The RNA-binding protein ELAVL1 regulates ferroptosis by inducing ferritinophagy activation in HSCs. Ferroptosis-inducing compounds increase ELAVL1 expression through the inhibition of the ubiquitin-proteasome pathway. Increased ELAVL1 can bind to the AREs of the BECN1 mRNA 3ʹ-UTR, trigger autophagy activation, promote autophagic ferritin degradation, and in turn, lead to HSC ferroptosis.
