     INTRODUCTION 
     The present invention relates to variant forms of the receptor for the obese gene product. In particular, the invention relates to methods of detecting receptor variants in the reproductive organs for the diagnosis of the cause of infertility. In addition, it relates to methods of inhibiting or down-regulating expression of defective variants in cells to augment their responsiveness to regulation by leptin as well as methods of using compounds to directly activate signal transduction pathways associated with this ligand-receptor system to improve fertility. 
     BACKGROUND OF THE INVENTION 
     Infertility is a major clinical problem in Western societies. A number of contributing factors have been identified for infertility, which include metabolic diseases in a male that result in insufficient sperm production and the inability of a female&#39;s ovaries to produce or release ova. In addition, pituitary disorders may cause infertility in both sexes because the gonads are responsive to regulation by pituitary hormones such as follicle-stimulating hormone and luteinizing hormone. However, clinical conditions exist in which an infertile female is still capable of ovulating. Therefore, the ovary may respond to additional signals that are not yet identified. 
     Zhang et al. (1994, Nature 372:425-432) describe the cloning and sequencing of the mouse ob gene and its human homolog. In an effort to understand the physiologic function of the ob gene, several independent research groups produced recombinant ob gene product in bacteria for in vivo testing (Pelleymounter et al., 1995, Science 269:540-543; Halaas et al., 1995, Science 269:543-546; Campfield et al., 1995, Science 269:546-549). When the Ob protein (also known as leptin) was injected into grossly obese mice, which possessed two mutant copies of the ob gene, the mice exhibited a reduced appetite and began to lose weight. Similarly, when normal mice received leptin, they also ate less than the untreated controls. Interestingly, when leptin was administered to ob/ob female mice which were always infertile, fertility was restored in these animals (Chehab et al., 1996, Nature Genetics 12:318-320). 
     Recently, a leptin fusion protein was generated and used to screen for the leptin receptor (also known as OB-R) in a cDNA expression library prepared from mouse choroid plexus, a tissue that lines brain cavities termed ventricles (Tartaglia, 1995, Cell 83:1263-1271). This approach led to the cloning of one form of the OB-R coding sequence, which reveals a single membrane-spanning receptor, sharing structural similarities with several Class I cytokine receptors, such as the gpl130 signal-transducing component of the interleukin-6 receptor (Taga et al., 1989, Cell 58:573-581), the granulocyte-colony stimulating factor receptor (Fukunaga et al., 1990, Cell 61:341-350), and the leukemia inhibitory factor receptor (Gearing et al., 1991, EMBO J. 10:2839-2848). Northern blot analysis and reverse transcription-polymerase chain reaction (RT-PCR) demonstrate that OB-R mRNA is expressed in several tissues, including lung, kidney, total brain, choroid plexus and hypothalamus. 
     The reported mouse OB-R protein contains a relatively short intracellular cytoplasmic domain as compared with other Class I cytokine receptors. Subsequently, when cDNA encoding its human homolog was isolated from a human infant brain library, the predicted human protein sequence contains a much longer intracellular domain. In view of this finding, it was speculated that different forms of the receptor might exist (Barinaga, 1996, Science 271:29). However, prior to the resent invention, there was no report on how variant forms of the OB-R in humans would relate to infertility. 
     SUMMARY OF THE INVENTION 
     The present invention relates to variant forms of the human OB-R. In particular, it relates to the detection of these receptor variants in reproductive organs such as the ovary and the prostate gland for diagnosis of the cause of infertility, and methods for treating infertility by targeting these variant receptors. 
