| Abstract | The abnormal metabolism of cancer cells is a crucial feature of tumors and provides promising therapeutic targets for cancer treatments. Aerobic glycolysis in cancer cells, termed the Warburg effect, is a highlighted characteristic of cancerspecific metabolism. However, the effect of glycolysis inhibition on hepatocarcinogenesis remains to be elucidated. In the present study, the effects of the glycolysis inhibitor 2deoxyDglucose (2DG) on the Ndiethylnitrosamine (DEN)induced rat hepatocarcinoma model and its underlying mechanisms were investigated. It was observed that 2DG significantly delayed hepatocarcinogenesis and effectively prolonged survival time in the DENtreated rats. The glycolysis inhibitor, 2DG prominently decreased cell proliferation and increased cell apoptosis in the DENinduced rat hepatoma and had no evident impact on the pericarcinomatous liver tissues. Further investigation revealed that 2DG resulted in a reduction of glycolysis products, the compensatory increase of hexokinase 2 expression and a decrease in 6phosphofructo2kinase, pyruvate kinase M2 and lactate dehydrogenase A expression in the hepatoma tissues. The inhibition of glycolysis further suppressed the tricarboxylic acid cycle, fatty acid and cholesterol biosynthesis and ATP production, while it promoted autophagic activation. In addition, the in vitro study demonstrated that hypoxia, an important factor in the tumor microenvironment, may assist in increasing 2DGinduced inhibition of cell viability, cell cycle retardation and the decrease of colony formation ability in hepatoma cells. Taken together, the present results suggested that 2DG may inhibit hepatocarcinogenesis in the DENtreated rats via restricting cancer cell metabolism. This finding provides a promising measure in the prevention and treatment of hepatoma. |

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.
