     BACKGROUND 
     Ischemia is a condition wherein the blood flow is completely obstructed or considerably reduced in localized parts of the body, resulting in anoxia, reduced supply of substrates and accumulation of metabolites. Prolonged ischemia results in atrophy, denaturation, apoptosis, and necrosis of affected tissues. 
     Inflammation is a protective response that is intended to eliminate an initial cause of an injury, as well as necrotic cells/tissues resulting from the injury. In some diseases, such as arthritis, however, inflammation occurs in the absence of an injury. Prolonged inflammation can cause tissue destruction, fibrosis, and/or necrosis. 
     The goal of regenerative medicine is to induce healing and prevent fibrosis and scar formation following injury through replacement of damaged tissues and induction of endogenous repair pathways. 
     SUMMARY 
     Disclosed herein are methods of treating an ischemic or inflammatory condition in an organ or tissue of a patient, comprising inducing an increase of the level of CAMKK1 in said organ or tissue.

     The term “patient” as used herein is intended to mean any animal, in particular, mammals. Thus, the methods are applicable to human and nonhuman animals, although preferably used with mice, rats, and humans, and most preferably with humans. 
     As used herein, “an increase of the level of CAMKK1” means an amount of CAMKK1 protein in the organ or tissue of the patient that is greater than what is normally present in the organ or tissue of the patient. 
     Disclosed herein are methods of treating an ischemic or inflammatory condition in an organ or tissue of a patient, comprising inducing an increase of the level of CAMKK1 in said organ or tissue. 
     CAMKK1 (calcium/calmodulin-dependent protein kinase kinase 1; human CAMKK1 known by UniProtKB number Q8N5S9) belongs to a calcium-triggered signaling cascade and is involved in a number of cellular processes. CAMKK1 is a transferase that belongs to Ser/Thr protein kinase family and CamKK subfamily, and is expressed in heart, pancreas, amygdale, hypothalamus, prostate and lung. CAMKK1 activates CamK1 and CamK4 by phosphorylation of their amino acids Thr(177) and Thr(196), respectively. CAMKK1 activity is itself subjected to regulation by Ca2+/calmodulin; the activity of CAMKK1 is decreased upon phosphorylation by PKA (cAMP-Dependent Protein Kinase) and increased by incubation with PKA in the presence of Ca(2+)/calmodulin but decreased in its absence. This phosphorylation and inhibition of CAMKK1 by PKA is involved in modulating the balance between cAMP- and Ca2+-dependent signal transduction pathways. The nucleic acid sequence and amino acid sequence of CAMKK1 is set forth in SEQ ID NOs:1 and 2, respectively. 
     Those skilled in the art know that ischemic conditions and inflammatory conditions can occur in a number of different organs in tissues. For example, ischemic conditions can occur in the heart, liver, kidney, brain, spine, lungs, small intestine, large intestine, and arteries. Likewise, inflammatory conditions can occur in the heart, liver, kidney, brain, spine, lungs, intestines, arteries, joints, cartilage, and skin. Accordingly, disclosed are methods of treating an ischemic or inflammatory condition in an organ or tissue of a patient, wherein said organ or tissue is heart, liver, kidney, brain, spine, lungs, small intestine, large intestine, arteries, joints, cartilage, skin, or any combination thereof. In some embodiments, the methods can be used to treat an ischemic or inflammatory condition in the heart. In some embodiments, the methods can be used to treat an ischemic or inflammatory condition in the myocardium. In some embodiments, the methods can be used to treat an ischemic or inflammatory condition in the liver.

