PPARG


Also found in: Acronyms, Wikipedia.

PPARG

A gene on chromosome 3p25 that encodes a member of the nuclear receptor family of ligand-activated transcription factors, which heterodimerise with the retinoic X receptor (RXR) to regulate gene expression. PPARG binds peroxisome proliferators such as hypolipidaemic drugs and fatty acids, and controls the peroxisomal beta-oxidation pathway of fatty acids. It is a key regulator of adipocyte differentiation and glucose homeostasis.

Molecular pathology
Defects in PPARG mutation are linked to type-2 insulin-resistant diabetes and hypertension, obesity, glioma type 1, and cause familial partial lipodystrophy type 3.

PPARG

A gene with an allele that increases the risk of developing type 2 diabetes mellitus. People with this allele may benefit from treatment with thiazolidinedione drugs.

42-44] With the exception of LOC387761 and EXT2, these novel loci and 2 previously-known variants, PPARG P12A and KCNJ11 E23K, were confirmed by multiple replication studies composed of European and non-European populations.
The PPARG gene, encoding the nuclear receptor PPAR-[gamma], was the first gene reproducibly associated with T2D (21).
Therefore, FA with PAX8/ PPARG rearrangement needs thorough sampling of the specimen to rule out capsular and vascular invasion.
PPARG and FABP4 are reportedly key regulators in the PPAR signaling pathway associated with adipogenesis and marbling traits in beef cattle.
A similar fraction of follicular carcinomas, but a much smaller fraction of adenomas, are found to harbor a t(2;3)(q13; p25) chromosomal translocation that fuses the PAX8 [2] (paired box 8) gene with the PPARG (peroxisome proliferator-activated receptor gamma) gene (2).
AHR (aryl hydrocarbon receptor), PPARG, and CEBPB are all highly expressed in the placenta, which represents a potential MRDT target given its role as an endocrine organ (Scott et al.
21-24) Nikiforov et al (25) studied a 4-gene panel consisting of BRAF V600E, neuroblastoma RAS viral (v-ras) oncogene homlog (NRAS), Harvey rat sarcomal viral oncogene homolog (HRAS), and Kirsten rat sarcoma viral oncogene homolog (KRAS) point mutations, RET/PTC gene rearrangements, and PAX8/ PPARG gene rearrangement in 513 indeterminate aspirates with surgical follow-up.
Finally, the protein product of PAX8/ PPARG acts, at least in part, by inhibiting wild-type PPARG signaling (8), suggesting that such tumors could be amenable to PPARG agonist therapy, similar to what has been observed in anaplastic thyroid carcinoma (9).
The CEBPA and PPARG genes are important transcription factors involved in adipogenesis.
