To investigate the correlation between expression of p-Mnk1 and p-eIF4E and clinicopathological features of NSCLC, expression of p-Mnk1 and p-eIF4E was detected by immunohistochemistry (IHC) in the NSCLC tissue microarray (TMA) (Figure 1A) which contained 353 cases of NSCLC and 53 cases of non-cancerous lung tissues (Non-CLT). Here, EIF4E is linked to non-small cell lung carcinoma.