     Suitable techniques for increasing the level of CAMKK1 in an organ or tissue include, but are not limited to, administering CAMKK1 protein, administering a vector comprising a nucleic acid encoding CAMKK1, administering cells that have been modified to produce an increased level of CAMKK1, administering conditioned media from a culture of cells that have been modified to have an increase of the level of CAMKK1, or any combination thereof. 
     The increase in the level of CAMKK1 in said organ or tissue can be achieved, for example, by administering CAMKK1 protein to said organ or tissue. Suitable CAMKK1 proteins include wild type CAMKK1 or a constitutively active CAMKK1. In some aspects, the increase in the level of CAMKK1 in said organ or tissue can be achieved by administering wild type CAMKK1 protein to said organ or tissue. For example, the increase in the level of CAMKK1 in said organ or tissue can be achieved by administering wild type CAMKK1 protein to said organ or tissue, wherein the wild type CAMKK1 protein is set for in SEQ ID NO:2. In other aspects, the increase in the level of CAMKK1 in said organ or tissue can be achieved by administering a constitutively active CAMKK1. The constitutively active CAMKK1 can comprise a CAMKK1 1-413 truncation. The increase in the level of CAMKK1 in said organ or tissue can be achieved by administering a CAMKK1 1-413 truncation to said organ or tissue, wherein the CAMKK1 1-413 truncation is set forth in SEQ ID NO:4. Alternatively, the constitutively active CAMKK1 can comprise a T108A mutant, a S459A mutant, or a T108A/S459A mutant CAMKK1. The increase in the level of CAMKK1 in said organ or tissue can be achieved by administering a T108A mutant CAMKK1 to said organ or tissue, wherein the T108A mutant CAMKK1 is set forth in SEQ ID NO:6. The increase in the level of CAMKK1 in said organ or tissue can be achieved by administering a S459A mutant CAMKK1to said organ or tissue, wherein the S459A mutant CAMKK1 is set forth in SEQ ID NO:8.

Therefore, construction of a constitutively active and non phosphorylatable CAMKK1 by removing one or more of these residues (through, for example, truncation) or mutating Thr108 and Ser459 to alanine, for example, may result in a more potent therapeutic. 
     The increase in the level of CAMKK1 in said organ or tissue can be achieved by administering a vector comprising a nucleic acid encoding CAMKK1 to said organ or tissue. The vector can comprise a plasmid or a viral vector. In some aspects, the increase in the level of CAMKK1 in the organ or tissue can be achieved by administering a plasmid comprising a nucleic acid encoding CAMKK1. In other aspects, the increase in the level of CAMKK1 in the organ or tissue can be achieved by administering a viral vector comprising a nucleic acid encoding CAMKK1. The nucleic acid can encode wild type CAMKK1 or a constitutively active CAMKK1. In some aspects, the increase in the level of CAMKK1 in the organ or tissue can be achieved by administering a plasmid or viral vector comprising a nucleic acid encoding wild type CAMKK1. For example, the increase in the level of CAMKK1 in the organ or tissue can be achieved by administering a plasmid or viral vector comprising CAMKK1 as set forth in SEQ ID NO:1.

Such other components include, for example: components that influence binding or targeting to cells (including components that mediate cell-type or tissue-specific binding); components that influence uptake of the vector by the cell; components that influence localization of the nucleic acid within the cell after uptake (such as agents mediating nuclear localization); and components that influence expression of the nucleic acid. Such components can be provided as a natural feature of the vector (such as the use of certain viral vectors which have components or functionalities mediating binding and uptake), or vectors can be modified to provide such functionalities. Such components also include markers, such as detectable and/or selectable markers that can be used to detect or select for cells that have taken up and are expressing the nucleic acid delivered by the vector. Selectable markers include, for example, ampicillin and kanamycin. In some aspects, the selectable marker can be removed from the vector. 
     Suitable viral vectors include, but are not limited to, those derived from adenovirus (Ad), adeno-associated virus (AAV), herpes simplex virus (HSV), retrovirus, lentivirus, and alphavirus. Both human and non-human viral vectors can be used. In embodiments wherein human viral vectors are used, the viral vector can be modified to be replication-defective in humans. 
     The vector comprising a nucleic acid encoding CAMKK1 can be under a constitutively active promoter, a tissue specific promoter, or a drug inducible promoter. For example, a tissue-specific promoter can be fused to the nucleic acid encoding CAMKK1, limiting its expression to a particular tissue. 
     The nucleic acid encoding CAMKK1 can be introduced into the cells by techniques known in the art including, but not limited to, transfection and electroporation. The vector may be modified to improve transfection or electroporation efficiency.

