| Abstract | Alterporriol L, a new bianthraquinone derivative, was isolated from a marine fungus Alternaria sp. ZJ9-6B. The cytotoxic activity and anticancer mechanisms of alterporriol L towards breast cancer cells lines were detected using MTT assay, immunofluorescence, and flow cytometry. Simultaneously, the changes in morphological properties of cells were detected before and after treatment with alterporriol L by atomic force microscope (AFM) at a nanometer scale. MTT assay showed that alterporriol L could effectively inhibit the growth and proliferation, and there was a dose-dependent manner of cell death. Moreover, the alterporriol L could induce cancer cell apoptosis or necrosis. Furthermore, the reactive oxygen species, mitochondrial membrane potential, and cytosolic free calcium level were changed after treatment with alterporriol L, suggesting that alterporriol L played vital roles in breast cancer cells through destroying the mitochondrial. And all these alterations are in accord with changes of morphology detected by AFM, which suggested that the AFM is a useful tool to detect the morphological changes of the cancer 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.
