In ovarian cancer cell lines, an evaluation of Annexin V-stained cells using flow cytometry showed that B7-H3 silencing promoted apoptosis mainly in the early stage, and subsequent western blotting results showed a decrease in the expression of the anti-apoptotic proteins Bcl-2 and Bcl-xl, as well as an increase in the levels of the proapoptotic proteins Bax, caspase-8 and cleaved caspase-8 [71]. The gene discussed is CD276; the disease is ovarian carcinoma.
