To provide additional evidence to support the HCC growth and progression‐promoting effects of KDM6A, we performed GSEA of TCGA_LIHC dataset and revealed that ‘Liver_cancer_up’ and ‘Metastasis_up’ pathways were significantly enriched in the high KDM6A expression group (Supporting Information Figure S2K). The gene discussed is KDM6A; the disease is hepatocellular carcinoma.
