| Abstract | Purpose: To investigate the effect of α-momordicine (α-MMC) on liver cancer cell proliferation and apoptosis, and to elucidate the mechanisms of action involved. Methods: In in vitro experiments, hepatoma cell lines were used, while nude mice with hepatocellular carcinoma were used for in vivo studies. Cancer cell proliferation was determined using MTT assay while apoptosis was assayed by flow cytometry and TUNNEL staining. Gene expression was determined with real-time polymerase chain reaction (RT-PCR), while protein expression levels were assayed by Western blot, immunohistochemistry and immunofluorescence. Results: Alpha-MMC decreased HCC cell viability dose-dependently (p < 0.05). In HepG2 cells, G2/M cell cycle was halted after 48 h intervention with 1.24 mg/mL α-MMC. However, at G0/G1 phase, αMMC at doses of 1.06 and 0.92 mg/mL caused cell cycle arrest of HCC-LM3 and SMMC-7721 cells. In vivo studies showed that after establishment of the nude mice liver cancer model, exposure to α-MMC at a dose of 0.70 mg/kg or 2.08mg/kg for 4 weeks reduced the size of liver cancer in the treatment group, relative to control group; mean diameter of liver cancer decreased from 2.16 to 0.51 cm, while mean volume decreased from 1.185 to 0.085 cm3 . Moreover, α-MMC increased apoptosis level in liver cancer tissues in nude mice, and down-regulated the expressions of P-AKT, RAGE, MMP-9 and HMGB1, but upregulated Bax/Bcl2 ratio (p < 0.05). Conclusion: α-MMC inhibits cancer cell growth and proliferation, and facilitates their apoptosis by positively regulating the ratio of Bax/Bcl2. The anti-liver cancer effect of α-MMC is mediated via HMGB1-RAGE and AKT signaling pathways |

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.
