Association between MMP-12-82A/G polymorphism and cancer risk: a meta-analysis.

ABSTRACT: BACKGROUND:Numerous studies have focused on the association between MMP-12-82A>G polymorphism and cancer risk, but produced inconsistent results. Therefore, we performed a meta-analysis of case-control study to evaluate the association of MMP-12-82A>G polymorphism and cancer risk. METHODS:A systematic literature search was conducted among PubMed, Web of Science, Science Direct, China National Knowledge Infrastructure (CNKI) and Wangfang databases updated on May 1st, 2015. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate the strength of association between this polymorphism and cancer risk. RESULTS:A total of seventeen case-control studies with 7,450 cases and 7,348 controls were identified and analyzed. Overall, there was no statistically significant association between MMP-12-82A>G polymorphism and increased risk of cancer under all genetic models. Subgroup analysis by ethnicity observed that there is no strong relationship between MMP-12-82A>G polymorphism and cancer risk among Asian and European populations. Furthermore, stratified analysis based on the source of control revealed no statistically significant association between MMP-12-82A>G polymorphism and cancer risk either in hospital-based or population-based studies. However, when we stratified analysis based on cancer type, significant association was found in ovarian cancer, but not in other types of cancer. CONCLUSION:This meta-analysis suggests that MMP-12-82A>G polymorphism is not significantly associated with overall cancer risk. However, MMP-12-82A>G polymorphism may increase the susceptibility to ovarian cancer.

Project description:BackgroundMatrix metalloproteinase-1 (MMP-1) plays an important role during the destruction of periodontal tissue. Although multiple studies had focused on the association between MMP-1 g.-1607dupG and periodontitis susceptibility, the results remained inconclusive. The purpose of this meta-analysis was to explore its role in the development of periodontitis.MethodsRetrieved studies from Pubmed, Web of Science, Medline and Google Scholar Search regarding MMP-1 g.-1607dupG and periodontitis susceptibility were included into the final analysis with definite selection and exclusion criteria. Overall and stratified analyses based on disease type, severity, ethnicity and smoking status were performed. Odds ratio (OR) and 95% confidence interval (CI) were used to evaluate the association between MMP-1 g.-1607dupG and periodontitis susceptibility, while Q test and Egger's test were adopted respectively to assess heterogeneity among studies and publication bias.ResultsA total of 1580 periodontitis cases and 1386 controls in 11 case-control studies were included in the meta-analysis. The pooled results showed significant association between periodontitis susceptibility and MMP-1 g.-1607dupG polymorphism in homozygote (2G/2G versus 1G/1G, OR?=?1.50, 95% CI?=?1.02-2.20) and dominant model analysis (2G/2G+2G/1G versus 1G/1G, OR?=?1.28, 95% CI?=?1.04-1.57). For subgroups by type of periodontitis, increased risk of chronic periodontitis was observed on heterozygote (2G/1G versus 1G/1G, OR?=?2.01, 95% CI?=?1.58-2.56) and dominant model (OR?=?1.27, 95% CI?=?1.03-1.57). Furthermore, similar association was also detected in severe chronic periodontitis (2G/2G versus 1G/1G, OR?=?2.15, 95% CI?=?1.35-3.43; 2G/2G+2G/1G versus 1G/1G, OR?=?1.64, 95% CI?=?1.12-2.39; 2G/2G versus 2G/1G+1G/1G, OR?=?1.86, 95% CI?=?1.31-2.64).ConclusionsOur meta-analysis demonstrated that MMP-1 g.-1607dupG polymorphism was associated with chronic periodontitis, especially the severity of the disease condition.

Project description:BackgroundOsteoarthritis (OA) is a common disease characterized by articular cartilage degeneration and secondary hyperosteogenesis. Genetic factors are associated with the occurrence of OA. While several studies have shown that the matrix metalloproteinase-1- (MMP-1-) 1607 1G/2G (rs1799750) polymorphism may be related to the occurrence and development of OA, there is inconsistency in the literature. To better estimate the relationship between the MMP-1 gene polymorphism and OA, a comprehensive meta-analysis of relevant literature was carried out.ResultsIn total, seven studies comprising 1245 OA patients and 1230 controls were included in this meta-analysis. The combined results revealed no significant association between the MMP-1-1607 1G/2G polymorphism and risk of OA in the five genetic models. However, after Bonferroni correction, the results of subgroup analysis revealed a significant correlation between the MMP-1-1607 1G/2G polymorphism and OA susceptibility in the temporomandibular joint (TMJ) OA subgroup (allelic: 2G vs. 1G: OR = 1.575, 95%CI = 1.259-1.972, P < 0.01; recessive: 2G2G vs. 1G1G+1G2G: OR = 2.411, 95%CI = 1.658-3.504, P < 0.01; and homozygote: 2G2G vs. 1G1G: OR = 2.313, 95%CI = 1.341, 3.991, P = 0.003), the younger subgroup (aged less than 60 years; allelic: 2G vs. 1G: OR = 1.635, 95%CI = 1.354, 1.974, P < 0.01; dominant: 2G1G+2G2G vs. 1G1G: OR = 1.622, 95%CI = 1.158, 2.271, P = 0.005; recessive: 2G2G vs. 1G1G+1G2G: OR = 2.209, 95%CI = 1.718, 2.840, P < 0.01; and homozygote: 2G2G vs. 1G1G: OR = 2.578, 95%CI = 1.798, 3.696, P < 0.01), the larger subgroup (N > 300), and the hospital-based case-control study (HCC) subgroup. The sensitivity analysis suggested that the results of the meta-analysis were stable and reliable. Begg's funnel plot and Egger's test indicated that there was no publication bias in this study.ConclusionOur meta-analysis indicated that although the MMP-1-1607 1G/2G polymorphism was not significantly associated with OA susceptibility among the whole sample, it played a key role in the etiology and development of TMJ OA and OA in people aged less than 60 years.
