Popis: Abstract Investigations into the mechanisms by which diabetes accelerates atherosclerosis have been hampered by the lack of suitable animal models. We hypothesized that streptozotocin-treated LDL receptor-deficient mice would be a good model of diabetic atherosclerosis because streptozotocin causes diabetes in the parent C57BL/6 strain and because in these mice diet-induced hypercholesterolemia leads to the formation of advanced atherosclerotic lesions throughout the aorta. Diabetes was induced in 18 mice by intraperitoneal injection of streptozotocin. Low-dose insulin was given subcutaneously to prevent excessive mortality and extreme elevations in triglyceride levels. The control group was subjected to sham injections. Both groups were fed a diet containing .075% cholesterol for six months. Average blood glucose was higher in the diabetic group than in the control group (257±67 mg/dL versus 111±7 mg/dL, P −/− mice.
