摘要: To dissect the effect of hyperinsulinemia versus hyperglycemia on TNF-related apoptosis inducing ligand (TRAIL) expression in macrovascular district, we measured TRAIL mRNA and protein four groups animals: streptozotocin (SZT)-induced diabetic rats, vehicle-treated control animals, rats treated with insulin non-diabetic insulin. While aortas did not show significant differences respect to both vivo for 16 days showed a decrease either rats. Moreover, vitro treatment rat human vascular smooth muscle cells (VSMC) induced down-regulation protein. addition recombinant VSMC promoted dose-dependent release bioactive nitric oxide (NO), this was significantly counteracted by pre-exposure These findings suggest that might act as an endogenous regulator tone chronic elevation contribute abnormalities characterizing type-2 diabetes mellitus down-regulating activity.
