KDM4B and neoplasm: After including the normal tissue of the Genotype‐Tissue Expression (GTEx) dataset as controls, we further evaluated the expression difference of KDM4B between the normal tissues and tumor tissues of several more cancer types, where KDM4B expression was significantly higher in LGG tumors but lower in ovarian serous cystadenocarcinoma (OV), uterine carcinosarcoma (UCS), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), and testicular germ cell tumor (TGCT) tissues, compared to their corresponding normal tissues (Figure 6B, p < 0.05).
