Effect of different sugars on anti‐proliferative activity of AML on K562 cells. Cells were incubated with AML (20 μg/ml) and/or sugar (50 mm) (Lac for lactose, gal for galactose, glu for glucose, man for mannose, fru for fructose; ± cells incubated with or without AML). Data expressed as mean ± SD, obtained from experiments performed in triplicate, *P < 0.05 versus control.
