In this study, co-expression network analysis of differentially expressed ARGs (DEARGs) and differentially expressed lncRNAs (DElncRNAs) will be used to identify for differentially expressed autophagy-related lncRNAs (DEARlncRNAs), to construct a prognostic signature to evaluate the prognosis of HCC patients. The gene discussed is SERPINA2; the disease is hepatocellular carcinoma.
