To explore the effect of ochratoxin A (OA) on the apoptosis of human kidney cell (HKC) in vitro, HKC were treated with OA at different concentrations for 24 h and harvested for detection. The apoptosis rate of HKC was detected with flow cytometry (FCM), the expression of caspase-3 and the level of JNK/p-JNK were determined with immunocytochemical staining and Western blot respectively. FCM analysis showed that the apoptosis rate of HKC was evaluated in OA treated group. Both caspase-3 expression and p-JNK l...
