Effect of IFN-γ on expression of Bcl-x and Bax.

Expression of Bcl-x and Bax was evaluated by Western blot analysis. (A) Cells were incubated with or without rhEPO (10 U/mL) or rhIFN-γ (1000 U/mL), or both, for the indicated time, and the same amount of whole cell lysates was loaded. The upper panel shows the expression of Bcl-x, and the lower panel shows the expression of Bax. (B) Lysates from cells incubated for 16 hours with or without rhEPO or IFN-γ, or both, were loaded.
