Plasmacytoma variant translocation 1 stabilized by EIF4A3 promoted malignant biological behaviors of lung adenocarcinoma by generating circular RNA LMNB2.

ABSTRACT: Increasing evidence suggests that plasmacytoma variant translocation 1 (PVT1) plays a vital role in the development of multiple tumors including lung adenocarcinoma (LUAD). Eukaryotic initiation factor 4A-3 (EIF4A3) is considered a key factor in human cancers. However, the role and potential mechanism of PVT1 combined with EIF4A3 in LUAD remain unclear. This study investigated the effects and regulatory mechanisms of PVT1, EIF4A3, and circLMNB2 on the growth, migration, invasion, and epithelial-mesenchymal transition (EMT) of LUAD cells (H1299 and HCC827 cells) The expression level, diagnostic value and prognostic significance of PVT1, EIF4A3, and circLMNB2 were assessed, and enrichment analysis was performed using R package. Rescue experiments and a xenograft model were used to validate t
