[https://www.uniprot.org/uniprot/PPARG_HUMAN 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:[https://omim.org/entry/601665 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.<ref>PMID:9753710</ref> Defects in PPARG are the cause of familial partial lipodystrophy type 3 (FPLD3) [MIM:[https://omim.org/entry/604367 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.<ref>PMID:12453919</ref> <ref>PMID:11788685</ref> Genetic variations in PPARG can be associated with susceptibility to glioma type 1 (GLM1) [MIM:[https://omim.org/entry/137800 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 ==
 +
[https://www.uniprot.org/uniprot/PPARG_HUMAN 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.<ref>PMID:9065481</ref> <ref>PMID:16150867</ref> <ref>PMID:20829347</ref>

== 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.
