WebInduction of the transcription factor CHOP (CCAAT-binding homologous protein; GADD 153) is a critical cellular response for the transcriptional control of endoplasmic reticulum (ER) stress-induced apoptosis. Upon nuclear translocation, CHOP upregulates the transcription of proapoptotic factors and downregulates antiapoptotic genes. WebTo confirm that CHOP mediates cell apoptosis in H1975, we silenced CHOP through siRNA and then exposed the cells to WZ35. Our results clearly show that WZ35-induced cell death in H1975 is significantly dampened upon producing CHOP deficit. We further showed that WZ35-induced ER stress is abolished when ROS is neutralized by NAC. scoot toy
