Abstract: The invention includes methods and compositions for treating a metabolic disorder, such as metabolic syndrome, hyperlipidemia and associated disorders, such as obesity and diabetes. The invention includes a method of treating a human subject comprising administering 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME) to the subject. The invention also includes methods and compositions for treating disorders and conditions that would benefit from skeletal muscle fatty acid uptake and oxidation, increased mitochondrial respiration in skeletal muscle and/or enhanced exercise capacity.

Abstract: The present invention is related to methods and compositions effective in regulating glycemic control in subject individuals in need of the regulation of glycemic control. Said individuals may have diabetes or be prediabetic condition receive therapeutically effective amounts of identified secreted proteins in an amount suitable for modulating glycemic control and to thereby treat or prevent diabetes in said subject.

Abstract: Deletion of the rsk2 gene in mice results in reduced body weight, reduced body fat and reduced sensitivity to diet-induced weight gain, as well as lower levels of leptin in the serum of rsk2 deficient mice and lower levels of oxygen consumption, as compared to wild type littermates. Thus, altering RSK2 activity provides a means for modulating RSK2-mediated signaling and therefore modulating the above described physiological parameters. The present invention encompasses methods and compositions for altering, or modulating in a mammal, body weight, fat content, leptin levels by altering, or modulating, RSK2 activity. Specifically encompassed in the present invention are methods and compositions to alter activity of the RSK2. The present invention is drawn to a model for the study of Coffin-Lowry syndrome as well as an in vivo model to screen and test therapeutic agents for the treatment of Coffin-Lowry syndrome.
