A Meta-Analysis of Association Between the MMP-13 rs2252070 Promoter Polymorphism and Cancer Risk

Abstract Background Originally detected in breast cancer tissue, MMP-13 has been showed to be closely related to cancer development. Increasing evidence has also suggested that rs2252070, one of its SNP, can profoundly influence cancer risk by regulating the expression while the conclusion still remained controversial. Therefore, this meta-analysis was conducted to assess the carcinogenesis effect of this SNP quantitatively. Methods Studies about association between rs2252070 polymorphism and cancer risk by March 15, 2020 had been collected in PubMed, Web of Science, Cochrane Library and CNKI. R scripts and STATA software were applied to calculate estimates. Pooled ORs and corresponding 95% CIs were used to evaluate the strength of association. Results Twenty studies meeting pre-defined criteria were retrieved for the final statistical analysis, including 8,215 cancer patients and 8,480 healthy controls. The pooled estimates revealed no statistical significance for the association between this polymorphism and the risk of cancer in all 5 genetic models. Similarly, no significance had been detected in stratified analyses by region, cancer type, sample size and genotyping method. Conclusion The association between MMP-13 rs2252070 and carcinogenesis was not statistically significant. To elucidate this conclusion, future studies including gene-gene and gene-environment interaction are needed to verify the study results.
