The peroxisome proliferator-activated receptors (PPAR) alpha, beta/delta, and gamma are ligand-activated nuclear receptors involved in a number of physiological processes, including lipid and glucose homeostasis, inflammation, cell growth, differentiation, and death. PPAR agonists are used in the treatment of human diseases, like type 2 diabetes and dyslipidemia, and PPARs appear as promising t...

Peroxisome proliferator-activated receptors (PPARs) are ligand-dependent transcription factors of the nuclear hormone receptor super-family, which includes the steroid, retinoid, and thyroid hormone receptors. The PPARs can be activated by fatty acids and their eicosanoid metabolites, and have until recently been considered primarily to regulate genes involved in glucose and lipid homeostasis. ...

Peroxisome proliferator-activated receptors (PPARs), which are known to regulate lipid homeostasis, are tightly controlled by nutrient availability, and they control nutrient handling. In this paper, we focus on how nutrients control the expression and action of PPARs and how cellular signaling events regulate the action of PPARs in metabolically active tissues (e.g., liver, skeletal muscle, he...

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated nuclear receptors regulating the expression of genes that control lipid and glucose homeostasis, modulating thus the major metabolic disorders predisposing to atherosclerosis and subsequent cardiovascular diseases [1]. Moreover, PPARs exert additional anti-inflammatory and lipid-modulating effects in the arterial wall, bei...

Peroxisome proliferator-activated receptors (PPARs) and (liver X receptors) LXRs are ligand-activated transcription factors that control lipid and glucose metabolism, as well as the inflammatory response. Because the macrophage plays an important role in host defense and immunoinflammatory pathologies, particular attention has been paid to the role of PPARs and LXRs in the control of macrophage...

Lipid mediators can trigger physiological responses by activating nuclear hormone receptors, such as the peroxisome proliferator-activated receptors (PPARs). PPARs, in turn, control the expression of networks of genes encoding proteins involved in all aspects of lipid metabolism. In addition, PPARs are tumor growth modifiers, via the regulation of cancer cell apoptosis, proliferation, and diffe...

Nowadays, the study of the peroxisome proliferators activated receptors (PPARs) as potential targets for cancer prevention and therapy has gained a strong interest. From a biological point of view, the overall responsibility of PPARs in cancer development and progression is still controversial since several studies report both antiproliferative and tumor-promoting actions for these signaling mo...

The nuclear receptor superfamily consists of 48 mammalian transcription factors that regulate nearly all aspects of development, inflammation, and metabolism. Two subclasses, the Peroxisome Proliferator-Activated Receptors (PPARs) and Liver X Receptors (LXRs), are lipid-sensing receptors that have critical roles in lipid and glucose metabolism. The parallel epidemics of obesity and diabetes shi...

receptors called peroxisome proliferator-activated receptors (PPARs) have opened up the possibilities for treatment of many metabolic diseases including type 2 diabetes. PPARs have three subtypes, i.e. PPARa , PPARd , and PPARg . PPARs modulate expression of genes involved in the transport and metabolism of glucose and lipids. PPARa is mainly expressed in tissues such as liver, which is activat...

Peroxisome proliferator-activated receptors (PPARs) are members of the nuclear hormone receptor superfamily and are expressed in a variety of tissues including skin and cells of the immune system. They act as ligand-dependent transcription factors which heterodimerize with retinoid X receptors to allow binding to and activation of PPAR responsive genes. Through this mechanism, PPAR ligands can ...
