when grown in monolayer culture at low density and with the addition of serum, cartilage cells dedifferentiate or are overgrown by fibroblast-like cells. the aim of this study was to optimize the cultivation of chondrocytes in monolayer culture and to slow down their transformation or their overgrowth by fibroblast-like cells. the interaction between chondrocytes and cartilage-specifc matrix is...

PURPOSE It was determined in cultured human retinal pigment epithelial (HRPE) cells whether there is gene expression for insulin, insulin-like growth factors (IGFs), insulin and IGF receptors, and IGF-binding proteins (IGFBPs); if these peptides are secreted by the HRPE cells, and whether they have mitogenic effects on these cells; and if IGF-related peptides bind to HRPE cells. METHODS Rever...

vitamin d deficiency is prevalent in diabetes type 2 and this vitamin may be related to insulin action. this randomized controlled trial study was done to evaluate the effect of vitamin d supplementation on glucose control and insulin resistance in patients with diabetes type 2.participants of this randomized clinical trial study consisted of 28 patients with type 2 diabetes who received 100 mi...

objective: arctium lappa (burdock), (a. lappa) root has hypoglycemic and antioxidative effects, and has been used for treatment of diabetes in tradition medicine. this study was conducted to evaluate the antidiabetic and hypolipidemic properties of a. lappa root extract on nicotinamide-streptozotocin (na-stz)-induced type2 diabetes in mice.materials and methods: in this investigation, 70 adult ...

objective: type 2 diabetes is associated with elevated oxidative stress and decline in antioxidant defense. vitamin e supplementation reduces oxidative stress level in diabetic pa-tients. purpose of this study was to evaluate the effect of vitamin e supplementation on glycemic control and lipid profile in type 2 diabetic patients. material and methods: in this study 31 type 2 diabetic patients ...

Using affinity cross-linking techniques, we report the presence of type I IGF and type II IGF receptors in Madin-Darby canine kidney cells, a line of cells lacking insulin receptors. The IGF receptors were further characterized by competition binding studies and found to be similar to IGF receptors in other tissue types. In Madin-Darby canine kidney cells, the type I IGF receptor binds IGF-I gr...

UNLABELLED The effects of insulin-like growth factor I (IGF-I) and insulin on free fatty acid (FFA) and glucose metabolism were compared in eight control and eight type 2 diabetic subjects, who received a two-step euglycemic hyperinsulinemic (0.25 and 0.5 mU x kg(-1) x min(-1)) clamp and a two-step euglycemic IGF-I (26 and 52 pmol x kg(-1) x min(-1)) clamp with [3-(3)H]glucose, [1-(14)C]palmita...

The insulin-like growth factors IGF-I and IGF-II are potent mitogens for several breast tumor cell lines in culture. Additionally, both IGF-I and IGF-II mRNAs are easily detected in the majority of breast tumor specimens examined, while no breast cancer epithelial cell lines we have studied express authentic IGF-I mRNA, and few lines express IGF-II mRNA. Although receptors for insulin, IGF-I, a...
