The adipocyte hormone adiponectin is negatively correlated with obesity and insulin resistance and may exert an important antidiabetes function. In this study, primary human skeletal muscle cells were cocultured with human fat cells or incubated with adipocyte-conditioned medium in the presence or absence of the globular domain of adiponectin (gAcrp30) to(More)
AIM To examine the relationship between adiponectin and metabolic variables in the offspring of patients with type 2 diabetes mellitus. METHODS Fasting blood samples and anthropometric indices were taken from 34 subjects, offspring of patients with type 2 diabetes, and 24 healthy control subjects without any immediate family history of diabetes. Plasma(More)
Small GTPases of the Rab family regulate vesicular traffic and distribution of proteins in different cell types. Rab11a is a member of this GTP hydrolyzing protein class and acts as a mediator of insulin stimulated translocation of the glucose transporter GLUT4 in peripheral tissues including heart and skeletal muscle. Here we report on Rab11a Q70R, a(More)
We have recently shown the co-localization of Rab11 and the glucose transporter GLUT4 in cardiac muscle and an insulin-stimulated increase of Rab11 in GLUT4-containing vesicles in this tissue. We now assessed the effect of Rab11 wt and a dominant-negative mutant (N124I) on GLUT4 trafficking in the cardiomyoblast cell line H9c2 stably overexpressing the(More)
A series of substituted 4-phenyl-1,4-dihydropyridines 2a-m was tested for their inhibitory effects on L-triiodothyronine (L-T3) uptake by human HepG2 hepatoma cells. The most potent compounds were the nitro-substituted derivatives 2,6-dimethyl-4-(4'-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylic acid 3-ethyl ester 5-methyl ester (2m) and the well-known(More)
The E23K variant of the Kir6.2 gene has been shown to be associated with type 2 diabetes mellitus in Caucasian subjects. Because offspring of type 2 diabetic patients have a genetically increased risk of developing diabetes, we sought to identify the E23K variant of the Kir6.2 gene in offspring of Caribbean patients with type 2 diabetes and assess the(More)
A series of substituted 3-amino-5-phenoxythiophenes was synthesized starting from malodinitrile and carbon disulfide. The resulting dicyanoketenedithiolate reacts via Thorpe-Dieckmann cyclization with halogen methanes bearing electron-withdrawing groups to give thiophene-2-thiolates, which can be transformed into(More)
Low adiponectin levels are associated with elevated plasma alanine aminotransferase, a marker of reduced hepatic insulin sensitivity and a risk factor for type 2 diabetes. This study aims to determine the relationship between serum adiponectin level and alanine aminotransferase in diabetic and non-diabetic subjects. Fifty-six type 2 diabetic patients and 33(More)
