| Abstract | Previous studies have demonstrated the cancer-type specific role of forkhead box protein A1 (FOXA1) in human malignancies. However, the clinical significance of FOXA1 and its biological function in gastric cancer remain unknown. In this study, the expression of FOXA1 in 80 pairs of gastric cancer tissues and corresponding non-tumor tissues was analyzed using immunohistochemistry and quantitative real-time polymerase chain reaction. We found that the levels of FOXA1 protein and mRNA in gastric cancer tissues were significantly higher than those in matched tumor-adjacent tissues. Furthermore, clinical association analysis indicated that the positive expression of FOXA1 was associated with adverse clinicopathological characteristics of gastric cancer patients including poor tumor differentiation, large tumor size, and advanced tumor-node-metastasis tumor stage. Notably, gastric cancer patients with positive expression of FOXA1 had a poorer 5-year overall survival and recurrence-free survival. In addition, FOXA1 knockdown remarkably inhibited cell proliferation and induced apoptosis in both SGC-7901 and MGC-803 cells. In vivo studies indicated that FOXA1 knockdown prominently suppressed tumor growth of gastric cancer in a nude mouse xenograft model. Mechanistically, we disclosed that the expression of Yes-associated protein was decreased accordingly after FOXA1 knockdown in both SGC-7901 and MGC-803 cells. Taken together, our data suggest that FOXA1 may serve as a promising prognostic indicator and an attractive therapeutic target of gastric 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.
