| Abstract | Recent evidence indicates that microRNAs (miRNAs) play a key role in neurodegenerative diseases. However, little is known about how these small RNAs contribute to dopaminergic neuronal apoptosis. Here, we profiled the expression of miRNAs in MN9D cells with and without 6-hydroxydopamine (6-OHDA) treatment by miRCURY™ LNA microRNA arrays. We identified six miRNAs (miR-668-3p, let-7d-3p, miR-3077-3p, miR-665-5p, miR-99b-3p, and miR-323-3p) that were significantly lower and five miRNAs (miR-875, miR-207, miR-425-5p, miR-19b-3p, and miR-338-3p) that were significantly higher after 6-OHDA treatment. Among them, five have been demonstrated to be implicated in neurodegenerative diseases. Consistent with our prediction, the deregulated miRNA’s target mRNAs, such as peroxiredoxin III (Prx III) and Myc, also showed changes in their expression levels. Furthermore, using a dual-luciferase reporter assay, we confirmed that Prx III was a direct target gene of miR-875. Taken together, these findings demonstrate that changes in miRNA expression occur after 6-OHDA treatment and suggest that miRNAs and their predicted targets have a potential role in apoptosis of MN9D cells. |

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.
