Hormones, Growth Factors, Cell Signaling, Cell Biology and Structure Stimulation of Proximal Tubule Cell Apoptosis by Albumin Bound Fatty Acids Mediated by Peroxisome Proliferator Activated Receptor Tubulotoxic Effects of Proteinuria: The Lipid Connection Is Strengthened. There is currently little doubt that sustained high-grade proteinuria has damaging renal effects. While the mechanisms invol...

There are three peroxisome proliferator-activated receptors (PPARs) subtypes which are commonly designated PPAR alpha, PPAR gamma and PPAR beta/delta. PPAR alpha activation increases high density lipoprotein (HDL) cholesterol synthesis, stimulates "reverse" cholesterol transport and reduces triglycerides. PPAR gamma activation results in insulin sensitization and antidiabetic action. Until rece...

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...

conclusions in conclusion, the ace and pparg genes do not have a key role in conferring risk for diabetic nephropathy. results ace id genotypes followed hardy-weinberg equilibrium in both cases and controls. but p12a genotypes deviated from hardy-weinberg equilibrium in diabetic controls. chi2 test was applied for the analysis of genotypic distributions in genotypic and dominant models. odds ra...

Systemic sclerosis (SSc) is a heterogenous immune-mediated fibrotic disease. Disability of daily life in SSc patients largely depending on skin fibrosis starting distal site limb. However, there limited randomized control trial (RCT)-proven therapies for SSc. The effect anti-fibrotic drug, including transforming growth factor (TGF)-beta ab, peroxisome proliferator-activated receptor-gamma (PPAR...

Circadian clock mechanisms are far-from-equilibrium dissipative structures. Peroxisome proliferator-activated receptors (PPAR alpha, beta/delta, and gamma) play a key role in metabolic regulatory processes, particularly in heart muscle. Links between circadian rhythms (CRs) and PPARs have been established. Mammalian CRs involve at least two critical transcription factors, CLOCK and BMAL1 (Gekak...

Parathyroid hormone-related protein (PTHrP) has been implicated in many processes during normal and pathological pregnancies. In the human fetal membranes, PTHrP exhibits cytokine-like actions. We have recently shown that inhibitors of the nuclear factor-kappa B (NF-kappaB) and activators of the peroxisome proliferator-activated receptor (PPAR)-gamma signalling pathways down-regulate cytokine r...

background : peroxisome proliferator-activated receptor gamma (ppar γ) is a transcription factor, which is abundantly expressed in adipose tissue and has a direct link to adiposity. it seems that long-chain polyunsaturated fatty acids (lc-pufas) can regulate ppar γ expression. the purpose of this study was to investigate the effects of n-3lc pufa supplementation on plasma levels of ppar γ and t...

Peroxisome proliferator-activated receptors (PPARs) are transcription factors belonging to the superfamily of nuclear receptors. Three isoforms (alpha, delta, and gamma) have been described. They act on DNA response elements as heterodimers with the nuclear retinoic acid receptor. Their natural activating ligands are fatty acids and lipid-derived substrates. PPAR-alpha is present in liver, hear...

Selective cyclooxygenase-2 (COX-2) inhibitors have been demonstrated to inhibit the proliferation of a variety of cancer cells including hepatocellular carcinoma (HCC). We sought to explore the mechanisms by which JTE-522, a selective COX-2 inhibitor, suppressed the growth of human HCC cells. HCC cells (HepG2, HLF, huH1, Huh7, and PLC/PRF/5 cells) did not express COX-2 at either the mRNA or pro...