     The invention is based, in part, upon the Applicants&#39; discovery of human cDNA clones encoding three variant forms of the OB-R. These receptors differ structurally from a reported OB-R with only three amino acid substitutions in the extracellular domain, but extensive diversity is observed in their intracellular cytoplasmic domains at the 3&#39; end. The cytoplasmic domains of the variants of the invention are both shorter and distinct in nucleotide sequence from the corresponding domain of the published form of OB-R (Tartaglia et al., 1995 Cell 83:1263). In addition, the cytoplasmic domain of one such variant is highly homologous to a human retrotransposon sequence. The OB-R variants described herein represent incomplete receptors which may be incompetent or partially competent in transducing signals upon ligand binding. Expression of the different forms of the receptor have been detected in prostate and ovary. Furthermore, leptin activity has been shown to be naturally present in ovarian follicular fluids. Therefore, a wide variety of uses are encompassed by the present invention, including but not limited to, the detection of the receptor variants in reproductive organs for the diagnosis of infertility, methods to inhibit and/or down-regulate the expression of these receptor variants, gene therapy to replace the receptor variants in homozygous individuals, and direct activation of downstream signal transduction pathways in cells expressing the defective receptor variants for improving fertility.

     DETAILED DESCRIPTION OF THE INVENTION 
     THE OB-R VARIANTS 
     The present invention relates to nucleic acid and amino acid sequences of OB-R variants. In a specific embodiment by way of example in Section 6, infra, three variants were cloned and characterized. Amino acid sequence comparison of these OB-R variants with a published human OB-R sequence (Tartaglia et al., 1995, Cell 83:1263-1271) reveals three amino acid differences in their extracellular domains and extensive diversity in their intracellular cytoplasmic domains. More specifically, FIGS. 1A-1E shows that in the variants, nucleotide residues #349-351 encode alanine, nucleotide residues #421-423 encode arginine and nucleotide residues #763-765 encode arginine. Additionally, the variants diverge both in length and sequence composition from the human OB-R sequence published by Tartaglia et al. from nucleotide residue #2770 and beyond (FIG. 2). In this regard, the intracellular domain of Form 1 (FIGS. 1A-1E) of the variants is highly homologous to a retrotransposon sequence (Ono et al., 1987, Nucl. Acid. Res. 15:8725-8737). Such variants represent functionally defective forms of human OB-R in signal transduction upon leptin binding. 
     In order to clone additional variant forms of the molecule, labeled DNA probes made from nucleic acid fragments corresponding to any portion of the cDNA disclosed herein may be used to screen a cDNA library prepared from human ovary, human prostate, human fetal liver, human lung, human kidney, human choroid plexus and human hypothalamus. More specifically, oligonucleotides corresponding to either the 5&#39; or 3&#39; terminus of the cDNA sequence may be used to obtain longer nucleotide sequences. Briefly, the library may be plated out to yield a maximum of 30,000 pfu for each 150 mm plate. Approximately 40 plates may be screened. The plates are incubated at 37° C. until the plaques reach a diameter of 0.25 mm or are just beginning to make contact with one another (3-8 hours). Nylon filters are placed onto the soft top agarose and after 60 seconds, the filters are peeled off and floated on a DNA denaturing solution consisting of 0.4 N sodium hydroxide. The filters are then immersed in neutralizing solution consisting of 1 M Tris HCL, pH 7.5, before being allowed to air dry. The filters are prehybridized in casein hybridization buffer containing 10% dextran sulfate, 0.5 M NaCl, 50 mM Tris HCL, pH 7.5, 0.1% sodium pyrophosphate, 1% casein, 1% SDS, and denatured salmon sperm DNA at 0.5 mg/ml for 6 hours at 60° C. The radiolabelled probe is then denatured by heating to 95° C. for 2 minutes and then added to the prehybridization solution containing the filters. The filters are hybridized at 60° C. for 16 hours. The filters are then washed in 1X wash mix (10X wash mix contains 3 M NaCl, 0.6 M Tris base, and 0.02 M EDTA) twice for 5 minutes each at room temperature, then in 1X wash mix containing 1% SDS at 60° C. for 30 minutes, and finally in 0.3X wash mix containing 0.1% SDS at 60° C. for 30 minutes. The filters are then air dried and exposed to x-ray film for autoradiography. After developing, the film is aligned with the filters to select a positive plaque. If a single, isolated positive plaque cannot be obtained, the agar plug containing the plaques will be removed and placed in lambda dilution buffer containing 0.1 M NaCl, 0.01 M magnesium sulfate, 0.035 M Tris Hcl, pH 7.5, 0.01% gelatin. The phage may then be replated and rescreened to obtain single, well isolated positive plaques. Positive plaques may be isolated and the cDNA clones sequenced using primers based on the known cDNA sequence. This step may be repeated until a full length cDNA is obtained. 
