ABSTRACT
Objective To study the effects of restructuring tissue inhibitor of matrix metatloproteinase-3 (rhTIMP-3) in combination with cisplatin (DDP) on the growth and apoptosis of A549 lung cancer cell line.Methods We made individual and combined use of different concentrations of rhTIMP-3 and DDP on A549 cells.Methyl thiazoyl terazolium (MTT) colorimetry was used to analyze cell growth inhibition,and flow cytometry technique was used to determine the cell cycle distribution and apoptosis rate.Results rhTIMP-3 and DDP both could inhibit the proliferation of A549 cells.rhTIMP-3 exerted its effect in the time-and concentration-dependent manners while DDP did so in the concentration-dependent manner;both induced the apoptosis of A549 cells.rhTIMP-3 could make the cells stay in S and G2/M phases,and DDP made the cells stay in S phase.The combination of them obviously strengthened the inhibition of A549 cell growth,and had obvious synergy in inducing apoptosis.Conclusion Both rhTIMP-3 and DDP can inhibit the proliferation of A549 cells and induce their apoptosis.The combined use of them not only can increase the inhibition of cell growth but also has synergy in inducing cell apoptosis.
