Increased Apaf-1 expression in leukemic cells after

Apaf-1 gene transfection. (A) Western blot detection of Apaf-1 expression in the wild-type (WT) and transfected leukemic cells (Apaf-1). Leukemic cells were transfected with Apaf-1/pCMV2 plasmid DNA. (B) Relative intensity of Apaf-1 expression. The immunoblot shown in (A) was analyzed with a densitometer, and the intensities of Apaf-1 bands were indicated as percentage of integrated density.
