Fig. 3: USP15 overexpression inhibits MM cell apoptosis.

a, b After RPMI 8226 and U266 cells were transfected with siNC plus empty pLVX-Puro (vector), siUSP15#1, siUSP15#2, or pLVX-Puro-USP15 for 48 h, apoptosis in the RPMI 8226 and U266 cells was measured by flow cytometry with Annexin V-FITC/PI staining. ***P < 0.001 compared with vector + siNC
