POLR2J4 and hepatocellular carcinoma: For instance, using the gene expression file GSE76427, Gu et al. (2019) discovered that six long non-coding RNA (MSC-AS1, POLR2J4, EIF3J-AS1, SERHL, RMST and PVT1) were associated with a poor prognosis of HCC and constructed a nomogram including the six-lncRNA signature, TNM stage and ECOG to predict RFS for patients with small HCC.
