Since its discovery in the early s by Tontonoz et al 1. The gene encompassed 9 exons exon A, exon B-D, and exons These isoforms lack the ligand binding domain LBD , which is due to alternative splicing. To date, 48 NRs have been identified in human. NRs regulate various critical aspects in development, physiology, reproduction, and homeostasis. NRs are multi-domain ligand-inducible transcription factors that share a structural homology to a varying extent 8.

Ppar gamma

Activators of peroxisome proliferator activated receptor PPAR regulate fatty acid metabolism and can induce adipocyte differentiation. We show here that the gamma subtype of PPAR is expressed at high levels in adipose tissue in contrast to a variety of other tissues, where little gene expression was noted. In addition, PPAR gamma is present at low levels in 3T3-L1 preadipocytes and is induced dramatically during adipocyte conversion using either normal differentiating conditions fetal calf serum, dexamethasone, isobutyl-methylxanthine, and insulin or the PPAR activator, WY, Thus PPAR gamma may be important for adipose cell development and function.

PPARG is mainly present in adipose tissue , colon and macrophages. This gene encodes a member of the peroxisome proliferator-activated receptor PPAR subfamily of nuclear receptors. The protein encoded by this gene is PPAR-gamma and is a regulator of adipocyte differentiation. Alternatively spliced transcript variants that encode different isoforms have been described. This modification decreases transcriptional activity of PPARG and leads to diabetic gene modifications, and results in insulin insensitivity.

The present review critically analyzes the protective and detrimental effect of PPAR agonists in dyslipidemia, diabetes, adipocyte differentiation, inflammation, cancer, lung diseases, neurodegenerative disorders, fertility or reproduction, pain, and obesity. Peroxisome proliferator-activated receptors PPARs proteins belong to superfamily of phylogenetically related protein termed nuclear hormone factor. But, these agents are associated with no proliferation in the human beings. Structurally, PPARs are similar to steroid or thyroid hormone receptor and are stimulated in response to small lipophilic ligands. In rodents, a large class of structurally related chemicals including herbicides, industrial solvents, and hypolipidemic drugs lead to significant increase in the number and size of peroxisomes in the liver and may cause liver hypertrophy, liver hyperplasia, hepatocarcinogenesis, and transcription of genes encoding proximal enzymes. The PPARs possess the canonical domain structure common to other nuclear receptor family members, including the amino-terminal AF-1 trans activation domain, followed by a DNA-binding domain, and a dimerization and ligand-binding domain with a ligand-dependent trans activation function AF-2 located at the carboxy-terminal region. PPARs are transcription factors that belong to the Superfamily of nuclear receptors.
