| Abstract | In this study, we investigated the therapeutic efficacy of EGFR2R-lytic hybrid peptide for the treatment of liver metastasis from colon carcinoma. The cytotoxic activity of the hybrid peptide against luciferase-expressing human colon cancer (HCT-116-luc) cells was determined by the WST-8 assay. The experimental mouse model of liver metastases was generated by splenic injection of HCT-116-luc cells. The hybrid peptide was intravenously injected into mice the day after cell implantation at a dose of 5 mg/kg and this was repeated on alternate days for a total of 7 doses. Saline-treated mice were used as controls. Tumor growth and therapeutic responses were monitored by an IVIS imaging system. It was shown that the hybrid peptide exhibited potent cytotoxic activity against HCT-116-luc cells and the liver metastases were significantly reduced after intravenous injections of hybrid peptide compared with controls. Furthermore, Kaplan–Meier analysis showed that hybrid peptide-treated mice had significantly longer survival than controls. In addition, bright-field and ex vivo imaging of liver tissue revealed that mice treated with the hybrid peptide had significantly fewer tumors compared with controls. These results demonstrated that the EGFR2R-lytic hybrid peptide is a potential treatment option for patients with colorectal cancer metastases in the liver. |

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.
