Events associated with apoptotic effect of p-Coumaric acid in HCT-15 colon cancer cells

Figure 2 p-Coumaric acid induced reactive oxygen species generation. Human colorectal carcinoma (HCT-15) cells were cultured in the presence or absence of p-Coumaric acid for the specified time points. Dichlorofluorescein-diacetate fluorescence intensity was detected by using flow cytometry. Data is representative of three independent experiments and the mean differences are significant at 12, 24 and 48 h.
