Abstract
INTRODUCTION: Hepatocellular carcinoma (HCC) is one of the most lethal malignancies in the world. Previous studies indicated that the expression of the KDM1 genes (KDM1s), members of the amine oxidase superfamily, has prognostic value for breast and prostate cancer and malignant neuroblastoma. This study aimed to investigate the expression of KDM1s, their prognostic value, and their correlation with immune infiltration in patients with HCC. METHODS: Multiomics analyses were utilized to analyze differential expression, prognostic value, genetic alteration, and immune cell infiltration of KDM1s in patients with HCC. RESULTS: The high expression of KDM1A indicated poor overall survival (OS) and disease-free survival, whereas the high expression of KDM1B was significantly associated with poor OS. The genetic alterations and biological interaction network of KDM1s may provide detailed information for the dysregulated function of KDM1s in patients with HCC. KDM1-related signaling pathways and miRNA targets were explored and may provide value as therapeutic targets or tumor progression markers. The increased mRNA expression of KDM1s was significantly correlated with the infiltration of diverse immune cells in HCC. CONCLUSIONS: This data-driven study indicates that KDM1s are promising prognostic biomarkers for survival and have the potential to become novel molecular targets in HCC treatments.