     One method for identifying all 3&#39; isoforms is to PCR amplify the 3&#39; ends of the variant cDNA from a variety of tissues including but not limiting to, choroid plexus, hypothalamus, fetal liver, bone marrow, ovary, or prostate. To obtain the 3&#39; end of the cDNA, an oligo-dT primer is used to synthesize the cDNA first strand. OB-R specific primers from the conserved region of the gene (e.g. up stream of nucleotide 2770) and oligo-dT are then used to amplify the 3&#39; end. The PCR fragments are cloned and sequenced by standard techniques. Once obtained, these sequences may be translated into amino acid sequence and examined for certain landmarks such as continuous open reading frame, regulatory regions that associate with tyrosine kinase activation, and finally overall structural similarity to known OB-R variants. These 3&#39; variants may represent additional signal transduction defective forms of OB-R. 
     EXPRESSION OF THE OB-R VARIANTS 
     In accordance with the invention, the OB-R variant polynucleotide sequence which encodes a protein, peptide fragments, fusion proteins or functional equivalents thereof, may be used to generate recombinant DNA molecules that direct the expression of the protein, peptide fragments, fusion proteins or a functional equivalent thereof, in appropriate host cells. Such polynucleotide sequences, as well as other polynucleotides which selectively hybridize to at least a part of such polynucleotides or their complements, may also be used in nucleic acid hybridization assays, Southern and Northern blot analyses, etc. 
     Due to the inherent degeneracy of the genetic code, other DNA sequences which encode substantially the same or a functionally equivalent amino acid sequence, may be used in the practice of the invention for the expression of the OB-R variant. Such DNA sequences include those which are capable of hybridizing to the OB-R variant sequence under stringent conditions, particularly at its 3&#39; end. The phrase &#34;stringent conditions&#34; as used herein refers to those hybridizing conditions that (1) employ low ionic strength and high temperature for washing, for example, 0.015 M NaCl/0.0015 M sodium citrate/0.1% SDS at 50° C.; (2) employ during hybridization a denaturing agent such as formamide, for example, 50% (vol/vol) formamide with 0.1% bovine serum albumin/0.1% Ficoll/0.1% polyvinylpyrrolidone/50 mM sodium phosphate buffer at PH 6.5 with 750 mM NaCl, 75 mM sodium citrate at 42° C.; or (3) employ 50% formamide, 5×SSC (0.75 M NaCl, 0.075 M Sodium pyrophosphate, 5×Denhardt&#39;s solution, sonicated salmon sperm DNA (50 μg/ml), 0.1% SDS, and 10% dextran sulfate at 42° C., with washes at 42° C. in 0.2×SSC and 0.1% SDS. 
     Altered DNA sequences which may be used in accordance with the invention include deletions, additions or substitutions of different nucleotide residues resulting in a sequence that encodes the same or a functionally equivalent gene product. The gene product itself may contain deletions, additions or substitutions of amino acid residues within the OB-R variant sequence, which result in a silent change thus producing a functionally equivalent protein. Such amino acid substitutions may be made on the basis of similarity in polarity, charge, solubility, hydrophobicity, hydrophilicity, and/or the amphipathic nature of the residues involved. For example, negatively charged amino acids include aspartic acid and glutamic acid; positively charged amino acids include lysine, histidine and arginine; amino acids with uncharged polar head groups having similar hydrophilicity values include the following: glycine, asparagine, glutamine, serine, threonine, tyrosine; and amino acids with nonpolar head groups include alanine, valine, isoleucine, leucine, phenylalanine, proline, methionine, tryptophan. 
