in this presentation, we review briefly on biogenesis of peroxisomes with regard to the recent findings on biogenesis. peroxisomes perform a range of various functions as oxidation of very long chain fatty acids, generation and removal of hydrogen peroxide, while peroxisomes have also been implicated in β-oxidation of aromatic and cyclic compounds, synthesis of plasmalogens, isoprenoids, lysine...
OBJECTIVE Peripheral arterial disease is highly prevalent in the elderly and in the subjects with cardiovascular risk factors such as diabetes. Approximately 2% to 4% of those affected with peripheral arterial disease commonly complain of intermittent claudication. Cilostazol, a type III phosphodiesterase inhibitor, is the only Food and Drug Administration-approved drug for the treatment of int...
OBJECTIVE Neuropilin-1 (NRP-1) is a multidomain membrane receptor involved in angiogenesis and development of neuronal circuits, however, the role of NRP-1 in cardiovascular pathophysiology remains elusive. APPROACH AND RESULTS In this study, we first observed that deletion of NRP-1 induced peroxisome proliferator-activated receptor γ coactivator 1α in cardiomyocytes and vascular smooth muscl...
OBJECTIVE Development of calcific aortic valve stenosis involves multiple signaling pathways, which may be modulated by peroxisome proliferator-activated receptor-γ). This study tested the hypothesis that pioglitazone (Pio), a ligand for peroxisome proliferator-activated receptor-γ, inhibits calcification of the aortic valve in hypercholesteremic mice. METHODS AND RESULTS Low density lipoprot...
Peroxisome proliferator-activated receptors (PPARs) are implicated in several metabolic disorders with altered glucose and lipid metabolism, including atherosclerosis and diabetes. In the present study, we evaluated the in vitro and ex vivo effects of high glucose concentrations on macrophage PPAR mRNA expression. Exposition of monocyte-derived macrophages isolated from healthy donors to a high...
Psoriasis is a polygenic, inflammatory and progressive disease, characterized by an abnormal differentiation and hyperproliferation of keratinocytes, associated with impaired immunologic activation and systemic disorders, while psoriatic arthritis is a chronic inflammatory articular disease. Pathophysiology of psoriasis comprises a dysfunction of the immune system cells with an interactive netw...
The structurally diverse peroxisome proliferators ciprofibrate, clofibrate, and bis(2-ethylhexyl) phthalate [(EtHx)2 greater than Pht] increase the activities of hepatic catalase and peroxisomal fatty acid beta-oxidation enzymes in conjunction with profound proliferation of peroxisomes in hepatocytes. In order to delineate the level at which these enzymes are induced in the liver, the transcrip...
The mechanism by which nongenotoxic peroxisome proliferators induce hepatocellular carcinomas in rats and mice remains intriguing. The available experimental evidence suggests that the proliferation of peroxisomes and induction of peroxisome-associated enzymes results in oxidative stress which then leads to tumorigenesis. However, so far no direct evidence for oxidative DNA damage in livers of ...
Several contaminants detected in aquatic ecosystems are agonists of peroxisome proliferator-activated receptors (PPARs). Peroxisome proliferator-activated receptors interact with the retinoid X receptor (RXR) to activate the transcription of genes that control a variety of physiological functions. We cloned and sequenced partial cDNA fragments of rainbow trout (Oncorhynchus mykiss) PPARalpha an...
