Results indicated that there were no significant difference between the mRNA levels of FUT2 in lung cancer tissues and that in matched tumor-adjacent tissues (n=22) (Figure 1A), however, the mRNA expression levels of FUT2 was markedly increased in lung adenocarcinoma specimens (n=13) (Figure 1B), compared with matched tumor-adjacent tissues. This evidence concerns the gene FUT2 and lung carcinoma.
