Chen et al. [121] reported that the sensitivity of the HCC cell lines HuH7, Hep3B, SNU-387 and SNU-449 to sorafenib treatment was inversely correlated with the expression levels of lncRNA-POIR (human periodontal ligament stem cell osteogenesis impairment-related lncRNA). Here, LNCPOIR is linked to hepatocellular carcinoma.
