Abstract excerpt
BACKGROUND: Mitochondrial DNA (mtDNA) diseases are heterogeneous and lack effective treatments. Their severity correlates with mutant mtDNA load. Mitophagy degrades dysfunctional mitochondria, contributing to a healthy mitochondrial pool. USP30, a mitochondrial deubiquitinase, limits mitophagy by removing the ubiquitin tagging mitochondria for degradation. We investigated whether inhibiting USP30 could enhance...
