钙离子超载在镉致大鼠肝细胞凋亡中的作用
Cadmium Induced Apoptosis in Rat Hepatocytes by Calcium Overloading
摘要
Abstract
The aims of this study were to explore the effect of [Ca2+]I on the apoptosis of rat hep-atocytes induced by cadmium. Rat hepatocytes were isolated by a two-step perfusion technique. After 24 h planting, hepatocytes were treated with cadmium in the presence or absence of Bapta-AM. Cell viability was evaluated with a colorimetric using MTT level. Cell morphology and apoptosis were photographed under inverted and fluorescence microscope. [Ca2+ ]I, ROS generation and △ψm collapse were evaluated with flow cytometry. The results showed sharp deformation, necrosis and apoptosis in hepatocytes with the dose of Cd increased and time prolonged. Cd induced [Ca2+]I increased, △ψm collapse and ROS generation (P<0. 01). Bapta-AM effectively inhibited Cd-induced cytotoxicity (P<0. 05 or P<0. 01). It was showed that cadmium induced apoptosis in rat hepatocytes by calcium overloading.关键词
