Abstract

EC (esophageal cancer) is a common cancer among people in the world. The molecular mechanism of FAM196B (family with sequence similarity 196 member B) in EC is still unclear. This article aimed to clarify the role of FAM196B in EC. The expression of FAM196B in EC tissues was detected using qRT-PCR. The prognosis of FAM196B in EC patients was determined by log-rank kaplan-Meier survival analysis and Cox regression analysis. Furthermore, shRNA was used to knockdown the expression of FAM196B in EC cell lines. MTT, wound healing assays and western blot were used to determine the role of FAM196B in EC cells. In our research, we found that the expression of FAM196B was up-regulated in EC tissues. The increased expression of FAM196B was significantly correlated with differentiation, lymph node metastasis, stage, and poor survival. The proliferation and migration of EC cells were inhibited after FAM196B-shRNA transfection in vitro and vivo. The western blot result showed that FAM196B could regulate EMT. These results suggested that FAM196B severs as an oncogene and promotes cell proliferation and migration in EC. In addition, FAM196B may be a potential therapeutic target for EC patients.
