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

Figure 5 Lipid layer break provoked by gallic acid. HCT-15 cells were treated with gallic acid (GA) and evaluated using merocyanine-540 to quantify the lipid layer breaks (LLBs). The fluorescence intensity was estimated using flow cytometry. Data is representative of three independent experiments, mean differences are significant at 12 h and 24 h compared with untreated control cells (P < 0.05 vs untreated control cells).
