Abstract:Objective To investigate the mechanism of ferroptosis in hepatocellular carcinoma and the prognostic value of long non-coding RNA (lncRNA). Methods Hepatocellular carcinoma transcriptome data were downloaded from TCGA database, ferroptosis differential genes were screened and enriched analyzed; lncRNA associated with ferroptosis was obtained by correlation test; Cox regression analysis was used to construct a prognostic model. According to the risk scoring formula, the risk scores were calculated, and the patients with liver cancer were divided into high, low risk groups, and survival analysis and immune differential analysis were performed. Results Eighty-four ferroptosis differential genes were selected. Enrichment analysis showed correlation with mTOR metabolism, glycolysis, and γ interferon respond, and 17 ferroptosis lncRNAs were included to construct a prognostic model. The prognosis of low-risk group was better than that of high-risk group (P < 0.01); receiver operating characteristic curve showed that the model had good predictive ability. The analysis of immune microenvironment revealed that a variety of immune cells had different infiltration, and 17 immune checkpoints with different expression were identified. Conclusion Both ferroptosis genes and related lncRNAs play important regulatory roles in liver cancer, and the changes of immune microenvironment are also potential targets for liver cancer treatment.
