Fig. 6From: Antitumor agent yatein from Calocedrus formosana Florin leaf induces apoptosis in non-small-cell lung cancer cellsROS levels of A549 and CL1-5 cells after treatment with 5 μM yatein for 1, 3, 6, and 12 h. Black line: unstained cells, red line: control group, and green line: yatein treatment group. The results represent the mean ± SD (n = 3); different capital and lowercase letters indicate significant differences among each group in the A549 and CL1-5 cells, respectively (p < 0.05). p values were calculated by one-way ANOVA, followed by shuffle testBack to article page