     The DNA sequence of the invention may be engineered in order to alter the OB-R variant coding sequence for a variety of ends, including but not limited to, alterations which modify processing and expression of the gene product. For example, mutations may be introduced using techniques which are well known in the art, e.g., site-directed mutagenesis, to insert new restriction sites, to alter glycosylation patterns, phosphorylation, etc. In addition, the intracellular domain may also be altered and replaced by a different domain, such as the OB-R intracellular domain by Tartaglia et al. 
     In another embodiment of the invention, the OB-R variant sequence may be ligated to a heterologous sequence to encode a fusion protein. For example, for screening of peptide libraries for inhibitors or stimulators of receptor activity, it may be useful to encode a chimeric protein expressing a heterologous epitope that is recognized by a commercially available antibody. A fusion protein may also be engineered to contain a cleavage site located between the OB-R variant sequence and the heterologous protein sequence, so that the variant may be cleaved away from the heterologous moiety. 
     In an alternate embodiment of the invention, the coding sequence of the OB-R variant could be synthesized in whole or in part, using chemical methods well known in the art. (See, for example, Caruthers et al., 1980, Nuc. Acids Res. Symp. Ser. 7:215-233; Crea and Horn, 180, Nuc. Acids Res. 9(10):2331; Matteucci and Caruthers, 1980, Tetrahedron Letters 21:719; and Chow and Kempe, 1981, Nuc. Acids Res. 9(12):2807-2817). Alternatively, the protein itself could be produced using chemical methods to synthesize OB-R variant amino acid sequence in whole or in part. For example, peptides can be synthesized by solid phase techniques, cleaved from the resin, and purified by preparative high performance liquid chromatography. (e.g., see Creighton, 1983, Proteins Structures And Molecular Principles, W. H. Freeman and Co., N.Y. pp. 50-60). The composition of the synthetic peptides may be confirmed by amino acid analysis or sequencing (e.g., the Edman degradation procedure; see Creighton, 1983, Proteins, Structures and Molecular Principles, W. H. Freeman and Co., N.Y., pp. 34-49). 
     In order to express the OB-R variant in host cells, the nucleotide sequence coding for the variant, or a functional equivalent, is inserted into an appropriate expression vector, i.e., a vector which contains the necessary elements for the transcription and translation of the inserted coding sequence. The expressed gene products as well as host cells or cell lines transfected or transformed with recombinant OB-R variant expression vectors can be used for a variety of purposes. For example, host cells expressing the OB-R variant may be used to verify the ability of this molecule to bind leptin in a binding assay with radiolabeled, enzyme-conjugated or fluorescent dye-conjugated leptin. At the same time, the ability of the molecule to transduce an activation signal in host cells upon binding to leptin may be tested by assaying proliferation or phosphorylation pattern of kinases in the cells. In addition, genetically-engineered host cells can be used to screen for and select agonist and antagonist compounds, including any inhibitors that would interfere with binding of leptin to the extracellular or intracellular domain of the OB-R variant. In that connection, such host cells may be used to screen for and select small molecules i.e., peptides, nucleic acids and synthetic compounds that can supplement the incomplete signal transduced by the OB-R variant following leptin binding. Such small molecules may also affect receptor isoform pairing, thereby modifying the ability of OB-R to respond to leptin. Other uses, include, but are not limited to generating antibodies (i.e., monoclonal or polyclonal) that competitively inhibit activity of an OB-R variant, neutralize its activity, or even enhances it activity. Antibodies may be used in detecting and quantifying expression of OB-R levels in cells and tissues. 
