Parkin-expressing U2 osteosarcoma (U2OS) ...Defective mitochondrial quality control in response to loss of mitochondrial membrane polarization is implicated in Parkinson's disease by mutations in and . Parkin-expressing U2 osteosarcoma (U2OS) cells were treated with the depolarizing agents oligomycin and antimycin A (OA) and subjected to cryo-focused ion beam milling and in situ cryo-electron tomography. Mitochondria were fragmented and devoid of matrix calcium phosphate crystals. Phagophores were visualized, with bridge-like lipid transporter densities connected to mitophagic phagophores. A subpopulation of ATP synthases relocalized from cristae to the inner boundary membrane. The structure of the dome-shaped prohibitin complex, a dodecamer of PHB1-PHB2 dimers, was determined in situ by subtomogram averaging in untreated and treated cells and found to exist in open and closed conformations, with the closed conformation being enriched by OA treatment. These findings provide a set of native snapshots of the manifold nano-structural consequences of mitochondrial depolarization and provide a baseline for future in situ dissection of Parkin-dependent mitophagy. | |||||||||||||||||||||||||||
