Question: Question: Does maslinic acid activate mitochondria-dependent apoptotic pathway in cardiac carcinoma?
Answer: Our data demonstrated that natural compound, MA, suppressed the growth of cardiac carcinoma by inducing apoptosis via the p38 MAPK/mitochondria/caspase pathway. MA and its derivatives may be promising anti-tumor agents for cardiac carcinoma treatment in the future. (Supplemental Figures available here.).
