A N7-methylguanosine modified circular RNA, circIPP2A2, promotes malignant behaviors in hepatocellular carcinoma by serving as a scaffold in modulating the Hornerin/PI3K/AKT/GSK3β axis.

ABSTRACT: Despite the advancements in treatment strategies, the long-term survival of hepatocellular carcinoma (HCC) is still pessimistic. Therefore, understanding the mechanisms of hepatocellular carcinoma may offer substantial benefits for patients. Our previous research has revealed that Hornerin promoted HCC progression by regulating the AKT signaling pathway. To investigate the upstream regulatory mechanism, the results from RNA Immunoprecipitation and RNA pull-down indicated that the specific region of circIPP2A2 interacted with Hornerin. Additionally, patients with circIPP2A2 upregulation exhibited a poorer survival outcome following surgery compared to the cases with downregulated circIPP2A2. After the structure verification of circIPP2A2, loss-of-function studies using a lentiviral vector r
