Objective:The eukaryotic release factor 3a(eRF3a),a member of the eukaryotic peptide chain release factor family,is overexpressed in several types of cancer.This study aims to investigate the biological role and mechanism of eRF3a in the progression of liver cancer.Methods:Western blotting and RT-qPCR were used to detect the expression level of eRF3a in normal liver cells and liver cancer cells.The cell transfection experiments were performed to overexpress eRF3a levels in liver cancer cells HCCLM9 and Huh7,and then cell cycle and apoptosis experiments,Cell Counting Kit-8(CCK8),plate cloning,and Transwell experiments were done to evaluate the function of eRF3a in the progression of liver cancer.The Western blotting was done to explore the mechanism of eRF3a promoting the development of liver cancer.Western blotting and RT-qPCR were used to detect the expression level of eRF3a in normal liver cells and liver cancer cells.The cell transfection experiments were performed to overexpress eRF3a levels in liver cancer cells HCCLM9 and Huh7,and then cell cycle and apoptosis experiments,Cell Counting Kit-8(CCK8),plate cloning,and Transwell experiments were done to evaluate the function of eRF3a in the progression of liver cancer.The Western blotting was done to explore the mechanism of eRF3a promoting the development of liver cancer.Results:eRF3a was significantly highly expressed in liver cancer cells,and its expression level was negatively correlated with the clinical prognosis of patients.In addition,in vitro experiments showed that eRF3a could promote the proliferation and migration of liver cancer cells through the ERK and JNK signaling pathways.Conclusion:This study suggests that eRF3a may be a potential prognostic marker for liver cancer and act as an oncogene by activating JNK and ERK signaling;therefore,eRF3a may be a new target for the treatment of liver cancer.
