Disease[PPARG_HUMAN] Note=Defects in PPARG can lead to type 2 insulin-resistant diabetes and hyptertension. 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.[1] 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.[2] [3] 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.[4] [5] [6] Publication Abstract from PubMedA series of benzimidazolone carboxylic acids and oxazolidinediones were designed and synthesized in search of selective PPARgamma modulators (SPPARgammaMs) as potential therapeutic agents for the treatment of type II diabetes mellitus (T2DM) with potentially improved safety profiles relative to rosiglitazone and pioglitazone, the currently marketed PPARgamma full agonist drugs. Structure-activity relationships of these potent and highly selective SPPARgammaMs were studied with a focus on their unique profiles as partial agonists or modulators. A variety of methods, such as X-ray crystallographic analysis, PPARgamma transactivation co-activator profiling, gene expression profiling and mutagenesis studies, were employed to reveal the differential interactions of these new analogs with the PPARgamma receptor in comparison to full agonists. In rodent models of T2DM, benzimidazolone analogs such as (5R)-5-(3-{[3-(5-methoxybenzisoxazol-3-yl)benzimidazol-1-yl]methyl}phenyl) -5-methyloxazolidinedione (51) demonstrated equivalent efficacy to rosiglitazone. Side effects, such as fluid retention and heart weight gain associated with PPARgamma full agonists, were diminished with 51 in comparison to rosiglitazone based on studies in two independent animal models.
