TCF4 and hepatocellular carcinoma: In addition, we adopted the CircNet website (http://circnet.mbc.nctu.edu.tw/) to further speculate on the possible regulation mechanisms of circ‐TCF4.85 (Fig. 1B) and then applied the TCGA database to analyze the potential regulatory genes, which demonstrated that ABCF2 was highly expressed in HCC and shared a correlation with HCC prognosis (Fig. 1C,D).
