SREBF1 and Parkinson disease: A recent study by Junmei Y et al., found that sterol regulatory element-binding protein 1 (SREBP1), as a mTORC1-dependent protein regulated by the SREBP1-transcriptional target stearoyl cofactor desaturase-1 (SCD1), can regulate lipid metabolism and exert a ferroptosis-inhibitory effect (Yi et al., 2020), which may protect against PD.
