EIF5A2 and non-small cell lung carcinoma: RT-qPCR measurement of MIR9 and EIF5A2 mRNA expression showed that the A549 cells had the highest miR-9 expression but the lowest eIF5A2 expression among the NSCLC cell lines (Figures 3(b) and 3(c)), indicating that miR-9 correlates negatively with eIF5A2 expression.
