GSK343 alleviated LPS-induced ATII apoptosis. (A,C) Flow cytometry was employed to detect the apoptosis rate of ATIIs. The cells were equally divided into the Con group, LPS group, GSK343 group, and LPS + GSK343 group. We evaluated the proportion of apoptotic cells (Q2 + Q3) in each group. (B) The effect of GSK343 on the expression of TNF-α in LPS-induced PBMCs. Data are presented as mean ± SD (n = 3 per group) of the representative data from three independent experiments; *** p < 0.005, **** p < 0.001, ns: no significance, ### p < 0.005, #### p < 0.001. The asterisk (*) shows that the group is statistically different from the Con group.
