To determine whether the expression of hnRNPK was associated with LUAD resistance to EGFR‐TKIs, we further analysed public datasets from TCGA and GEO and found that the expression levels of hnRNPK were significantly higher in gefitinib‐resistant lung cancer cell lines compared with their parental cells and strongly associated with poor overall survival (Figure S7D), indicating that hnRNPK was involved in LUAD resistance to EGFR‐TKIs. This evidence concerns the gene EGFR and lung cancer.
