a Western Blot of whole cell lysate after transfection with Bcl-2 siRNA and with antibodies against Bcl-2, and the housekeeping protein β-actin. b Apoptosis was measured in Kelly cells after transfection with Bcl-2 siRNA. The enrichment factor was used as a parameter of apoptosis. c Proliferation was measured in Kelly cells after transfection with Bcl-2 siRNA. The proliferation rate is given as a percentage of control. d Western Blot of whole cell lysate after transfection with Mcl-1 siRNA and with antibodies against Mcl-1, and the housekeeping protein β-actin. e Apoptosis was measured in Kelly cells after transfection with Mcl-1 siRNA.
