ANXA5 and diffuse large B-cell lymphoma: To further verify the cytotoxicity effect of ABT‐199 and Apatinib when used in combination, we treated DLBCL cells with ABT‐199 at various concentrations (1, 2, 4 nm) in the presence or absence of different concentrations of Apatinib (10, 20, 40 μm) for 12 and 24 h and then the percentage of apoptotic cells was detected by Annexin V/DAPI dual staining.