     EXAMPLES 
     The following examples are provided to further describe some of the embodiments disclosed herein. The examples are intended to illustrate, not to limit, the disclosed embodiments. 
     Pretreatment of MSCs with the growth factor transforming growth factor beta (TGF-β) increased the immune suppressive and proangiogenic activity of the cells and resulted in enhanced regenerative capacity ( FIG. 2 ). In a rodent model of AMI, conditioned media collected from TGF-β treated MSCs was delivered to the heart. Improved cardiac function was noted as compared to delivery of conditioned media from untreated MSCs. 
     Following receptor binding, TGF-β treatment of MSCs cells resulted in a decrease in the expression of disabled homolog 2 (Dab2), a TGF-β1 receptor adaptor protein, that is mediated by an increase in microRNA miR145 ( FIG. 3 ). Decreasing Dab2 expression in MSCs using siRNA also resulted in improved benefit in cardiac function from conditioned media collected from transfected cells ( FIG. 2 ) compared to conditioned media from untreated MSCs when delivered to the heart in a rodent model of AMI. The levels of specific chemokines and growth factors in control and Dab2:siRNA transfected MSC were compared and no differences in FGF-2, PDGF-b, IGF-1, SDF-1 or SFRP-2 were observed (data not shown). 
     In order to identify the molecular mechanisms which lead to the enhanced secretome of MSCs, an Illumina gene array screen was performed to identify gene changes in response to three different mechanisms of Dab-2 down-regulation: TGF-β treatment, transfection with miR145 and transfection with siRNA against Dab2 compared with untreated cells. In this experiment, cRNA samples from treated cells (TGF-β, mir145, or siRNA Dab2) or untreated cells were hybridized to the Illumina Rat-Ref12 expression BeadChip. 
     Briefly, the labeled cRNA samples were hybridized to the Illumina RatRef-12 expression BeadChip, which was scanned using Illumina Beadstation GX (Illumina, San Diego, Calif., USA). Each BeadChip contains 22,523 probes that were selected from the National Center for Biotechnology Information (NCBI) Reference Sequence (RefSeq) database. The microarray image was analyzed and intensity data were normalized using Illumina Beadstudio software (Illumina, San Diego, Calif., USA). 
     To select differentially expressed genes, Welch two sample t-test was performed. The results were combined with fold change and detection p-values to identify differentially expressed genes. Specifically, the selection criterions include the sum of the detection p-values for the three repeats being less than or equal to 0.1, average p-values less than or equal to 0.05, and fold change between control and treated samples greater than or equal to 1.5. In addition, set operations were performed to identify commonly deregulated molecules. 
     Following the identification of differentially expressing genes, the dataset containing these genes and the corresponding expression values was uploaded into the Ingenuity Systems Pathway Analysis (IPA) software (Ingenuity Systems, Redwood City, Calif.). TGFβ1, miR-145 and Dab2 as well as these differentially expressed genes were marked as focus molecules in IPA. The focus molecules served as seeds and their relationships with other molecules in the Ingenuity Knowledge Base were identified and presented in a set of networks (directed graphs) in which the biological relationship between two molecules (nodes) is represented as a directed edge. In addition, functional and canonical pathway analyses were carried out using IPA. The focus molecules and their closely related genes were analyzed and over-represented functional groups and canonical pathways were identified. Significance of association between these genes and a functional group or a canonical pathway was measured using the p value obtained using Fisher&#39;s exact test determining the probability that the association between the focus molecules and the group/pathway is explained by chance alone. A cutoff threshold of 0.05 was used in this study. 
     Twenty-three (23) common significant (p&lt;0.05) differentially expressed genes (&gt;1.5 fold difference) were identified from the treated cells compared to the untreated cells (Table 1). Pathway analysis identified one gene, calcium/calmodulin-dependent protein kinase kinase 1 (CAMKK1), downstream of miR145, TGF-β signaling and dab-2 downregulation, that is shown herein to modulate the MSC secretome and function. An independent experiment confirmed that downregulation of Dab2 results in upregulation of CAMKK1 expression and associated with an upregulation in CAMKK1 protein ( FIG. 4 ).

