Novel Regulatory Role of SIRT3 on Cardiomyocyte Mitochondrial Frataxin and Ferroptosis

Cantrell A, Su H, Zeng H, Chen JX.; FASEB J. 2022 May;36 Suppl 1. doi: 10.1096/fasebj.2022.36.S1.R2008. PMID: 35557151. 

We have demonstrated that cardiomyocyte SIRT3 deficiency causes mitochondrion-specific acetylation and impairment of frataxin and ferroportin potentially via downregulation of HIF-2α. Our results suggest that the SIRT3-ferroptosis pathway may be a novel target for the mitochondrial cardiomyopathy of FRDA.
