METTL14 Induced N6-Methyladenosine Modification of FOXP4 mRNA in HBV-HCC.
Chronic hepatitis B virus infections are a significant cause of liver cirrhosis and cancer. Our research reveals that HBV infection leads to a marked increase in m6A modification of Foxp4 mRNA, resulting in enhanced stability of the mRNA and a subsequent increase in Foxp4 mRNA levels. Analysis of biopsy samples from chronic HBV patients demonstrated consistent upregulation of m6A-modified Foxp4 mRNA levels alongside increased Foxp4 mRNA levels. Functionally, Foxp4 was found to promote proliferation, migration, and invasion of hepatocellular carcinoma (HCC) cells in laboratory settings. Additionally, HBV gene expression was shown to activate the PI3K/AKT pathway by modulating Foxp4 mRNA stability in HCC cells. This study provides valuable insights into the underlying mechanisms of HBV infection and its potential implications for cancer development.
