Roe Protein Hydrolysates of Giant Grouper (Epinephelus lanceolatus) Inhibit Cell Proliferation of Oral Cancer Cells Involving Apoptosis and Oxidative Stress

Figure 4

Annexin V/PI-based apoptosis of URH-treated oral cancer Ca9-22 cells. Ca9-22 cells were treated with 0, 0.5, 1, 1.5, 2, and 2.5 mg/mL of URH for 24 h. (a) Representative results of flow cytometry-based annexin V/PI double staining of URH-treated Ca9-22 cells. Annexin V (+)/PI (+) and annexin V (+)/PI (−) were calculated as the apoptosis (+) in each panel. (b) Quantification analysis of apoptosis for URH-treated Ca9-22 cells in Figure 4(a). Data, mean ± SD (). against control.
