B-cell expression of Bcl-2 family members. (A and B) B cells were isolated from littermate WT and B-Traf3^−/− mice. Whole cell lysates of WT and TRAF3^−/− B cells were analyzed with Western blotting for Bcl-2 (A) and Bcl-xL (B) expression. Representative blots of three independent experiments are shown. (C) WT and TRAF3^−/− B cells were treated with either DMSO or 5 μM KG-501 for 24 h. Mcl-1 expression in intact cells was assayed with flow cytometry. Representative data from three independent experiments are shown.
