NSUN6 and hepatocellular carcinoma: Furthermore, western blotting and qRT‐PCR assays unveiled that NSUN6 expression levels were significantly lower in HCC cell lines (Hep3B, HCCLM3, and SNU449) compared to the human normal hepatic cell line (LX‐2) (Figure 1E,F), supporting the trend of NSUN6 downregulation in HCC and providing a basis for further functional studies.
