NRAV and hepatocellular carcinoma: As a result, nine differentially expressed lncRNAs (AL031985.3, NRAV, OSMR-AS1, AC073611.1, MKLN1-AS, AL137186.2, AL049840.4, MIR4435-2HG, and AL118511.1) were selected as an independent prognostic factor based on the lasso regression in HCC (Figure 4A and Supplementary Table 6).
