Objective To investigate the effect of S100A4 silencing on tumor related gene COX-2,bcl-2,Surviving,MMP-9 mRNA expressions of pancreatic cancer BxPC-3,AsPC-1 cells,and explore their relationship.Methods Small interfering RNA interfering S100A4 gene (siRNA-S100A4) was applied to transfect human pancreatic cancer BxPC-3,AsPC-1 cells,and nonhomologous siRNA-C was used as negative control,and cells without transfection were used as control group.The expressions of S100A4,COX-2,Survivin,MMP-9,bcl-2 mRNA after interference were detected by using RT-PCR.Results S100A mRNA expressions of BxPC-3's control group,siRNA-C group,siRNA-S100A4 group were 0.661 ± 0.023,0.659 ± 0.043,0.379 ± 0.039,and expressions of COX-2 mRNA were 0.760 ± 0.026,0.830 ± 0.017,0.443 ±0.006,and expressions of Survivin mRNA were 0.948 ± 0.049,0.909± 0.081,0.068 ± 0.006,and expressions of bcl-2 mRNA were 0.462 ±0.018,0.421 ±0.049,0.184 ±0.025,and expressions of MMP-9 mRNA were 0.813 ± 0.008,0.908 ± 0.063,0.246 ± 0.027.S100A mRNA expressions of AsPC-I's control group,siRNA-C group,siRNA-S100A4 group were 0.641 ± 0.042,0.626-± 0.053,0.320 ± 0.081,and expressions of COX-2 mRNA were 0.727 ± 0.021,0.743 ± 0.025,0.560 ± 0.035,and expressions of Survivin mRNA were 0.994 ± 0.032,0.984 ± 0.049,0.063 ± 0.005,and expressions of bcl-2 mRNA were 0.458 ±0.004,0.537 ± 0.046,0.181 ± 0.007; and expressions of MMP-9 mRNA were 0.698 ± 0.011,0.718 ± 0.073,0.199± 0.013.The expressions of S100A,COX-2,Survivin,bcl-2,MMP-9 mRNA in groups with siRNA-S100A4 transfection were significantly lower than those of siRNA-C group and control group (P ＜0.01),but the difference between siRNA-C group and control group was not statistically significant.Conclusions S100A4 plays a role in the pathogenesis of pancreatic cancer through up-regulation of COX-2,Survivin,bcl-2,MMP-9 expressions.
