Figure 1From: Regulation of cell cycle transition and induction of apoptosis in HL-60 leukemia cells by lipoic acid: role in cancer prevention and therapyControl of cell growth and viability in HL-60 cells by LA. (A) Cells were treated with 0, 1, 2.5 and 5 mM LA and the cell numbers were determined at 24, 48, 72 and 96 h. (B) Cell viability was measured using the trypan blue dye exclusion assay. Effects of LA were presented as a percentage of control, and values are expressed as mean ± SD for three experiments.Back to article page
