In terms of a series of protein markers associated with tumor cells apoptosis and survival, on the one hand, the pro-apoptotic proteins including Bim, Bad, Bax, caspase 3, and caspase 9 in each group were also detected, indicating that compared with the control group, the protein expressions of HMSC-128-EV group were significantly higher (p < 0.05) (Figures 6D,E). The gene discussed is BCL2L11; the disease is neoplasm.
