| Objective: To investigate the effects of cardamonin on regulation of glucose metabolism on the vascular smooth muscle
cells (VSMCs) and its possible mechanism in the insulin-resistant condition. Methods: VSMCs were cultured in high glucose ( 2.5×
l0-2 mol·L-1) and high insulin (100 U·L-1) medium for 72 hours, then cardamonin was added to incubate for 48 hours. Glucose consumption,
hexokinase activity and proliferation of VSMCs were measured in the experiment. Results: Cultured with high glucose and high insulin
for 72 hours, glucose consumption of VSMCs was significantly decreased (P<0.01). Cardamonin significantly increased the glucose
consumption and hexokinase activity of VSMCs in IR statue (P<0.01) and inhibited the proliferation induced by high glucose and high
insulin (P<0.01). Conclusion: The results suggested that cardamonin could improve the glucose metabolism and inhibit the proliferation
of VSMCs in the IR condition, which might be related to enhancement of hexokinase activity. |
