Figure 4 Hepatitis B virus regulates microRNAs biogenesis. Hepatitis B virus (HBV) regulates the biogenesis of miRNA by affecting the miRNA-related Rnases. HBx protein downregulates Drosha expression through reduction of the transcriptional activity of Drosha promoter and upregulates the expression of transcription factor YY1 to suppress DGCR8 expression by repressing DGCR8 promoter activity. Single nucleotide polymorphisms (SNPs) located on 3’UTR of Dicer and RAN genes affect the biogenesis of miRNA in HBV-related diseases. DGCR8: DiGeorge syndrome critical region gene 8.
