| Abstract | The aim of the present study was to examine the expression of hepatocyte growth factor (HGF) in breast cancer and its effect on prognosis and sensitivity to chemotherapy. Immunohistochemistry was conducted to determine the expression of HGF in 125 breast cancer patients. The correlation between the expression level of HGF and the effect of preoperative chemotherapy or 5year survival rate was then investigated. The human breast cancer cell line, MCF7, was transfected with a HGFsmall interfering (si)RNA interference sequence. Reverse transcription quantitative polymerase chain reaction and western blot analysis were used to confirm the interference efficiency of HGFsiRNA. An MTT assay was used to detect the proliferative activity of MCF7 cells following silencing of HGF and during coculture with epirubicin (EPI) at different concentrations. HGF was highly expressed in breast cancer patients and was not associated with patient age, location, size or hormone receptor status of the tumor (P>0.05), however, HGF expression was associated with tumornodemetastasis (TNM) clinical stage, histological grade, lymph node metastasis and prognosis (P<0.05). The efficiency of chemotherapy in HGF negative patients (90%) was significantly higher (P<0.05) compared with HGF positive patients (68.75%). Following successful downregulation of HGF by HGFsiRNA, the tolerance to EPI decreased in MCF7 cells. In conclusion, HGF was highly expressed in breast cancer cells and was closely associated with lymph node metastasis, prognosis and sensitivity to chemotherapy. Therefore, HGF may be a potential indicator of the prognosis and effectiveness of chemotherapy for breast 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.
