To investigate the effects of KPNA2 on lung adenocarcinoma, we downloaded data relating to lung adenocarcinoma from TCGA via UCSC Xena web and compared the expression of KPNA2 in normal and tumor tissues, on the basis of which, we established that KPNA2 is highly expressed in tumor tissues (Fig. 1A). Here, KPNA2 is linked to lung adenocarcinoma.
