| Abstract | Aim: To investigate the correlations of MMP-2 and TIMP-2 polymorphisms with the risk and prognosis of gastric cancer (GC). Methods: With an incorporation of 254 GC patients in the case group and 250 healthy subjects enrolled as the control group, this experiment was conducted. Denaturing high performance liquid chromatography method was adopted to detect all genotypes under partial denaturation, haloptype analysis was completed with the Shesis software. Serum MMP-2 and TIMP-2 levels were determined by the immunohistochemical semi-quantitative analysis. The follow-up examination was conducted after the patients had completed systemic therapy and discharged. Results: The distribution frequencies of MMP-2-735C/T locus genotypes between groups were compared (P > 0.05). However, the distributions of alleles and genotype frequencies of MMP-2-1306C/T, TIMP-2-303G/A and -418G/C all exhibited statistical difference (all P < 0.05). The gene polymorphism of MMP-2-1306C/T was statistically correlated with the expression of MMP-2 protein (P < 0.05); the same result was also found regarding TIMP-2-303G/A (P < 0.05). The haplotype analysis revealed that the CGC frequency of the case group was apparently higher than that of the control group (P < 0.05), the positive survival rate of CGC was apparently lower than the negative one. Conclusion: MMP-2-1306C/T, TIMP-2-303G/A and -418G/C variants might be correlated with GC susceptibility. Serum MMP-2 and TIMP-2 protein levels might be associated with GC susceptibility; Additionally, CGC haplotype might be the risk factor of GC. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
