| Abstract | In this study, we have investigated the intracellular level of reduced glutathione, cell-cycle phase distribution, and microfilament and microtubule structures in normal (3T3) and transformed (3T3-SV40) fibroblasts exposed to alpha-lipoic acid (ALA) in concentrations of 0.7–5 mM. It was found that ALA treatment increased the glutathione content in transformed cells, but did not affect its level in normal cells; moreover, it also induced the cell-cycle arrest of 3T3 cells (but not 3T3-SV40 cells) and disrupted actin microfilaments in cells of both lines. The ALA effect was compared to that of N-acetylcysteine (NAC), another antioxidant we examined previously. The findings allow us to assert that each of these antioxidants impacts on distinct target molecules in normal and transformed cells and activates different signal and metabolic pathways in these cells. However, intermediate steps of ALA and NAC action may be common (altered intracellular level of glutathione, reorganization of actin cytoskeleton, etc.). |

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.
