Mcl-1 levels influenced cytarabine-induced apoptosis in AML cells. A, C, The cell inhibition and apoptosis percentages of HL-60 or THP-1 cells treated with increasing concentrations of Ara-C for 24 h were examined by trypan blue and AO-EB staining. B, D, Western blot analysis of PARP, p-p38, Mcl-1 and p-H2AX protein expression in HL-60 or THP-1 cells treated with Ara-C for 24 h
