3. Figure 2
Proposed model for ERα-related suppression of HBV replication. ERα is translocated into the nucleus and binds to HNF4α through the ERα hinge region, reducing HNF4α DNA-binding capacity to, and activity of, HBV enhancer I. This interaction impairs HBV transcription, leading to reduction in HBV titers.
