Members of the nuclear receptor superfamily have vital roles in regulating immunity and inflammation. The founding member, glucocorticoid receptor (GR), is the prototype to demonstrate immunomodulation via transrepression of the AP-1 and NF-κB signaling pathways. Peroxisome proliferator-activated receptors (PPARs) have emerged as key regulators of inflammation. This review examines the history ...

docosahexaenoic acid (dha), as an omega-3 fatty acid, in a natural ligand of peroxisome proliferator-activated receptors (ppars). regarding the combinative effects of nutrigenomics and nutrigenetics and due to the lack of in vivo studies conducted using natural ligands of ppars, we aimed to evaluate the effects of dha supplementation on vascular function, telomerase activity, and pparγ-lxrα-abc...

Solution- and solid-phase methods for the preparation of peptide-substituted thiazolidinediones have been developed as an approach towards the preparation of a library of these compounds as potential ligands for the peroxisome proliferator-activated receptors (PPARs).

The peroxisome proliferator-activated receptors (PPARalpha, PPARdelta, and PPARgamma) constitute a family of nuclear receptors that regulates metabolic processes involved in lipid and glucose homeostasis. Although generally considered to function as ligand-regulated receptors, all three PPARs exhibit a high level of constitutive activity that may result from their stimulation by intracellularly...

Non-alcoholic fatty liver disease (NAFLD) has been defined as a spectrum of histological abnormalities and is characterized by significant and excessive accumulation of triglycerides in the hepatocytes in patients without alcohol consumption or other diseases. Current studies are targeting new molecular mechanisms that underlie NAFLD and associated metabolic disorders. Many therapeutic targets ...

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors involved in the transcriptional regulation of key metabolic pathways such as lipid metabolism, adipogenesis, and insulin sensitivity. More recent work implicates all 3 PPAR isotypes (alpha, gamma, and delta, also known as beta or beta/delta) in inflammatory and atherosclerotic pathways. Because these ...

Increasing attention has been focused on the role of peroxisome proliferator-activated receptors (PPARs) in the past decade. Compelling data have begun to unite work from various arenas, such as epidemiology and vascular biology. Clinical trials with synthetic PPAR agonists have exhibited therapeutic benefits in treating various chronic diseases like atherosclerosis, diabetes mellitus and cardi...

In several species, a family of nuclear receptors, the peroxisome proliferator-activated receptors (PPARs) composed of three isotypes, is expressed in somatic cells and germ cells of the ovary as well as the testis. Invalidation of these receptors in mice or stimulation of these receptors in vivo or in vitro showed that each receptor has physiological roles in the gamete maturation or the embry...

the peroxisome proliferator-activated receptors (ppars) -α, -δ/β and -γ are the ligand-activated transcription factors involved in the regulation of fatty acid and lipoprotein metabolism, energy balance, cell proliferation and differentiation and atherosclerosis, etc. we investigated the associations of 10 single-nucleotide polymorphisms (snps) in ppars with apolipoprotein (apo) a-i/apob ratio ...

Increasing evidence suggests that common environmental contaminants can act as endocrine disrupters in fish. However, current data are biased towards environmental estrogens, highlighting the need to elucidate potential pollutant impact on other endocrine axes. Here, we report a high-throughput assay to identify chemicals interacting with piscine peroxisome proliferator-activated receptors (PPA...
