EIF4A3 Acts on the PI3K-AKT-ERK1/2-P70S6K Pathway through FLOT1 to Influence the Development of Lung Adenocarcinoma.

ABSTRACT: Lung adenocarcinoma (LUAD) is a major lung cancer subtype. In this study, we discovered that the eukaryotic translation initiation factor EIF4A3 expression was significantly higher in LUAD tissues and that this higher expression was closely linked to a poor prognosis for LUAD. In addition, we demonstrated that the knockdown of EIF4A3 significantly inhibited the proliferation, invasion, and migration of LUAD cells in vitro and in vivo. The findings of mass spectrometry analysis revealed that EIF4A3 could interact with Flotillin-1 in LUAD cells and that EIF4A3 could positively regulate the expression of FLOT1 at the protein level. Meanwhile, transcriptome sequencing showed that EIF4A3 could influence the development of LUAD by affecting PI3K-AKT-ERK1/2-P70S6K and PI3K class III-mediated auto
