Sulfatides are one of the major sphingoglycolipids in mammalian serum and are synthesized and secreted mainly from the liver as a component of lipoproteins. Recent studies revealed a protective role for serum sulfatides against arteriosclerosis and hypercoagulation. Although peroxisome proliferator-activated receptor (PPAR) α has important functions in hepatic lipoprotein metabolism, its associ...

Renal cell carcinoma (RCC) is the sixth most common cancer in the US. While RCC is highly metastatic, there are few therapeutics options available for patients with metastatic RCC, and progression-free survival of patients even with the newest targeted therapeutics is only up to two years. Thus, novel therapeutic targets for this disease are desperately needed. Based on our previous metabolomic...

We have modelled elaidyl-sulfamide (ES), a sulfamoyl analogue of oleoylethanolamide (OEA). ES is a lipid mediator of satiety that works through the peroxisome proliferator-activated receptor alpha (PPARα). We have characterised the pharmacological profile of ES (0.3-3 mg/kg body weight) by means of in silico molecular docking to the PPARα receptor, in vitro transcription through PPARα, and in v...

Albumin-bound fatty acids is the main cause of renal damage, PPARα is responsible in the metabolism of fatty acids. Previous study found that PPARα played a protective role in fatty acids overload associated tubular injury. The aim of the present study is to investigate whether fenofibrate, a PPARα ligands, could contribute to the renoprotective action in fatty acids overload proximal tubule ep...

BACKGROUND AND AIMS Clofibrate, an established PPARα ligand, has recently been shown to have anticancer activity yet its mechanisms of action remain to be characterized. This study examined the effect of clofibrate on heme oxygenase-1 (HO-1) gene expression in A2780 (human ovarian cancer) and DU145 (human prostate cancer) cells. METHODS AND RESULTS We demonstrate that clofibrate induces HO-1 ...

Inhibitor of nuclear factor kappa-B kinase beta (IKKβ) plays a critical role in cell proliferation and inflammation in various cells by activating NF-κB signaling. However, the interrelationship between peroxisome proliferator-activated receptor α (PPARα) and IKKβ in cell proliferation is not clear. In this study, we investigated the possible role of PPARα in the hepatic cell death in the absen...

Background. Soccer, combat sports and motorcycling have all been classified as mixed in terms of their metabolism predominance thus showing a common multifaceted nature of physical requirements, which include aerobic capacity, strength, endurance, power and agility. Objectives. The aim of the current study was to compare allelic and genotype frequencies of four well-known polymorphisms among a...

We investigated whether palmitoleic acid, a fatty acid that enhances whole body glucose disposal and suppresses hepatic steatosis, modulates triacylglycerol (TAG) metabolism in adipocytes. For this, both differentiated 3T3-L1 cells treated with either palmitoleic acid (16:1n7, 200 μM) or palmitic acid (16:0, 200 μM) for 24 h and primary adipocytes from wild-type or PPARα-deficient mice treated ...

Fatty acids comprise the primary energy source for the heart and are mainly taken up via hydrolysis of circulating triglyceride-rich lipoproteins. While most of the fatty acids entering the cardiomyocyte are oxidized, a small portion is involved in altering gene transcription to modulate cardiometabolic functions. So far, no in vivo model has been developed enabling study of the transcriptional...

PPARs are ligand-activated nuclear transcription factors that regulate β-oxidation of fatty acids in the cardiovascular system and PPARα isoform is a putative target for regulation of cardiovascular function. High salt diet is an injurious stimulus to cardiovascular function but its effect on PPARα and PPARα–associated profile of proteins is unknown. Quantitative proteomics involving a twodimen...
