Genistein aglycone, a soy derived isoflavone, has been demonstrated to be effective in reducing cardiovascular risk in postmenopausal women. We therefore investigated its effects in an experimental model of postmenopausal metabolic syndrome. Female spontaneously hypertensive obese rats (SHROB, n=40), a genetic model of syndrome X, and age-matched Wistar Kyoto (WKY, n=40) rats were used. A group...

To date, polymorphisms in several genes have been associated with a strength/power performance including alpha 3 actinin, ciliary neurotrophic factor, vitamin D receptor, or angiotensin I converting enzyme, underlining the importance of genetic component of the multifactorial strength/power-related phenotypes. The single nucleotide variation in peroxisome proliferator-activated receptor alpha g...

OBJECTIVE Fenofibrate, a peroxisome proliferator-activated receptor-α (PPARα) agonist, reduces triglyceride (TG) concentrations by 25-60%. Given significant interindividual variations in the TG response, we investigated the association of PPARA rare variants with treatment response in the Genetics of Lipid-Lowering Drugs and Diet Network study. METHODS We calculated the change in the TG conce...

compounds, such as fibrates (hypolipidemic drugs), phthalate ester plasticizers, fatty acid analogues, cause induction of several proteins related to lipid metabolism, including peroxisomal b-oxidation (Px-ox), accompanied by a hypolipidemic effect in rodents. Since the peroxisome proliferatoractivated receptors (PPARs), which are nuclear transcriptional receptors, were found, they have been re...

In rodents, fibroblast growth factor 21 (FGF21) has emerged as a key metabolic regulator produced by liver. To gather preliminary data on the potential importance of FGF1, co-regulated genes, and upstream metabolic genes, we examined the hepatic mRNA expression in response to nutrition and inflammation in dairy cows. In experiment 1, induction of ketosis through feed restriction on d 5 postpart...

Intestinal metaplasia of the oesophagus (Barrett’s oesophagus) is the most important risk factor for oesophageal adenocarcinoma. Although the role of mixed bile and acid gastro-oesophageal reflux is well established, the contribution of nuclear receptor signalling in the pathogenesis of Barrett’s oesophagus remains largely unknown. The recent article by Chang et al. (Gut 2007;56:906–17) showing...

The WNT/b-catenin signaling pathway has been identified as an important endogenous regulator of hepatic cytochromeP450 (P450) expression inmouse liver. In particular, it is involved in the regulation of P450 expression in response to exposure to xenobiotic agonists of the nuclear receptors constitutive androstane receptor (CAR), aryl hydrocarbon receptor (AhR), and Nrf2. To systematically eluci...

Prostate cancer (PC) is a common neoplasm, and metastatic PC remains incurable. The study aims to screen key microRNAs (miRNAs) and transcription factors (TFs) involved in PC.The miRNA expression profile dataset (GSE45604) was downloaded from Gene Expression Omnibus database, including 50 PC and 10 normal specimens. Differentially expressed miRNAs (DEmiRNAs) were identified through limma packag...

AIMS/INTRODUCTION Peroxisome proliferator-activated receptor-α (PPARα) is a therapeutic target for hyperlipidemia. K-877 is a new selective PPARα modulator (SPPARMα) that activates PPARα transcriptional activity. The aim of the present study was to assess the effects of K-877 on lipid metabolism in vitro and in vivo compared with those of classical PPARα agonists. MATERIALS AND METHODS To com...
