Non insulin dependent diabetes in sand rat (Psammomys obesus) and production of collagen in cultured aortic smooth muscle cells. influence of insulin.
In this report, we have shown that the standard laboratory diet administered to Psammomys obesus (sand rat) from Beni Abbes in Algeria, induced a non-insulin dependent diabetes, characterised by increase of body weight (p<0.001) as well as hyperinsulinemia, hyperglycemia and hypercholesterolemia. In cultured aortic smooth muscle cells (SMC) of sand rats, type I and type III collagen biosynthesis and insulin effects, at low dose, on these parameters were investigated. In all experimental conditions of cultured SMC study, The alpha chains of type I collagen were analysed by immunoblotting in media and cells. Metabolic radiolabelling and Immunochemical procedures revealed that, in diabetic state, synthetic SMC (SMCs) actively produce type I and III collagen which are synthesised in the cells and secreted in the medium; type I collagen was predominant as compared with type III collagen. Diabetes enhanced the collagen synthesis. Low dose of Insulin added to the medium, during 48 h of incubation, induced a marked reduction in the synthesis of collagen types, especially type I collagen.
