SUN2 and lung cancer: Individuals with low SUN2 levels were observed to exhibit shorter overall survival (OS) than those with high levels (Fig. 1d).Furthermore, lower SUN2 mRNA expression levels are correlated with a shorter first progression (FP) survival than higher expression levels (Fig. 1e).These results indicate that SUN2 is down-regulated in lung cancer and that its high expression predicts a good outcome in lung cancer.
