Figure 2.
Anti-proliferative effects of OPD in SK-Hep-1 human hepatoma cells (left) and MRC5 human normal cell line (right). SK-Hep-1 cells were cultured in a 96-well plate and treated with the indicated concentrations of OPD for 24–72 h. MRC5 cells were cultured in a 96-well plate and treated with the indicated concentrations of OPD for 72 h. The cell proliferative activity was determined using the SRB assay. The % cell proliferation value was calculated by the mean absorbance of samples/absorbance of the vehicle-treated control as described in the Materials and Methods. Data are presented as the means ± S.E. (n = 3).
