The regulation of CHAC1/BOTCH involves additional molecular players: during intracerebral hemorrhage, inhibition of CHAC1/BOTCH by the androgen receptor (AR) and Jumonji-domain containing protein-3 (JMJD3) led to elevated NOTCH1 levels and exacerbated neuroinflammation (Chen et al., 2021). Here, AR is linked to intracerebral hemorrhage.
