Anti-cancer effects of sulfane sulfurs in HCC SNU398 cells. (A, B) The cells were treated with increasing concentrations of DATS or DMTS for 48 h. The cell viability was measured with CCK-8 assay. Data are expressed as mean ± SD of four independent experiments. * P < 0.05, ** P < 0.01 vs. Control group. (C) After the treatment with 400 μM DATS or DMTS, the intercellular content of sulfane sulfur was observed with SSP4 staining followed by photofluorography, and the cell nuclei were labeled using Hoechst 33324.
