Recent studies have found that cyclooxygenase-2 (COX-2) protein expression was low and inducible with cytokines in prostate cancer cells (in the absence of serum) and that, in contrast, COX-2 expression was high in normal prostate epithelial cells (EC). Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) was expressed at high levels in the prostate cancer cell line PC-3 but not in ECs...

Fatty acid translocase (FAT)/CD36 is a glycoprotein involved in multiple membrane functions including uptake of long-chain fatty acids and oxidized low density lipoprotein. In mice, expression of the gene is regulated by peroxisome proliferator-activated receptor (PPAR) in the liver and by PPAR in the adipose tissues (Motojima, K., Passilly, P. P., Peters, J. M., Gonzalez, F. J., and Latruffe, ...

Pulmonary fibrosis is characterized by alterations in fibroblast phenotypes resulting in excessive extracellular matrix accumulation and anatomic remodeling. Current therapies for this condition are largely ineffective. Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is a member of the nuclear hormone receptor superfamily, the activation of which produces a number of biological ef...

BACKGROUND Diverse environmental contaminants, including the plasticizer di(2-ethylhexyl)phthalate (DEHP), are hepatocarcinogenic peroxisome proliferators in rodents. Peroxisome proliferator-activated receptor-alpha (PPAR-alpha) activation and its sequelae have been proposed to constitute a mode of action (MOA) for hepatocarcinogenesis by such agents as a sole causative factor. Further, based o...

Objective—We recently reported that the peroxisome proliferator-activated receptor (PPAR ) ligands 15-deoxyprostaglandin J2 (15d-PGJ2) and ciglitazone increased cultured endothelial cell nitric oxide (NO) release without increasing the expression of endothelial nitric oxide synthase (eNOS). The current study was designed to characterize further the molecular mechanisms underlying PPAR -ligand–s...

Most cis-acting regulatory elements have generally been assumed to activate a single nearby gene. However, many genes are clustered together, raising the possibility that they are regulated through a common element. We show here that a single peroxisome proliferator response element (PPRE), located between the mouse PEX11 alpha and perilipin genes, confers on both genes activation by peroxisome...

The transport and metabolism of organic cationic endobiotics, nutrients, and drugs are essential hepatic functions. Slc22A1 is the basolateral liver transporter mediating the uptake of organic cations; however, little is known about the regulation of this transport protein. Peroxisome proliferator agonist receptor (PPAR)-alpha and -gamma agonists are commonly used agents that regulate many hepa...

Purpose: The peroxisome proliferator-activated receptor(PPAR ), a ligand-dependent transcription factor belonging to the family of nuclear receptors, has been implicated in the control of cyclooxygenase (COX) 2 expression in some tissue, although the exact mechanism(s) of this activity has not been elucidated. In this study we explored the possible mechanism(s) of control of COX-2 gene expressi...

High cross-polarization isolation (CPI) is crucial to the accurate polarization measurement using polarimetric phased array radar (PPAR). In this article, we propose an adaptive direction-dependent state configuration ( AD 2 PSC) method improve isolation. Compared with conventional fixed of radi...

Peroxisome proliferator-activated receptors (PPARs) are involved in the regulation of lipid and glucose metabolism. PPAR agonists improve insulin sensitivity and hyperglycemia and are effective in treating type 2 diabetes mellitus (T2DM), whereas PPAR agonists are used to treat dyslipidemia and atherosclerosis. The goal here was to examine the efficacy of a selective PPAR agonist {(S)-3-[3-(1-c...
