PPARG mutations may be associated with colon cancer. Defects in PPARG may be associated with susceptibility to obesity (OBESITY) [MIM:601665. It is a condition characterized by an increase of body weight beyond the limitation of skeletal and physical requirements, as the result of excessive accumulation of body fat. Defects in PPARG are the cause of familial partial lipodystrophy type 3 (FPLD3) [MIM:604367. Familial partial lipodystrophies (FPLD) are a heterogeneous group of genetic disorders characterized by marked loss of subcutaneous (sc) fat from the extremities. Affected individuals show an increased preponderance of insulin resistance, diabetes mellitus and dyslipidemia. Genetic variations in PPARG can be associated with susceptibility to glioma type 1 (GLM1) [MIM:137800. Gliomas are central nervous system neoplasms derived from glial cells and comprise astrocytomas, glioblastoma multiforme, oligodendrogliomas, and ependymomas. Note=Polymorphic PPARG alleles have been found to be significantly over-represented among a cohort of American patients with sporadic glioblastoma multiforme suggesting a possible contribution to disease susceptibility. Function PPARG_HUMAN Receptor that binds peroxisome proliferators such as hypolipidemic drugs and fatty acids. Once activated by a ligand, the receptor binds to a promoter element in the gene for acyl-CoA oxidase and activates its transcription. It therefore controls the peroxisomal beta-oxidation pathway of fatty acids. Key regulator of adipocyte differentiation and glucose homeostasis. Acts as a critical regulator of gut homeostasis by suppressing NF-kappa-B-mediated proinflammatory responses. Publication Abstract from PubMed Selective peroxisome proliferator-activated receptor gamma (PPARgamma) modulators are expected to be a novel class of drugs improving plasma glucose levels without PPARgamma-related adverse effects. As a continuation of our studies for (-)-Cercosporamide derivatives as selective PPARgamma modulators, we synthesized substituted naphthalene type compounds and identified the most potent compound 15 (EC(50) = 0.94 nM, E(max) = 38%). Compound 15 selectively activated PPARgamma transcription and did not activate PPARalpha and PPARdelta. The potassium salt of compound 15 showed a high solubility and a good oral bioavailability (58%). Oral administration of the potassium salt remarkably improved the plasma glucose levels of female Zucker diabetic fatty rats at 1 mg/kg. Moreover, it did not cause a plasma volume increase or a cardiac enlargement in Wistar-Imamichi rats, even at 100 mg/kg.
