BACH1 and hepatitis A virus infection: BACH1 also plays a significant role in HBV‐induced hepatitis.[305, 319] The control of HBV infection relies heavily on CD8+ T cells.[320] The high activity of BACH1 is observed in HBV‐specific effector and memory T cells.[305] Inhibition of CircBACH1, a circular RNA derived from the BACH1 gene, showed suppressive impacts on HBV replication and hepatocellular carcinoma progression by influencing the miR‐200a‐3p/MAP3K2 axis.[319, 321] Thus, even with conflicting findings, BACH1 is crucial in HCV and HBV infections and remains promising for antiviral treatment.
