| Abstract | Resveratrol is a natural polyphenolic stilbene widely found in grapes, berries, and other plants. Caloric restriction-like effects of resveratrol have been associated with suppressive and apoptotic effects on adipocyte differentiation in vitro when used at high doses (≥20 µM), which may not be achievable in vivo. The aim of this study was to investigate the effects of resveratrol at physiologically achievable low doses (1 and 10 μM) on 3T3-L1 adipocyte differentiation.3T3-L1 preadipocytes were differentiated into adipocytes using a modified adipogenic cocktail in the presence or absence of resveratrol. Differentiation was determined by lipid accumulation and mRNA expression of marker genes. Activation of glucocorticoid receptor (GR) and peroxisome proliferator-activated receptor γ (PPARγ) was determined by transcription factor-mediated reporter assays and mRNA expression of target genes. Protein samples were collected for the study of AMPK activation.Resveratrol at physiologically achievable doses (1 and 10 µM) significantly enhanced 3T3-L1 adipocyte differentiation although the effect was less pronounced compared with that achieved under optimal differentiation cocktail in vitro. Resveratrol (1–50 µM) dose dependently activated or synergized with the synthetic ligand or adipogenic treatment to activate GR and PPARγ. However, resveratrol induced cell death when used at doses above 10 µM in differentiating cells.Our results report for the first time that resveratrol at physiologically achievable doses (1 and 10 µM) enhances 3T3-L1 adipocyte differentiation, which supports the emerging paradigm that enhanced adipocyte differentiation may be associated with caloric restriction-like metabolic effects for resveratrol. |

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.
