The expression level of EIF4A1 in tumor tissues was higher than that in normal tissue samples of LUAD, but this was not the case for the expression of EIF4A2 (left panel, Figure 1A), and the expression levels were higher in the advanced stages and advanced lymph node status for EIF4A1 but not EIF4A2 (right two panels, Figure 1A). This evidence concerns the gene EIF4A2 and neoplasm.
