| Abstract | Osteosarcoma is a highly malignant cancer that often appears in teenagers. It is the most frequently occurring primary bone tumor, and can easily metastasize, resulting in high mortality. MicroRNAs express abnormally in osteosarcoma, and may function as oncogenes or tumor suppressors. Recent studies showed that microRNA184 (miR-184) is abnormally expressed in multiple tumors, and is involved in tumor cell growth, differentiation, invasion, and metastasis. Nevertheless, the role of miR-184 in osteosarcoma cells remains unknown. We evaluated the expression and function of microRNA184 in osteosarcoma cells. SOSP-M osteosarcoma cells were divided into normal control, miR-184 mimic, and miR-184 inhibitor groups. Real-time PCR was applied to detect miR-184 expression. The 3-(4,5-dimethylthaizol-2-yl)-2,5-diphenyltetrazolium bromide assay was used to evaluate cell proliferation. Transwell assays were performed to detect changes in cell invasion ability. Compared with the control group, miR-184 expression was significantly increased in the miR-184 mimic group (P < 0.05). After miR-184 inhibitor transfection, miR-184 expression was obviously reduced (P < 0.05). Tumor cell proliferation was enhanced in the miR-184 mimic group (P < 0.05), whereas miR-184 inhibition suppressed cell proliferation (P < 0.05). Furthermore, tumor cell invasion increased after miR-184 mimic transfection (P < 0.05), and decreased after inhibiting miR-184 (P < 0.05). MiR-184 promotes tumor cell proliferation and invasion, and may represent a new biological target for osteosarcoma. |

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.
