The final 6 lncRNAs were utilized to construct the risk model for ERS-associated lncRNAs and draw the forest plot(Fig 2C).When we evaluated the expression levels of the above six ERS-associated lncRNAs in HCC tumor and normal samples, we found that the above 6 ERS-associated lncRNAs expressed highly in HCC tumor samples(Fig 2D).The above 6 ERS-associated lncRNAs are MKLN1-AS,LINC01224, AL590705.3,AC008622.2,AC145207.5 and AC026412.3.The expression level and coefficient of the above six lncRNAs were used to calculate the risk score of each HCC patient, use the equation below. The gene discussed is MKLN1; the disease is hepatocellular carcinoma.
