| Abstract | Necrosis is programmed and is one of the main forms of cell death in the pathological process in cardiac diseases. MicroRNAs (miRNAs) have emerged as key gene regulators in many diseases. However, how miRNAs contribute to programmed necrosis is poorly defined. Here we report that miR-2861 and adenine nucleotide translocase 1 (ANT1) constitute an axis that regulates necrotic cell death in the heart. Our results show that ANT1 inhibits H2O2-induced cardiomyocytes necrosis. ANT1 also antagonizes myocardial necrosis in a mouse ischemia/reperfusion (I/R) model. We further demonstrate that miR-2861 directly binds to the coding sequence of ANT1 and suppresses the expression of ANT1 mRNA and protein. MiR-2861 induces necrotic cell death. In contrast, knockdown of miR-2861 attenuates H2O2-induced necrosis in cardiomyocytes. Also, miR-2861 knockdown protects heart from I/R injury and necrotic cell death in vivo. MiR-2861 regulates necrosis and myocardial infarction through targeting ANT1. Collectively, these data identify miR-2861 and ANT1 as two novel regulators of cardiomyocyte necrosis and myocardial infarction, and suggest potential therapeutic targets in treatment of cardiac diseases. |

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.
