BCL2 and neoplasm: Antiapoptotic protein Bcl‐2, proapoptotic protein Bax, and downstream cleaved caspase‐3 are involved in apoptosis cascade reaction and apoptosis of tumor cells38 Both in vitro and in vivo experiments in this study manifested that the increased miR‐205‐3p expression led to the significant decrease in the cleaved caspase‐3 expression, significant increase in the Bcl‐2/Bax ratio in cells, thus reducing the apoptosis level.
