Definition / general
- Peroxisome Proliferator Activated Receptor γ
- PAX8 / PPARγ fusion protein is produced by t(2;3)(q13;p25), occurs frequently in follicular thyroid carcinoma; diffuse strong nuclear staining correlates with PAX8-PPARγ detected by RT-PCR in follicular carcinoma or adenoma (Am J Surg Pathol 2002;26:1016)
- PPARγ agonist pioglitazone protects cortical neurons from inflammatory mediators via improvement in peroxisomal function, and may protect against neurodegenerative changes associated with neuroinflammation (J Neuroinflammation 2012;9:63, Mol Neurobiol 2012;46:114)
- Decreases inflammatory response of many cardiovascular cells, particularly endothelial cells
- Also blocks fibrogenic TGF-beta responses in vitro and in vivo (Arthritis Res Ther 2012;14:R102)
- Controls adipocyte differentiation and regulates many genes associated with energy homeostasis
- Its gene polymorphisms influence obesity and obesity phenotype in a complex manner, probably involving insulin resistance in north Indian population (Am J Hum Biol 2012;24:454)
Uses by pathologists