     USES OF OB-R VARIANT POLYNUCLEOTIDES 
     An OB-R variant polynucleotide may be used for diagnostic and/or therapeutic purposes. For diagnostic purposes, an OB-R variant polynucleotide may be used to detect gene expression or aberrant gene expression in infertile individuals as well as in normal individuals to identify predisposition for infertility. Included in the scope of the invention are oligonucleotide sequences, that include antisense RNA and DNA molecules, ribozymes and triplex DNA, that function to inhibit translation of OB-R variant. 
     DIAGNOSTIC USES OF OB-R VARIANT POLYNUCLEOTIDES 
     An OB-R variant polynucleotide may have a number of uses for the diagnosis of the possible causes underlying infertility, resulting from expression of a defective receptor variant. For example, the OB-R variant cytoplasmic domain DNA sequence may be used in hybridization assays of biopsy or autopsy materials obtained from ovary or prostate to diagnose OB-R variant expression; e.g., Southern or Northern analysis, including in situ hybridization assays as well as PCR. Such techniques are well known in the art, and are in fact the basis of many commercially available diagnostic kits. For PCR detection, primers may be designed from a conserved region of the coding sequence and within the 3&#39; region of OB-R variant. The tissues suitable for such analysis include but are not limited to, prostate, ovary, and testes, ova, sperm (semen), and cells in the ovarian follicular fluids. 
     THERAPEUTIC USES OF OB-R VARIANT POLYNUCLEOTIDES 
     An OB-R variant polynucleotide may be useful in the treatment of infertile conditions. By introducing gene sequences into cells, gene therapy can be used to treat conditions in which the cells do not respond to leptin normally due to expression of a defective OB-R variant. In some instances, the polynucleotide encoding a functional OB-R is intended to replace or act in the place of the functionally defective OB-R variant gene. Alternatively, abnormal conditions characterized by expression of two copies of the OB-R variant can be treated using the gene therapy techniques described below. 
     Non-responsiveness to normal levels of leptin may contribute to infertility. This may result from a functionally defective receptor that does not transduce competent signals upon ligand binding. Recombinant gene therapy vectors, such as viral vectors, may be engineered to express signalling competent forms of OB-R which may be used to augment the non-responsiveness of the naturally occurring OB-R variant. A signalling competent form may be, for example, a protein with the same extracellular domain and transmembrane region, but containing all or part of its normal signal transduction domain, such as that described by Tartaglia et al. (1995, Cell 83:1263-1271). Thus, recombinant gene therapy vectors may be used therapeutically for treatment of infertility resulting from expression or activity of the OB-R variant. Accordingly, the invention provides a method of augmenting signal transduction by an endogenous OB-R variant in a cell comprising delivering a DNA molecule encoding a signalling competent form of the OB-R to the cell so that the signalling competent protein is produced in the cell and competes with the endogenous defective OB-R variant for access to molecules in the signalling pathway which does not activate or are not activated by the endogenous natural defective receptor. Additionally, since dimerization of a functional receptor with a defective variant may occur in cells of heterozygous individuals, small molecules may be used to inhibit such pairing, thereby increasing the number of functional dimeric receptors for proper signalling in response to leptin. 
     Expression vectors derived from viruses such as retroviruses, vaccinia virus, adeno-associated virus, herpes viruses, or bovine papilloma virus, may be used for delivery of recombinant functional OB-R into the targeted cell population. Methods which are well known to those skilled in the art can be used to construct recombinant viral vectors containing an OB-R polynucleotide sequence. See, for example, the techniques described in Sambrook et al., 1989, Molecular Cloning A Laboratory Manual, Cold Spring Harbor Laboratory, N.Y. and Ausubel et al., 1989, Current Protocols in Molecular Biology, Greene Publishing Associates and Wiley Interscience, N.Y. Alternatively, recombinant OB-R molecules can be reconstituted into liposomes for delivery to target cells. 
