On the other hand, KCNJ14 was significantly downregulated in seven tumours, such as BRCA (p = 1.4 × 10−7), lung adenocarcinoma (LUAD, p = 2.7 × 10−4), prostate adenocarcinoma (PRAD, p = 2.0 × 10−12), skin cutaneous melanoma (SKCM, p = 1.0 × 10−38), thyroid carcinoma (THCA, p = 4.7 × 10−86), ovarian serous cystadenocarcinoma (OV, p = 1.0× 10−3), and testicular germ cell tumours (TGCT, p = 2.2 × 10−42). Here, KCNJ14 is linked to neoplasm.
