP-14 inhibitor, in inhibiting tumor growth, was strongest in MDA-MB-231, MDA-MB-435, BT-474 and PC-3, all of which express MMP-14 in over 50% of cells ( FIGS. 2 and 3 ). Further, DX-2400 had an effect on metastasis on certain cell lines expressing MMP-14 in at least 20% of cells ( FIG. 4 ). 
     Example 2 
     Tumor Growth Data with MMP-14-Positive and MMP-14-Negative Cancer Cells 
       FIG. 5A  shows MMP-14 expression in MDA-MB-231, HUVEC, HT-1080 and MCF-7 cells using a commercial anti-MMP-14 antibody (rabbit polyclonal antibody to MMP-14, Abcam, Cambridge, Mass.). These data show that the MCF-7 cells used for these experiments are negative for MMP-14, in contrast to MDA-MB-231. 
       FIGS. 5B and 5C  show activity of DX-2400 in MDA-MB-231 and MCF-7 tumor xenograft models. As shown in  FIG. 5B , DX-2400 inhibited tumor growth of MDA-MB-231 cells. The results seen with some treatments were statistically significant (see, e.g., DX-2400 10 mg/kg, Q2D). Consistent with the lack of MMP-14 expression in the MCF7 cells used for these experiments, DX-2400 (10 mg/kg, ip, qod) did not inhibit MCF-7 tumor growth after two weeks of treatment ( FIG. 5C ). In these MCF-7 cells, DX-2400 exhibited minimal tumor growth delay (37%) compared to Tamoxifen (83%) after 40 days of treatment. The slight response observed with DX-2400 may be attributed to stromal cells (MMP-14 positive) present in the tumor. 
     Western blot analysis. To perform the Western blot experiments, whole cell protein extracts were prepared from cells using RIPA buffer. Equal amount of proteins (30 μg) was resolved by 4-12% SDS-PAGE and electroblotted to a PVDF membrane. The blot was probed with a rabbit polyclonal antibody to MMP-14 (Abcam, Cambridge, Mass.) followed by an HRP-conjugated goat anti-rabbit antibody (Thermo Fisher Scientific). Proteins were detected using a Super Signal West Femto Maximum Sensitivity Substrate (Thermo Fisher Scientific). The blot was subsequently stripped and reprobed with a mouse monoclonal antibody to 8-actin (Abcam) followed by an HRP-conjugated goat anti-mouse antibody (Thermo Fisher Scientific).
