What activates peroxisome proliferator?

PPARs are activated by endogenous ligands that are derived from the metabolism of fatty acids and other compounds that are found in the diet, which is consistent with the fact that PPARs regulate the expression of many genes involved in glucose and lipid metabolism1.

Where do the peroxisome proliferator-activated receptors PPARs reside in cells?

Peroxisome proliferator-activated receptors are expressed in many tissues, including adipocytes, hepatocytes, muscles and endothelial cells; however, the affinity depends on the isoform of PPAR, and different distribution and expression profiles, which ultimately lead to different clinical outcomes.

What is the meaning of peroxisome proliferator?

Peroxisome proliferators (PPs) are a diverse group of chemicals with dissimilar structures capable of producing pleiotropic responses in experimental animals. These are classified as nongenotoxic carcinogens but are prolific inducers of rodent liver cancer when administered chronically.

What drug is a ligand of peroxisome proliferator-activated receptor gamma?

Hypolipidemic drugs, polyunsaturated fatty acids, and eicosanoids are ligands for peroxisome proliferator-activated receptors α and δ

What happens when PPAR is activated?

Activation of PPAR-α reduces triglyceride level and is involved in regulation of energy homeostasis. Activation of PPAR-γ causes insulin sensitization and enhances glucose metabolism, whereas activation of PPAR-β/δ enhances fatty acids metabolism.

Which anti diabetic drug is acting through nuclear peroxisome proliferator activated receptor agonism?

Thiazolidinediones (TZDs) are another type of insulin-sensitizing drug which act by binding peroxisome proliferator-activator nuclear receptor (PPAR)-γ, a transcription factor which is abundant in adipose cells.

Which anti diabetic drug is acting through nuclear peroxisome proliferator-activated receptor agonism?

What is the role of PPAR?

PPAR are involved in various independent and DNA-dependent molecular and enzymatic pathways in adipose tissue, liver, and skeletal muscles. These pathways are affected in disease condition and cause the metabolic energy imbalance.

Which drug binds to the peroxisome proliferator-activated receptor gamma in adipose tissue muscle and liver?

Thiazolidinediones (TZDs) agonists for peroxisome proliferators-activated receptor (PPAR) γ are currently used therapeutically. Troglitazone, the first agent of this class to be approved, was effective in controlling glycemia but was removed from the market because of serious liver toxicity.

What are peroxisome proliferator activated receptors (PPARs)?

Peroxisome proliferator activated receptors (PPARs) are intracellular ligand-activated transcription factors and part of the nuclear receptor superfamily. PPARs are divided into three subtypes, which can give rise to pro- or anti-inflammatory outcomes.

What is the mechanism of action of peroxisome proliferators?

MECHANISM OF ACTION OF PEROXISOME PROLIFERATOR-ACTIVATED RECEPTORS PPARs function as heterodimer in association with co- activator complex that binds to DNA sequence termed peroxisome proliferators response elements (PPREs) present in promoter of target genes which leads to transactivation and transrepression of various genes.[1]

Do PPAR-α activators regulate obesity in rodents?

PPAR-α activators have been shown to regulate obesity in rodents by both increasing hepatic FA oxidation and decreasing the levels of circulating triglycerides responsible for adipose cell hypertrophy and hyperplasia.

What is the role of PPAR-δ in the etiology of atherogenesis?

PPAR-δ has been noted to reduce the expression of inflammatory mediators and adhesion molecules, suggesting their potential role in attenuating atherogenesis.[22]
