What is the function of PPAR-alpha?
Abstract. Peroxisome proliferator-activated receptor (PPAR)-alpha is a ligand-activated transcriptional factor that belongs to the family of nuclear receptors. PPAR-alpha regulates the expression of genes involved in fatty acid beta-oxidation and is a major regulator of energy homeostasis.

A clinical trial of the PPAR-α agonist, gemfibrozil, showed a significant reduction of serum triglyceride, a significant increase in serum HDL cholesterol and lower incidence of coronary death and nonfatal myocardial infarction in patients with mild to moderate CKD and coronary disease and low HDL cholesterol level.
How do PPAR-alpha agonists work?
PPAR agonist drugs enhance PPAR activities. Fenofibrate (TricorTM) and Bezafibrate (BezalipTM) are mostly known as PPAR-α agonists for treating dyslipidemia by reducing triglycerides (TG) and free fatty acids (FFA) and increasing the levels of high-density lipoproteins (HDL).

PPAR-alpha is highly expressed in hepatocytes, cardiomyocytes, enterocytes, and the proximal tubule cells of kidney. PPAR-beta is expressed ubiquitously and often at higher levels than PPAR-alpha and -gamma.

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.

Tissue distribution
In rodents, highest mRNA expression levels of PPAR-alpha are found in liver and brown adipose tissue, followed by heart and kidney. Lower PPAR-alpha expression levels are found in small and large intestine, skeletal muscle and adrenal gland.

The clinical use of the PPAR-γ agents pioglitazone and rosiglitazone revealed a number of common adverse effects, including weight gain, fluid retention, congestive heart failure, and bone fractures (15, 16), suggesting that these effects are likely PPAR-γ dependent (17).
What do PPARs do?
Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors of nuclear hormone receptor superfamily comprising of the following three subtypes: PPARα, PPARγ, and PPARβ/δ. Activation of PPAR-α reduces triglyceride level and is involved in regulation of energy homeostasis.

Fibrates stimulate cellular fatty acid uptake, conversion to acyl-CoA derivatives, and catabolism by the -oxidation pathways, which, combined with a reduction in fatty acid and triglyceride synthesis, results in a decrease in VLDL production.

What is PPARs function?
PPARs form heterodimers with retinoic X receptors, and upon ligand binding, they modulate the gene expression of downstream target genes, depending on the presence of co-repressors or co-activators. This results in a complex, cell type-specific regulation of proliferation, differentiation, and cell survival.
What are the benefits of PPARs?
Treatment with PPAR agonists can reduce the burden of atherogenic postprandial lipoproteins and improve vascular function, reduce inflammation and inhibit foam cell formation. All of these would be expected to have favorable effects on cardiovascular risk.
What activates PPAR?
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.
Do fibrates activate PPAR?
Fibrates activate specific transcription factors belonging to the nuclear hormone receptor superfamily, termed peroxisome proliferator-activated receptors (PPARs).
What is the difference between statins and fibrates?
Statins lower LDL-cholesterol (LDL-C), with limited effects on other lipid parameters. Fibrates improve atherogenic dyslipidemia characterized by high triglyceride and/or low HDL-C levels and elevated concentrations of small dense LDL particles, with or without high LDL-C levels.
Which drug activates PPAR gamma?
Pioglitazone and rosiglitazone directly activate PPARγ, and their complex bind to PPRE in the adiponectin promoter (Iwaki et al., 2003). In fact, treatment with PPARγ agonists has been shown to increase circulating adiponectin levels by approximate 2- to 3-fold in patients (Tonelli et al., 2004; Yang et al., 2002).
How does PPAR gamma work?
Activation of PPAR-γ causes insulin sensitization and enhances glucose metabolism, whereas activation of PPAR-β/δ enhances fatty acids metabolism. Thus, PPAR family of nuclear receptors plays a major regulatory role in energy homeostasis and metabolic function.
When should I take PPAR?
Pioglitazone tablets are taken orally once daily with or without food. Initially 15-30 mg once daily increased to 45 mg once daily according to response. The dose may be increased in increments up to 45 mg once daily or as prescribed by the physician.
