DARS2 overexpression in lung adenocarcinoma and its correlation with clinicopathological features. A–C The volcano map shows the limma analysis results of TCGA LUAD, GSE19188 and GSE30219 datasets. D There was a significant increase in DARS2 expression in the tumor group compared to the normal group, in TCGA LUAD, GSE19188 and GSE30219 datasets. E The expression difference of DARS2 in different pathological stages in TCGA LAUD dataset. F Kaplan–Meier curve shows the overall survival of TCGA LUAD datasets. ns means not significant; **p < 0.01, ***p < 0.001
