ABSTRACT
Objective To investigate the effect of triptolide (TP) on the apoptosis of ovarian cancer cell line SKOV-3 and its molecular mechanism.Methods Ovarian cancer cell line SKOV-3 was cultured and treated with different doses of TP (1 × 10-6 mg/ml,1 × 10-5 mg/ml,1 × 10-4 mg/ml,1 × 10-3 mg/ml),Iscoves modification of DMEM (IMEM) medium without TP was negative control.At the 12 h,24 h and 48 h after treatment,apoptosis rate was determined by terminal dexynucleotidyl transferase (TdT) mediated dUTP nick end labeling (TUNEL) kit.At the 48 h after treatment,mRNA expression of apoptosis molecules and invasion molecules were determined by fluorescence quantitative polymerase chain reaction (PCR) kit.Results (1) At the 12 h,24 h,and 48 h after treatment with different doses of TP,at the same treatment time,the higher the TP dose was,the higher the apoptosis rate of SKOV-3 cells was;at the same treatment dose,the longer the treatment time was,the higher the apoptosis rate of SKOV-3 cells was;and TP increased the apoptosis rate on dose dependent and time dependent manner;(2) After 48 h treatment with different doses of TP,the higher the TP dose was,the higher the mRNA expression of cytochrome C (CytC),Bax,and Caspase-3 was,the lower the mRNA expression of Bcl-2,matrix metalloproteinases (MMP)2,MMP7,MMP9,N-cadherin,and vimentin was;TP increased mRNA expression of CytC,Bax,and Caspase-3 and decreased mRNA expression of Bcl-2,MMP2,MMP7,MMP9,N-cadherin,and vimentin on dose dependent manner.Conclusions TP can induce the apoptosis of ovarian cancer cells,activation of mitochondrial apoptosis pathway and inhibition of cell invasion are molecular mechanism of TP promoting apoptosis.
