The present invention provides methods of treating and preventing cardiac hypertrophy and heart failure. MEF-2, NF-AT3, calcineurin, MCIP, and Class II HDACs have been shown to have a major role in cardiac hypertrophy and heart disease, and inhibition of many of these factors or the pathways mediated by these factors has been shown to have a beneficial, anti-hypertrophic effect. The present invention provides a link between these factors and the pathways they mediate through a family of non-voltage gated channels called TRP channels. The present invention further demonstrates that inhibitors of TRP channels can inhibit or treat heart failure and cardiac hypertrophy.

Provided are methods and compositions for maintaining the viability of photoreceptor cells following retinal detachment. The viability of photoreceptor cells can be preserved by administering a neuroprotective agent, for example, a substance capable of suppressing endogenous calcineurin or constitutively active calcineurin, inhibiting cleavage of calcineurin to constitutively active calcineurin, and/or directly or indirectly antagonizing calcineurin or constitutively active calcineurin (and combinations thereof), to a mammal having an eye with retinal detachment. The neuroprotective agent maintains the viability of the photoreceptor cells until such time that the retina becomes reattached to the underlying retinal pigment epithelium and choroid. The treatment minimizes the loss of vision, which otherwise may occur as a result of retinal detachment.

In accordance with the present invention, it has been discovered that glucose and incretin hormones promote pancreatic islet cell survival via the calcium and cAMP dependent induction, respectively, of the transcription factor CREB. Specifically, a signaling module has been identified which mediates cooperative effects of calcium and cAMP on islet cell gene expression by stimulating the dephosphorylation and nuclear entry of TORC2, a cytoplasmic CREB coactivator. The module comprises a cAMP regulated snf1-like kinase called SIK2 and the calcium regulated phosphatase calcineurin, both of which associate with TORC2 in the cytoplasm. TORC2 is repressed under basal conditions through a phosphorylation dependent interaction with 14-3-3 proteins. cAMP and calcium signals stimulate CREB target gene expression via complementary effects on TORC2 dephosphorylation; cAMP disrupts TORC2-associated activity of SIK2 or related family members, whereas calcium induces TORC2 dephosphorylation via calcineurin. These findings provide a novel mechanism by which CREB activates cellular gene expression, depending on nutrient and energy status, and facilitate development of assays to identify compounds which modulate the role of TORCs. In accordance with the present invention, it has been discovered that fasting and energy-sensing pathways regulate the gluconeogenic program in liver by modulating the nuclear entry of a transcriptional coactivator called Transducer of Regulated CREB Activity 2 (TORC2). Hepatic TORC2 over-expression induces fasting hyperglycemia, whereas knockdown of TORC2 leads to fasting hypoglycemia and silencing of the gluconeogenic program. Since a majority of individuals with Type II diabetes exhibit fasting hyperglycemia due to elevated hepatic gluconeogenesis, compounds that enhance TORC2 phosphorylation will find use as therapeutic agents in this setting.

Therapeutic compositions for treatment of protein serine/threonine phosphatase-related diseases are obtained by engineering amino acid sequences that disrupt interaction between the protein serine/threonine phosphatase and a protein inhibitor and are provided herein. Calcineurin and PPI are examples of protein serine/threonine phosphatases. RCAN1 is an inhibitor of calcineurin and is overexpressed in patients with serious diseases, such as Down syndrome and Alzheimer's disease. Molecules that bind RCAN1 at regions that interact with calcineurin selectively modulate functions of calcineurin to treat these diseases. Methods of treating a subject for a protein serine/threonine phosphatase-related disease by administering a molecule having an amino acid sequence selected from the group of SEQ ID NOs: 1-19 are further provided.

A previously unknown T cell receptor (TCR) activation pathway dependent on the aryl hydrocarbon receptor conferring resistance to calcineurin inhibitors and mTOR inhibitors is disclosed, including application of this pathway to the diagnosis and treatment of certain disease states refractory to treatment with calcineurin inhibitors. This alternative TCR activation pathway uniquely exists in a subset of CD8 T cells expanded in the setting of chronic rejection or rheumatoid arthritis. Expansion of this newly discovered calcineurin and mTOR inhibitor resistant CD8 T cell subset in humans can be quantified by measuring levels of certain biomarkers in the circulating CD8 T cell pool, such as Pla2g4a, to diagnose disease states mediated thereby. Additionally, methods for diagnosing ongoing active inflammation mediated by this resistant CD8 T cell subset in either chronic rejection or rheumatoid arthritis are provided, which comprise measuring levels of the biomarker Scin in the circulating CD8 T cell pool.
