LINC00942 and hepatocellular carcinoma: Furthermore, we confirmed that downregulation of LINC00942 (a risk factor) expression increased pyroptosis levels and promoted infiltration of CD3 in HCC, while si-AC009283.1 group (a protective factor) exerted opposite effects <i>in vitro</i>.<h4>Conclusion</h4>This risk signature developed using eight PRlncRNAs exhibits high reliability for predicting the prognosis of HCC patients and assessing their immune status, emphasizing their crucial roles in guiding immunotherapy and crafting precise treatments for the benefit of patients.
