1 Cholesterol accumulation and diabetes in pancreatic beta-cell-specific SREBP-2 transgenic mice: a new model for lipotoxicity. Cholesterol sterol regulatory element binding factor 2 Mus musculus
2 Diabetes in TgRIP-SREBP-2 mice was primarily due to defects in glucose- and potassium-stimulated insulin secretion as determined by glucose tolerance test. Glucose sterol regulatory element binding factor 2 Mus musculus
3 Diabetes in TgRIP-SREBP-2 mice was primarily due to defects in glucose- and potassium-stimulated insulin secretion as determined by glucose tolerance test. Potassium sterol regulatory element binding factor 2 Mus musculus
4 Diabetes in TgRIP-SREBP-2 mice was primarily due to defects in glucose- and potassium-stimulated insulin secretion as determined by glucose tolerance test. Glucose sterol regulatory element binding factor 2 Mus musculus
5 SREBP-2-expressing islets also contained increased esterified cholesterol and unchanged triglycerides with reduced ATP levels. Cholesterol sterol regulatory element binding factor 2 Mus musculus
6 SREBP-2-expressing islets also contained increased esterified cholesterol and unchanged triglycerides with reduced ATP levels. Adenosine Triphosphate sterol regulatory element binding factor 2 Mus musculus
7 Taken together, these results indicate that activation of SREBP-2 in beta-cells caused severe diabetes by loss of beta-cell mass with accumulation of cholesterol, providing a new lipotoxic model and a potential link of disturbed cholesterol metabolism to impairment of beta-cell function. Cholesterol sterol regulatory element binding factor 2 Mus musculus
