APS pretreatment protects HK-2 cells from cisplatin exposure. (a) HK-2 cell viability was measured by CCK8. Cells were incubated with different concentrations of cisplatin for 24 h from 0 (control) to 50 μmol/L. (b) Cell viability of HK-2 cells treated with APS at different concentrations for 24 h from 0 (control) to 200 μg/mL. (c) Cell viability of HK-2 cells treated with APS and cisplatin. HK-2 cells were pretreated with APS at different concentrations for 24 h and then were treated with 20 μmol/L cisplatin for 24 h. Values are means ± SEM (n = 3). ^∗∗P < 0.01, versus control; ^##P < 0.01, versus the cisplatin alone-treated group.
