Fig. 1From: Shikonin-induced necroptosis is enhanced by the inhibition of autophagy in non-small cell lung cancer cellsEffect of shikonin on the viability, cytotoxicity, and caspase 8 activity of A549 cells. Cells were treated with various concentrations of shikonin for 24 h. Viability and cytotoxicity were then measured by a multiplex assay, and caspase 8 activity was evaluated by a caspase 8 assay. Values are presented as mean ± SD of three independent experiments. *p < 0.05 compared to controlBack to article page
