Moreover, the Sankey diagram showed that the three srlncRNAs were associated with a few coding genes, including PPT1, PTGDS, and ELOVL1. High PPT1 expression is associated with poor prognosis in patients with HCC, and PPT1 inhibition could enhance the sensitivity to sorafenib therapy in HCC (Xu et al., 2022). The gene discussed is PTGDS; the disease is hepatocellular carcinoma.
