Curcumin-Induced Apoptosis in Human Hepatocellular Carcinoma J5 Cells: Critical Role of C a + 2 -Dependent Pathway

Figure 1

The cell survival of J5 cells after curcumin treatment. J5 cells were treated with 25 μM curcumin for 0, 12, 24, and 48 h and photographed with phase-contrast microscope (a) or with various doses of curcumin for 24 h, and cell viability was determined by trypan blue exclusion assay (b). Each data point is the mean ± SE of three experiments. ** stands for significant difference as compared with that of the control.
