摘要: 目的 探讨基质金属蛋白酶-2(MMP-2)及其组织抑制因子-2(TIMP-2)mRNA在膀胱癌组织中的表达,以及与膀胱癌侵袭、转移和复发的关系。方法 应用半定量PCR和实时定量PCR(RQ-PCR)方法,检测10例正常膀胱组织和45例膀胱移行细胞癌组织中MMP-2和TIMP-2 mRNA的表达。结果 半定量PCR显示MMP-2、TIMP-2在膀胱正常组织中均呈阴性表达,而在45例膀胱癌组织中,MMP-2阳性率为66.7%(30/45),TIMP-2为57.8%(26/45)。定量PCR检测显示MMP-2表达量随肿瘤病理分级和临床分期的升高而增加,在复发病例中也增加,其组间差异有统计学意义(P<0.05);TIMP-2的表达量随病理分级和临床分期的升高而降低,而且组间差异有统计学意义(P<0.05),而在初发复发病例的组间差异无统计学意义(P>0.05)。结论 MMP-2和TIMP-2对于膀胱癌的侵袭、转移和复发发挥了重要作用;MMP-2可能对判断膀胱癌的预后有一定的指导意义。

Abstract: Objective To investigate the expression of MMP-2 and TIMP-2 mRNA in transitional cell carcinoma of bladder and discuss their clinical significance.Methods Using RT-PCR and real time quantitative PCR(RQ-PCR)technique,the expression of MMP-2 and TIMP-2 mRNA of 45 cases of bladder carcinoma(tumor group)and 10 cases of normal bladder tissue(control group)were analyzed.Results MMP-2 and TIMP-2 were not expressed in control group.MMP-2 was expressed in 30 cases tumor samples and TIMP-2 was expressed in 26 cases.The expression of MMP-2 mRNA in superficial bladder cancer and G1 cancer were lower than that in infiltrating bladder cancer and G2-G3 cancer respectively.The differences were statistically significant(P <0.05).The expression of MMP-2 in recurrence group was higher than that in incipient group.TIMP-2 mRNA expression decreased with grades and stage.The expression of TIMP-2 in superficial bladder cancer and G1 cancer were higher than that in infiltrating bladder cancer and G2-G3 cancer respectively.There was statistical difference between two groups(P <0.05).TIMP-2 expression in incipient group was higher than that in recurrence group,but the difference was not significant(P>0.05).Conclusion These results suggest that MMP-2 and TIMP-2 play an important role in the invasive step of transitional cell carcinoma of bladder.MMP-2 may become a new approach to the diagnosis of bladder carcinomas.
