| Abstract | Prior studies have suggested that a high intake of isoflavonoids is associated with a protective effect against hormone-related cancers, such as colorectal cancer (CRC). Calycosin, a main component of isoflavones, has been shown to suppress the growth of hormone-dependent tumors through an ERβ-mediated signaling pathway. However, the effects of calycosin on CRC remain unclear. In this study, we aimed to investigate the anti-tumor activities of calycosin on CRC and its potential mechanism. HCT-116 cells were treated with calycosin. Cell proliferation, apoptosis and invasiveness were measured by MTT assay, flow cytometry and transwell invasion assay, respectively. mRNA levels of ER beta (ERβ) and miR-17 were quantified by real-time PCR. Protein expressions of ERβ and phosphatase and tensin homolog deleted on chromosome ten (PTEN) were determined by western blotting. We found that calycosin significantly induced apoptosis, and inhibited proliferation and invasiveness of HCT-116 cells in a dose-dependent manner. In addition, ERβ expression significantly increased in calycosin-treated HCT-116 cells, followed by a decrease of miR-17, and up-regulation of PTEN. Our results indicate that calycosin has an inhibitory effect on CRC, which might be obtained by ERβ-mediated regulation of miR-17 and PTEN expression. |

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.
