| Abstract | Glioma is a severe and highly lethal brain cancer, a malignancy largely stemming from growing in a relatively restrained area of the brain. Hence, the understanding of the molecular regulation of the growth of glioma is critical for improving its treatment. MicroRNA has become a hotspot in research on diseases, especially in the initiation and progression of different types of cancer. However, the molecular function and mechanisms of miR-508-5p in gliomagenesis are still unclear. The aim of this study was to investigate miR-508-5p expression in glioma and determine its effects on proliferation. miR-508-5p expression levels, both in glioma cell lines and in tissue, were significantly lower than in a normal human astrocyte cell line or adjacent tissues. Cell growth was analyzed using a MTT assay and over-expression of miR-508-5p was found to decrease glioma cell growth. Moreover, a bioinformatic analysis was performed, showing that glycoprotein non-metastatic melanoma B (GPNMB) was a direct target for miR-508-5p in glioma cells. Furthermore, in vivo treatment with miR-508-5p reduced GPNMB protein levels in the tumor. Additionally, overexpression of GPNMB without 3′-UTR partially reversed the cell growth arrest induced by miR-508-5p over-expression in glioma cells. In conclusion, these results indicate that increased expression of miR-508-5p might be related to glioma progression, indicating a potential role of miR-508-5p for clinical therapy. |

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.
