Synergistic Apoptosis-Inducing Antileukemic Effects of Arsenic Trioxide and Mucuna macrocarpa Stem Extract in Human Leukemic Cells via a Reactive Oxygen Species-Dependent Mechanism

Figure 6

Expressions of apoptosis-related proteins in leukemia cells treated with arsenic trioxide (ATO), crude methanolic extract of Mucuna macrocarpa (CMEMM), and/or N-acetyl cysteine (NAC). Whole cell lysates were prepared from HL-60 or Jurkat cells treated with 2.5 μM ATO, 50 μg/mL CMEMM, 5 mM NAC, or indicated combinations for 24 h. Proteins as indicated were analyzed by Western blotting with β-actin as loading control. Representative blots shown were from one of three independent experiments.
