| Abstract | To investigate the effect of miR-18a on the regulation of the insulin-like growth factor (IGF-1) during growth of antlers in sika deer, miRNA Chip analysis, Target Scan and real-time PCR analysis were used to identify miRNAs that bind to the 3′-UTR of IGF-1. An miR-18a mimic was transfected into antler cartilage cells and the expression levels were quantified by real-time PCR. Dual luciferase assays revealed that miR-18a binds to the 3′-UTR of the IGF-1 gene thus indicating this to be a target gene regulated by miR-18a. MTT assays and cell-cycle analyses confirmed that miR-18a significantly inhibited proliferation of cartilage cells. In contrast, transfection of miR-18a inhibitors increased proliferation. Furthermore, Western blot analysis showed that over-expression of miR-18a down-regulated IGF-1 protein levels while IGF-1 expression was increased after transfection of miR-18a inhibitors. Thus, miR-1 down-regulated IGF-1 expression thus implicating miR-18a as an important regulator of antler proliferation. |

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.
