PCNA and hepatocellular carcinoma: Looking up previous studies, we found that Kong et al. [26] proposed that LUCAT1 promotes the proliferation of oral cancer through PCNA, while Lou et al. [27] also confirmed that LUCAT1 promotes the occurrence of hepatocellular carcinoma by inhibiting ANXA2, which also confirmed that LUCAT1 has a consistent mechanism of action in a number of tumor diseases.
