Abstract:
Objective To investigate the effects of pseudolaric acid B(PAB) on the invasiveness and metastatic activity of cervical cancer HeLa cells in vitro and the possible mechanism.Methods HeLa cells were divided into 5 groups: blank control group,DDP 3.125?g/ml group,20?mol/L PAB group,10?mol/L PAB group and 5?mol/L PAB group.The effect of PAB on invasive ability of HeLa cells was observed with a Transwell cell culture chamber.The mRNA expression of MMP22 and MMP29 in HeLa cells was detected by RT-PCR and the protein expression was detected by Western blotting.Results The average number of invaded HeLa cells was 15.60?2.45 in 20?mol/L PAB group and 20.14?2.48 in 10?mol/L PAB group,which was significantly lower than those in control group(46.50?4.70) and PAB 5?mol/L group(42.44?5.80,P
