SUMO4 Met55Val polymorphism is associated with coronary heart disease in Japanese type 2 diabetes individuals.

The Met55Val polymorphism in the small ubiquitin-like modifier 4 (SUMO4) gene has been associated with susceptibility not only to type 1 diabetes, but also to type 2 diabetes and diabetic nephropathy. We tried to confirm the association with susceptibility to type 2 diabetes and to investigate its role in diabetic vascular complications. The polymorphism was genotyped in two independent Japanese samples (Wakayama and Tokyo) by the TaqMan method.

Polymorphisms in the IDE-KIF11-HHEX gene locus are reproducibly associated with type 2 diabetes in a Japanese population.

Context: A genome-wide association study in the French population has detected that novel single-nucleotide polymorphisms (SNPs) in the IDE-KIF11-HHEX gene locus and the SLC30A8 gene locus are associated with susceptibility to type 2 diabetes.

Objective: We investigated whether SNPs in these loci were associated with type 2 diabetes in Japanese.

Design: Two SNPs, rs7923837 and rs1111875, in the IDE-KIF11-HHEX gene locus and one SNP, rs13266634, in the SLC30A8 gene locus were genotyped in Japanese type 2 diabetic patients (n = 405) and in nondiabetic control subjects (n = 340) using the TaqMan genotyping assay system.

Bezafibrate improves bacterial lipopolysaccharide-induced dyslipidemia and anorexia in rats.

Bacterial endotoxin/lipopolysaccharide (LPS)-induced cachexia is characterized by weight loss, anorexia, and a disturbance in lipid metabolism, namely, hypertriacylglycerolemia. The aim of this study in rats with acute endotoxicity induced by an injection of LPS was to investigate whether bezafibrate, a ligand for peroxisome proliferator-activated receptor alpha and a lipoprotein lipase (LPL) activator, improved cachectic conditions, including impaired lipid metabolism. Short-term administration of LPS in the rats resulted in impairment of triacylglycerol clearance in plasma after the intake of fresh cream.
