| Abstract | The associations between two common polymorphisms in microRNA genes (miR-146a, dbSNP: rs2910164; miR-196a-2, dbSNP: rs11614913) and gastric cancer risk have frequently been examined; however, the results have often been controversial. This meta-analysis was performed to clarify the association between the two polymorphisms and gastric cancer risk. The literature search primarily utilized PubMed, Embase, SinoMed, and Wanfang databases to identify eligible studies. Odds ratios (ORs) with their 95% confidence intervals (CIs) were analyzed to investigate possible correlations. Subgroup analyses of ethnicity as well as source of controls were also performed. The correlation analysis was based on 11 studies, containing 4690 patients and 6066 controls for miR-146a (C>G) together with 1911 patients and 2484 controls for miR-196a-2 (T>C). For the miR-146a polymorphism, the values of the ORs and 95%CIs were >1, suggesting that a correlation exists. In subgroup analysis of source of controls, a correlation was also identified in the Asian subgroup. However, in Caucasians the ORs and 95%CIs were not distributed on the same side of the critical value 1, contra-indicative of a correlation in this group. For the miR-196a-2 polymorphism, the ORs with 95%CIs of both overall and subgroup analyses were also not restricted to >1 or Ë 1. In summary, the results suggested that the miR-146a rs2910164 polymorphism was related to gastric cancer risk in Asians but not in Caucasians, and no distinct correlation seemed to exist between the miR-196a-2 rs11614913 polymorphism and the risk of gastric cancer. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
