BCL2 and cancer: The intrinsic apoptotic pathway is mainly regulated by BCL‐2 family proteins and caspase family proteins that play an important role in LPS‐induced lung endothelial cell apoptosis.5 A previous study demonstrated that genistein inversely affects cancer cells apoptosis via regulation of BCL‐2.22 However, whether GSS regulated BCL‐2 expression in ECs after stimulation with LPS was unknown.