     Oligonucleotide sequences including anti-sense RNA and DNA molecules and ribozymes that function to inhibit the translation of the OB-R variant mRNA are within the scope of the invention. Anti-sense RNA and DNA molecules act to directly block the translation of mRNA by binding to targeted mRNA and preventing protein translation. In regard to antisense DNA, oligodeoxyribonucleotides derived from the OB-R variant nucleotide sequence at nucleotide #2771 and beyond, are preferred. 
     Ribozymes are enzymatic RNA molecules capable of catalyzing the specific cleavage of RNA. The mechanism of ribozyme action involves sequence specific hybridization of the ribozyme molecule to complementary target RNA, followed by endonucleolytic cleavage. Within the scope of the invention are engineered hammerhead motif ribozyme molecules that specifically and efficiently catalyze endonucleolytic cleavage of OB-R variant RNA sequences. 
     Specific ribozyme cleavage sites within any potential RNA target are initially identified by scanning the target molecule for ribozyme cleavage sites which include the following sequences, GUA, GUU and GUC. Once identified, short RNA sequences of between 15 and 20 ribonucleotides corresponding to the region of the target gene containing the cleavage site may be evaluated for predicted structural features such as secondary structure that may render the oligonucleotide sequence unsuitable. The suitability of candidate targets may also be evaluated by testing their accessibility to hybridization with complementary oligonucleotides, using ribonuclease protection assays. 
     Oligodeoxyribonucleotides can form sequence-specific triple helices by hydrogen bonding to specific complementary sequences in duplexed DNA. Interest in triple helices has focused on the potential biological and therapeutic applications of these structures. Formation of specific triple helices may selectively inhibit the replication and/or gene expression of targeted genes by prohibiting the specific binding of functional trans-acting factors. 
     Oligonucleotides to be used in triplex helix formation should be single stranded and composed of deoxynucleotides. The base composition of these oligonucleotides must be designed to promote triple helix formation via Hoogsteen base pairing rules, which generally require sizeable stretches of either purines or pyrimidines to be present on one strand of a duplex. Oligonucleotide sequences may be pyrimidine-based, which will result in TAT and CGC triplets across the three associated strands of the resulting triple helix. The pyrimidine-rich oligonucleotides provide base complementarily to a purine-rich region of a single strand of the duplex in a parallel orientation to that strand. In addition, oligonucleotides may be chosen that are purine-rich, for example, containing a stretch of G residues. These oligonucleotides will form a triple helix with a DNA duplex that is rich in GC pairs, in which the majority of the purine residues are located on a single strand of the targeted duplex, resulting in GGC triplets across the three strands in the triplex. Alternatively, the potential sequences that can be targeted for triple helix formation may be increased by creating a so called &#34;switchback&#34; oligonucleotide. Switchback oligonucleotides are synthesized in an alternating 5&#39;-3&#39;, 3&#39;-5&#39; manner, such that they base pair with first one strand of a duplex and then the other, eliminating the necessity for a sizeable stretch of either purines or pyrimidines to be present on one strand of a duplex. 
     Both anti-sense RNA and DNA molecules and ribozymes of the invention may be prepared by any method known in the art for the synthesis of RNA molecules. These include techniques for chemically synthesizing oligodeoxyribonucleotides well known in the art such as solid phase phosphoramidite chemical synthesis. Alternatively, RNA molecules may be generated by in vitro and in vivo transcription of DNA sequences encoding the antisense RNA molecule. Such DNA sequences may be incorporated into a wide variety of vectors which incorporate suitable RNA polymerase promoters such as the T7 or SP6 polymerase promoters. Alternatively, antisense cDNA constructs that synthesize antisense RNA constitutively or inducibly, depending on the promoter used, can be introduced stably into cell lines. 
