Core Tip

Core tip: This manuscript examines the differential expression of long noncoding RNAs in hepatitis B virus-related hepatocellular carcinoma using gene ontology and pathway analyses, and constructing a long noncoding RNA-mRNA network to research the data. Furthermore, RNA immunoprecipitation revealed that the large intergenic noncoding RNA ULK4P2 physically combined with enhancer of zeste homolog 2 (EZH2). EZH2 plays an important role in many cancer types and is critical for cancer cell proliferation, survival, and metastasis, and drug resistance. The combination of ULK4P2 and EZH2 provides a novel avenue for further study of ULK4P2 in hepatitis B virus-related hepatocellular carcinoma.
