| Abstract | Lung cancer is one of the most common and serious types of cancer. Till now, the treatment of lung cancer has been unsatisfactory, which is associated with poor prognosis and high mortality. Therefore, there is an urgent requirement to investigate the molecular mechanisms underlying lung tumorigenesis. To study the potential function of miR-10b involved in the regulation of lung tumors, we monitored NSCLC cell behaviour including proliferation, apoptosis and cell cycle using CCK-8 and flow cytometry analysis. Real-time PCR was used to detect the expression levels of miR-10b in 75 NSCLC patients' tissues and Western blot was also used to analyze the expression level of genes correlated with apoptosis in NSCLC cells. miR-10b expression levels were higher in NSCLC tissues compared with an adjacent normal tissue control. Silencing of miR-10b inhibited cancer cell progress by arresting cell cycle progression in the G0/G1 phase and promoted apoptosis in NSCLC cells. Western blot analysis of miR-10b-silenced cells revealed up-regulation of apoptosis-inducing members Fas, FasL, Bax and caspase 3, and down-regulation of apoptosis-inhibiting factors Bcl-2 and PCNA. And, a significant inverse correlation between the level of miR-10b and klotho was observed, which has been demonstrated to be a novel tumor suppressor gene. A further in vivo tumor formation study in nude mice indicated that inhibition of miR-10b in lung cancer cells delayed the progress of tumor formation. These findings indicated that miR-10b might serve as a useful potential target for treatment of NSCLC. |

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.