     Real-time PCR was performed to confirm that the down-regulation of Dab2 leads to up-regulation of CAMKK1 from MSC in culture (data not shown). Western blot analysis confirmed that this up-regulation was associated with an increase in CAMKK1 protein expression (data not shown). 
     CAMKK1 has not previously been demonstrated to be involved in inducing or enhancing endogenous regenerative pathways. To demonstrate the role of CAMKK1 in modulating the MCS secretome, CAMKK1 expression was downregulated in MSCs through transfection with CAMKK1 siRNA. The data in  FIG. 5A  show that the injection of 2 million MSC or the concentrated condition media from 2 million MSC into the infarct border zone at the time of LAD ligation results in inhibition of MSC mediated preservation of left ventricular function, specifically, a 30% and 20% increase in cardiac function, respectively, 14 days after AMI. In the absence of CAMKK1, however, there is no significant increase in cardiac function in response to the injection of MSC or MSC conditioned media ( FIG. 5A ). To begin to understand how the absence of CAMKK1 altered myocardial response to MSC injection, the area of collagen deposition and vascular density in response to MSC and MSC conditioned media injections was quantified. An increase in collagen deposition ( FIG. 5B ) and a blunting in the increase in vascular density ( FIG. 5C ) was observed in response to MSC transfected with CAMKK1:siRNA compared to control MSC. These data demonstrate that modulation of CAMKK1 does alter the MSC secretome and subsequent myocardial repair through potentially multiple mechanisms. Importantly, the down-regulation of CAMKK1 in TGF-β1 pretreated MSC also rendered the conditioned from these cells inactive (data not shown). 
     To begin to define paracrine factors that are modulated by CAMKK1 expression in MSC, conditioned media from MSC transfected with scramble or CAMKK1:siRNA was assayed. The media was conditioned for 24 hours, beginning 24 hours after transfection. The media was concentrated as though for intracardiac injection. The concentrated conditioned media was assayed using a nylon based cytokine array. Consistent with the hypothesis that up-regulation of CAMKK1 is pro-healing, down-regulation of CAMKK1 resulted in the up-regulation of 5 cytokines, 4 of which are related to inflammatory cell recruitment. 
     To test whether activation of the CAMKK1 pathway can result in enhanced regenerative capacity of other cells types, a plasmid encoding CAMKK1 downstream of the CMV promoter was developed and utilized to demonstrate that upregulation of CAMKK1 activity can result in improved cardiac function. Following induction of an AMI in rodents by LAD ligation, CAMKK1 encoding plasmid (KCP-CAMKK1) or vehicle was injected directly into the heart into the peri-infarct area. Cardiac function was measured 1 week and 2 weeks later and resulted in improvement in cardiac function as measured by echocardiography in KCP-CAMKK1 treated animals compared to vehicle (saline or glucose) treated animals ( FIG. 6 ). Taken together, the data demonstrate that activation of CAMKK1 signaling pathway through overexpression of CAMKK1 results in enhanced regeneration in the heart. 
     To determine if the up-regulation of CAMKK1 was sufficient to induce tissue repair, studies with control and CAMKK1 over-expressing MSC and conditioned media from control and CAMKK1 over-expressing MSC were performed. The data in  FIG. 8A  and  FIG. 8B  demonstrate that the over-expression of CAMKK1 in MSC enhanced MSC and MSC conditioned media function in AMI. 
     Whether CAMKK1 over-expression in the absence of MSC could lead to MSC like effects on the left ventricle in the setting of AMI was evaluated by generating a cDNA expression vector that used the CMV promoter to overexpress CAMKK1. 5×100 ug injections of plasmid cDNA were delivered around the infarct border zone at the time of LAD ligation. LV function as a function of time after AMI was quantified. As shown in  FIG. 7  CAMKK1 over-expression in the absence of MSC led to significant preservation or recovery of LV function. 
     Histological analyses (data not shown) of the tissue at the end of the experiments displayed in  FIG. 5B  and C demonstrated that CAMKK1 consistently led to:
         a decrease in infarct size and myocardial fibrosis as measured by Mason&#39;s trichrome stain;   an increase in vascular density in the infarct border zone.       

     There is no effect of CAMKK1 on SDF-1, or SDF-1 on CAMKK1 expression (data not shown). The CAMKK1 approach appears to have the potential to be completely synergistic and not redundant to SDF-1. 
     SUMMARY 
     As disclosed herein, CAMKK1 was identified as a key regulator of MSC function. The fact that the SDF-1:CXCR4 axis and CAMKK1 have no molecular overlap with respect to induced expression suggests that a combination of CAMKK1 and SDF-1 should have synergistic effects, most obviously in acute injury, and likely in chronic tissue injury. 
     The disclosed methods induce the enhancement of the regenerative secretome (secreted molecules) from multiple cell types, including MSCs. Without intending to be bound by theory, it is believed that the increased levels of CAMKK1 result in enhanced functional benefit through alteration of secreted factors from those cells expressing CAMKK1. This secretome induction can be used as a novel regenerative therapeutic.
