| Abstract | Gastric carcinogenesis is a multiple-stage process. It is believed that a premalignant lesion often precedes or accompanies gastric cancer, although the underlying mechanisms have not been fully elucidated. Here, we revealed that REG I was frequently overexpressed not only in gastric cancer tissues, but also in the intestinal metaplastic and atypical dysplasia gland, which are considered precancerous lesions, in 102 patients. To investigate the role of REG I in gastric cancer, we employed siRNA-mediated silencing techniques and found that the downregulation of REG I significantly inhibited gastric cancer cell proliferation, whereas overexpression of REG I promoted proliferation. In addition, REG I appeared to have an anti-apoptotic effect in gastric cancer cells, which was associated with the Bad/Bcl-xL/caspase-3 pathway. Furthermore, gastrin was found to activate REG I expression and nuclear translocation of ß-catenin in gastric cancer cells. Thus, these data suggest that REG I , a potential downstream of gastrin, may be involved in gastric carcinogenesis. |

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.
