| Abstract | Jaceosidin is a flavonoid isolated from Artemisia vestita that has been reported to possess anti-tumor and anti-proliferative activities in many cancer cells. In this study, we investigated the anti-tumor activity of jaceosodin in renal carcinoma cells. Jaceosidin induced apoptosis in multiple human renal carcinoma cells (Caki, ACHN, A498, and 786-O), lung cancer cells (A549) and glioma cells (U251MG). In contrast, jaceosidin does not induce apoptosis in normal human umbilical vein cells (EA.hy926). Apoptotic cell death was associated with the activation of caspase-3 and cleavage of poly (ADP-ribose) polymerase. Treatment with jaceosidin also caused loss of mitochondrial membrane potential (MMP) and Bax activation, which led to the release of cytochrome c into the cytosol. We also found that jaceosidin downregulated Mcl-1 and c-FLIP expression at the transcriptional level and that ectopic expression of Mcl-1 and c-FLIP blocked jaceosidin-induced apoptosis. Cumulatively, our results suggest that jaceosidin induces apoptosis in renal carcinoma cells through Bax activation and reduces Mcl-1 and c-FLIP expression. |

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.
