Gallic acid induced apoptotic events in HCT-15 colon cancer cells

Figure 2 Cell proliferation inhibition by gallic acid of colon cancer cells. Human colorectal carcinoma HCT-15 cells grown in 96-well plate were treated with various concentration of gallic acid (GA) (0-1500 μmol/L) for 72 h. Percentage of mean cell viability along-with the SD is indicated (n = 3). Mean differences are significant compared with untreated control cells (P < 0.05 vs untreated control cells). Statistical analysis showed that GA treatment results in significant inhibition (^aP < 0.05) compared with untreated control cells starting at 200 μmol/L for HCT-15 cells. Data represents mean ± SD.
