Knockdown of EIF3G inhibits the intracellular protein translation of H1299 cells


ABSTRACT: eIF3 is the largest translation initiation factor in mammalian cells, consisting of 13 subunits. This translation initiation factor is involved in multiple processes of protein translation in cells, including translation initiation, termination, and ribosome recycling. Several studies have reported that multiple subunits of eIF3 exhibit abnormal expression in tumor cells and play an important role in the occurrence and development of tumors. In this study, it was found that changes in the expression level of EIF3G significantly affected the growth of non-small cell lung cancer. Knockdown of EIF3G inhibited the intracellular protein translation process of non-small cell lung cancer cells H1299. Through the study of translatome, it was found that knockdown of EIF3G significantly affected the cell cycle processes in H1299 cells. In vitro cell experiments also showed that changes in the expression level of EIF3G influences the cell cycle distribution of H1299 cells. This study is the first to explore the impact of knockdown of EIF3G on the translatome of H1299 cells.
