ELF3 and breast cancer: When compared with adjacent non-malignant lung tissue, ELF3 was significantly overexpressed in LUAD in the BC Cancer Agency (BCCA) (n = 83 pairs, Wilcoxon sign-rank p = 1.64E-21) and TCGA data sets (n = 571, Mann–Whitney U test p = 1.54E-07) (Fig. 1c), but not differentially expressed in LUSC (Supplementary Fig. 1b).
