| Abstract | GYY4137 is a watersoluble, small molecule hydrogen sulfide (H2S)release agent that possesses potent cardioprotective and antiinflammatory properties in experimental models. Coxsackie virus B3 (CVB3) infection commonly causes viral myocarditis, which mainly involves immune cell infiltration, eventually resulting in heart failure. In the present study, the effects and underlying mechanisms of GYY4137 treatment of CVB3induced myocarditis were investigated. The effects of GYY4137 on CVB3induced nuclear factorkappa B (NFκB) activity were examined by western blotting, immunofluorescence and electrophoretic mobility shift assay. Mitogenactivated protein kinase (MAPK) signaling protein expression levels were detected by western blotting. Cardiomyocyte damagerelated enzyme activities, such as lactate dehydrogenase (LDH) and creatine kinase MB (CKMB), were measured by ELISA, as well as the production of proinflammatory cytokines. The results revealed that GYY4137 suppressed CVB3induced secretion of LDH, CKMB and proinflammatory cytokines, such as tumor necrosis factor , interleukin (IL)1ß and IL6. Furthermore, the activation of NFκB and the IκB degradation induced by CVB3 were also inhibited by GYY4137. Notably, the phosphorylation of p38, ERK1/2 and JNK1/2 induced by CVB3 was also inhibited by GYY4137. In conclusion, the data demonstrate that GYY4137 exerts antiinflammatory effects in CVB3infected cardiomyocytes. This antiinflammatory mechanism may be associated with suppression of NFκB and MAPK signaling pathway activation. |

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.
