摘要：

In this study, we delineated the apoptotic signaling pathways activated by sodium selenite in NB4 cells. NB4 cells were treated with 20 mu M sodium selenite for different times. The activation of caspases and ER stress markers, ROS levels, mitochondrial membrane potential and cell apoptosis induced by sodium selenite were analyzed by immunoblotting analysis, DCF fluorescence and flow cytometric respectively. siRNA was used to detect the effect of GADD153 on selenite-induced cell apoptosis. Sodium selenite-induced reactive oxygen species generation is an early event that triggers endoplasmic reticulum stress mitochondrial apoptotic pathways in NB4 cells.