     Various modifications to the DNA molecules may be introduced as a means of increasing intracellular stability and half-life. Possible modifications include but are not limited to the addition of flanking sequences of ribo- or deoxy- nucleotides to the 5&#39; and/or 3&#39; ends of the molecule or the use of phosphorothioate or 2&#39; O-methyl rather than phosphodiesterase linkages within the oligodeoxyribonucleotide backbone. 
     ACTIVATION OF TYROSINE KINASE PATHWAYS IN INFERTILITY 
     Many known class I cytokine receptors initiate cell signaling via Janus kinases (JAKs) (Ihle, 1995, Nature 5 377:591-594; Heldin, 1995, Cell 80:213-223; Kishimoto et al, 1994, Cell 76:253-62; Ziemiecki et al, 1994, Trends Cell. Biol. 4:207-212). JAK1-3 have been shown to bind to conserved sequences termed box1 and box2 (Fukunaga et al., 1991, EMBO J. 10:2855-65; Murakami, 1991, Proc. Natl. Acad. Sci. USA 88:11349-53). Ligand binding induces a homo- or hetero-dimerization of receptor chains which activates, by phosphorylation, the JAKs. The activated JAKs, in turn, phosphorylate members of the STAT family (Heldin, 1995, Cell 80:213-223; Kishimoto et al., Blood 86:1243-54; Darnell et al., 1994, Science 264:1415-21; Zhong et al, 1994, Proc. Natl. Acad. Sci. USA 91:4806-10; Hou et al., 1994, Science 265:1701-6). These phosphorylated STATs ultimately translocate to the nucleus, form transcription complexes, and regulate gene expression. Both box1 and box2 are required for complete signaling in certain systems. (Fukunaga et al., 1991, EMBO J. 10:2855-65; Murakami, 1991, Proc. Natl. Acad. Sci. USA 88:11349-53). 
     The OB-R variants disclosed herein have a typical box1 (from nucleotide #2707-2730) that contains the critical xWxxxPxP amino acid sequence, but they do not contain an obvious box2 nor further downstream sequences that are important for normal receptor activation. Therefore, it is possible to use compounds that activate JAKs to directly activate these pathways for improving fertility without triggering the OB-R. 
     EXAMPLE: MOLECULAR CLONING OF OB-R VARIANTS 
     A number of cDNA clones were isolated from a human fetal liver cDNA library (Clontech, Palo Alto, Calif.), and the DNA sequences of several of these clones were determined. These clones (designated as Hu-B1.219 #4, #33, #34, #1, #3, #8, #36, #55, #57, #60 and #62) contained overlapping sequences, which were then compiled into a contiguous nucleotide sequence referred to as Hu-B1.219. When the deduced amino acid sequence of one such sequence (FIGS. 1A-1E) was compared with the sequence of a recently published human OB-R (Tartaglia et al., 1995, Cell 83:1263), they were shown to be nearly identical in the extracellular domains with the exception of three amino acids, whereas there existed extensive diversity in their intracellular cytoplasmic domains at the 3&#39; end. This sequence encodes an OB-R variant herein referred to as Form 1. In addition, two other variants were identified, and they both differ from the human OB-R published by Tartaglia et al (1995, Cell 83:1263) in their 3&#39; ends (FIG. 2). These two additional variants are referred to as Forms 2 and 3 of OB-R. The predicted protein sequences of the variants (FIGS. 3A-3D) contain two FN III domains, each containing a &#34;WS box&#34;, which are characteristic of genes of the Class I cytokine receptor family. 
     When various human tissue RNA were probed with a fragment containing a sequence commonly shared by the OB-R variants by Northern blot analysis, expression was detected in heart, placenta, lung, liver, muscle, pancreas, prostate, ovary, small intestine and brain (Table I). 
