What is the Origin of PPARγ Dysregulation?

The term is derived from molecular endocrinology and pharmacology. PPARγ is an acronym for the receptor family, and "dysregulation" refers to a disturbance or failure of control in its normal biological activity. This receptor is the therapeutic target for a class of anti-diabetic drugs.

What is the Mechanism of PPARγ Dysregulation?

PPARγ acts as a ligand-activated transcription factor; upon binding specific fatty acids or pharmacological ligands, it heterodimerizes and moves to the nucleus to regulate the transcription of numerous metabolic genes. Dysregulation, often caused by chronic inflammatory signals or genetic polymorphisms, impairs its ability to promote the healthy, efficient storage of lipids in adipose tissue. This failure leads to the pathological deposition of fat in non-adipose organs like the liver and muscle, which directly precipitates systemic insulin resistance.

PPARγ Dysregulation

Meaning

PPARγ Dysregulation is a pathological state characterized by an impaired function, reduced expression, or altered activity of the Peroxisome Proliferator-Activated Receptor gamma, a nuclear receptor that serves as a master transcription factor for genes governing adipogenesis, lipid metabolism, and whole-body insulin sensitivity. Dysfunction of this receptor is a central molecular mechanism contributing to the development of insulin resistance, the metabolic syndrome, and type 2 diabetes.
