In this study, datasets obtained from the International Cancer Genome Consortium (ICGC), Integrative Molecular Database of Hepatocellular Carcinoma (HCCDB), The Cancer Genome Atlas (TCGA), and Gene Expression Omnibus (GEO) databases were utilized for comprehensive analysis of AUNIP expression in different tumor types (HCC and LUAD), including the association of AUNIP expression with prognosis. The gene discussed is AUNIP; the disease is hepatocellular carcinoma.