     Based on the sequence presented in FIGS. 1A-1E, the translation initiation site appears at position #97. The sequences of Forms 1, 2 and 3 encode an open reading frame up to and including nucleotide #2970, #2814 and #2784 (FIG. 2), respectively. It is believed that the sequence between nucleotides #2629 and #2682 (FIGS. 1A-1E) encodes a transmembrane domain. The complete sequences of Forms 1, 2 and 3 encode proteins of 958, 906 and 896 amino acids, respectively.

     The sequences of the three OB-R variants are identical to the sequence of human OB-R reported by Tartaglia (1995, Cell 83:1263-1271) in the transmembrane region and a portion of the intracellular domain up to and including nucleotide #2769 (FIG. 2), then they diverge at nucleotide #2770 and beyond. In addition, the products of these cDNA are substantially shorter in their intracellular domain than the human OB-R published by Tartaglia et al. These isoforms of OB-R may derive from a common precursor mRNA by an alternative splicing mechanism. The sequence in this region is consistent with well known splice junctions. It is noteworthy that the DNA sequence of Form 1 (FIGS. 1A-1E) of the OB-R variant from nucleotide #2768 to the end is 98% identical to a human retrotransposon sequence that is thought to be derived from a human endogenous retroviral DNA sequence (Singer, 1982, Cell 28:433; Weiner et al., 1986, Ann. Rev. Biochem. 55:631; Lower et al., 1993, Proc. Natl. Acad. Sci. USA 90:4480; Ono et al., 1987, Nucl. Acid. Res. 15:8725-8735). 
     EXAMPLE: EXPRESSION OF OB-R IN SEX HORMONE PRODUCING CELLS IN TEE OVARY AND DETECTION OF LEPTIN IN OVARIAN FOLLICULAR FLUIDS 
     MATERIALS AND METHODS 
     REVERSE TRANSCRIPTION/POLYMERASE CHAIN REACTION (RT/PCR) 
     Total RNA was isolated using standard laboratory procedures (Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Laboratory, N.Y.). Approximately 1 μg of total RNA was reverse transcribed and the cDNA was amplified by PCR (Perkin Elmer, Norwalk, Conn.). The PCR amplification conditions were: 94° C. for 30 sec, 60° C. for 30 sec, 72° C. for 30 sec for a total of 40 cycles. The amplified products were resolved by agarose gel electrophoresis and visualized by ethidium bromide staining. The OB-R amplimers were GGTTTGCATATGGAAGTC (upper) (SEQ ID NO:13) and CCTGAACCATCCAGTCTCT (lower) (SEQ ID NO:14). The Form 1 specific amplimers were GACTCATTGTGCAGTGTTCAG (upper) (SEQ ID NO:15) and TAGTGGAGGGAGGGTCAGCAG (lower) (SEQ ID NO:16). 
     RESULTS 
     Table I in Section 6, supra, shows that the OB-R is expressed in reproductive organs such as ovary and prostate gland. In order to determine the specific cell types in the ovary that expressed the receptor, primary granulosa and cumulus cell cultures were established from the ovaries and assayed for OB-R expression by RT/PCR. In Table II, the cells that produced sex hormones in the ovary, i.e. granulosa and cumulus cells, expressed the different forms of OB-R.

     Additionally, ovarian follicular fluids were obtained from several patients and assayed for the presence of leptin. The detection assay utilized an interleukin-3-dependent cell line, BaF3, that had been transfected with a chimeric receptor construct containing the extracellular domain of murine OB-R ligated to the transmembrane and cytoplasmic domains of the thrombopoietin receptor. Both the BaF3 parental cell line and the transfected cell line responded to IL-3, whereas only the transfected cells responded to leptin (FIG. 4). 
     When the cells were incubated with follicular fluids, the transfected cell line was induced to proliferate as compared with the parental cell line as a control (FIG. 4). The cell growth-stimulating activity in the fluids was shown to be leptin since the activity was specifically inhibited by the addition of soluble murine OB-R (FIG. 5). Therefore, leptin is present in the follicular fluids, and it stimulates OB-R-expressing cells in the ovary to proliferate.
