HBx was found to induce DNMT upregulation, leading to DNA methylation of the genes involved in the Ras pathway and angiogenesis [106], and to interact directly with DNMT3A to recruit it to the promoters of IL-4R, a gene encoding a cytokine receptor involved in apoptosis, and MT1F, a potential tumor-suppressor gene, leading to their methylation-silencing [107]. The gene discussed is DNMT3A; the disease is neoplasm.
