SHK-induced apoptosis depending on ROS generation. (A) The proportions of apoptosis cells of A549 were determined by flow cytometry using FITC annexin V/PI double staining assay after SHK treatments. (B) Expressions of Bcl-2, Bax and Cleaved Caspase-3 were measured by Western blot after SHK treatments. (C) The proportions of apoptosis cells of A549 were determined by flow cytometry after NAC pretreatment and SHK treatment using FITC annexin V/PI double staining assay. ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001 vs. Ctrl (control), ###P < 0.001 vs. SHK.
