Maltol as a Novel Agent Protecting SH-SY5Y Cells Against Hemin-induced Ferroptosis

Ferroptosis triggered by hemin is regarded as a primary factor accounting for neuronal death secondary to intracerebral hemorrhage.Thus,compounds with inhibitory effect on hemin-induced ferroptosis might be potential medicines to prevent neuronal death caused by intracerebral hemorrhage.Herein,we investigate whether maltol could alleviate hemin-induced SH-SY5Y cell ferroptosis and its potential mechanisms.It is found that maltol effectively prevents hemin-induced SH-SY5Y cell ferroptosis via three pathways.The first one is inhibiting intracellular iron increase via preventing upregulation of transferrin receptor,the second one is alleviating lipid peroxidation via attenuating H_(2)O_(2) generation by NOX4 and promoting H_(2)O_(2) clearance by catalase,and the third one is to reduce peroxidized lipids via maintaining GPX4/GSH pathway.Therefore,maltol is a novel agent preventing hemin-induced SH-SY5Y cell ferroptosis.
