| Abstract | Cyr61 is associated with growth and progression of many types of tumors and is an independent poor prognostic indicator for oral cancer patients. Areca nut (AN) chewing is the most important etiological factor in the pathogenesis of oral cancer in India and many Southeast Asian countries. Yet, the molecular mechanisms involved in the AN-induced oral cancer remain largely unknown. In this study, we show that arecoline, a main alkaloid found in AN, stimulated Cyr61 synthesis in human gingival epithelial S-G cells. Constitutive overexpression of Cyr61 protein in oral epithelial cells during AN chewing may play a role in the pathogenesis of oral cancer. ERK inhibitor PD98059, N-acetyl-L-cysteine, Rho-associated protein kinase (ROCK) selective inhibitor Y-27632 and a geranylgeranyltransferase inhibitor reduced the arecoline-stimulated levels of Cyr61 protein by â¼31%, 47%, 65% and 100%, respectively. Lovastatin also completely inhibited arecoline-induced Cyr61 synthesis and the inhibition is dose-dependent. Decreased of geranylgeranylated proteins could be the mechanism that lovastatin regulates Cyr61 synthesis and lovastatin could serve as a useful agent in controlling AN-induced oral cancer. |

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.
