Abstract: Objective  Transcriptome sequencing and bioinformatics analysis were used to explore the transcriptional characteristics and survival analysis of non-cirrhotic hepatitis B viral(HBV)-related hepatocellular carcinoma (HCC). Methods  The differentially expressed genes in non-cirrhotic HBV-related HCC were obtained by transcriptome sequencing. The biological functional processes and signaling pathways involved in the differentially expressed genes were obtained by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The key genes were obtained by gene-gene function interaction network analysis, and the key genes were analyzed for survival prognosis using the cancer genome atlas (TCGA) database’s HCC cohort. Results  A total of 3 672 up-regulated differential genes and 2 715 down-regulated differential genes were identified. The GO functional enrichment analysis mainly involved cell differentiation, DNA replication, DNA repair, inflammation response, immune response, cell adhesion, etc, while the KEGG pathway enrichment mainly included cell cycle, oxidative phosphorylation, p53 signaling pathway,tumor necrosis factor(TNF) signaling pathway, and nuclear factor kappa-B(NF-κB) signaling pathway. Among them, high expression of mitogen-activated protein kinase 3(MAPK3), ras-related C3 cotulinum toxin substrate 1(RAC1),phospholipase C beta 1(PLCβ1), catenin beta 1(CTNNβ1), non-metastatic cells 1(NME1), and non-metastatic cells 6(NME6) was associated with poor prognosis in HCC patients (P<0.05), while low expression of FYN, cytochrome P450 2C8(CYP2C8), and cytochrome P450 2C9(CYP2C9) was associated with poor prognosis in HCC patients (P<0.05). Conclusions  Non-cirrhotic HBV-related HCC involves multiple biological processes and alterations in signaling pathways, and the key genes related to the survival and prognosis of HCC patients provide new clues for understanding the mechanism of HBV-related HCC in non-cirrhosis patients.
