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, ppar gamma, where little gene expression was noted. In addition, PPAR gamma is present at low levels in 3T3-L1 preadipocytes and is induced ppar gamma 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. NRs are multi-domain ligand-inducible transcription factors that share a structural homology to a varying extent 8.

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. For example, the phosphorylation of serine will inhibit PPARG function, and enhance adipogenic potential of fibroblasts. PPARG regulates fatty acid storage and glucose metabolism. PPARG increases insulin sensitivity by enhancing storage of fatty acids in fat cells reducing lipotoxicity , by enhancing adiponectin release from fat cells, by inducing FGF21 , [12] and by enhancing nicotinic acid adenine dinucleotide phosphate production through upregulation of the CD38 enzyme. Many naturally occurring agents directly bind with and activate PPAR gamma. These agents include various polyunsaturated fatty acids like arachidonic acid and arachidonic acid metabolites such as certain members of the 5-hydroxyicosatetraenoic acid and 5-oxo-eicosatetraenoic acid family, e. PPARG agonists inhibit extravillous cytotrophoblast invasion. PPARG is also required for the accumulation of lipid droplets by the placenta. Peroxisome proliferator-activated receptor gamma has been shown to interact with:. PPAR-gamma agonists have been used in the treatment of hyperlipidaemia and hyperglycemia. Many insulin sensitizing drugs namely, the thiazolidinediones used in the treatment of diabetes activate PPARG as a means to lower serum glucose without increasing pancreatic insulin secretion.

Federal government websites often end in. The site is secure. Thus, PPAR family of nuclear receptors plays a major regulatory role in energy homeostasis and metabolic function. 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.
