Unpaired data analyses also showed that the mRNA expression levels of LIMK1 in lung adenocarcinoma tissues (n = 535) were significantly higher than those in adjacent normal tissues (n = 59) (Figure 2B, 5.314 ± 0.847 vs. 4.324 ± 0.437, Mann-Whitney U-test, P < 0.001). Here, LIMK1 is linked to lung adenocarcinoma.
