Ppar gamma

PPARG is mainly present in adipose tissuecolon and macrophages.

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.

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.

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.

In the field of molecular biology , the peroxisome proliferator—activated receptors PPARs are a group of nuclear receptor proteins that function as transcription factors regulating the expression of genes. Three types of PPARs have been identified: alpha, gamma , and delta beta : [4]. These agents, pharmacologically related to the fibrates were discovered in the early s. PPARs were originally identified in Xenopus frogs as receptors that induce the proliferation of peroxisomes in cells in The best-known PPAR ligands are the thiazolidinediones. PPARs were so-named because they were discovered to induce peroxisome proliferation in rodents, but this induction of peroxisome proliferation is not believed to occur in humans. In general, this sequence occurs in the promoter region of a gene , and, when the PPAR binds its ligand, transcription of target genes is increased or decreased, depending on the gene.
