Mitochondrial quality control (MQC) is a central mechanistic hub that maintains mitochondrial homeostasis through coordinated biogenesis, mitophagy, dynamics, proteostasis, and mitochondria-derived vesicles. It is implicated in chemotherapy-related cognitive impairment, where it is described as a key pathogenic framework, and in broader mitochondrial maintenance strategies using mitochondria-targeted hydrogels. MQC is also relevant to multiple chemotherapy classes that converge on its impairment, including alkylating agents, anthracyclines, antimetabolites, microtubule inhibitors, and platinum compounds. Recent literature highlights therapeutic restoration of mitochondrial maintenance in disease models and positions MQC as a targetable axis for intervention. Overall, the concept integrates mitochondrial turnover, quality surveillance, and stress adaptation into one disease-relevant control system.
Chemotherapy-related cognitive impairment
- A 2026 Neoplasia review (PMID:41723889) described MQC as a central hub in chemotherapy-related cognitive impairment pathogenesis.
- The same study linked chemotherapy-induced injury to impairment across MQC components, including biogenesis, mitophagy, dynamics, proteostasis, and mitochondria-derived vesicles (PMID:41723889).
- alkylating agents, anthracyclines, antimetabolites, microtubule inhibitors, and platinum compounds were described as converging on MQC impairment pathways (PMID:41723889).
- The paper emphasized therapeutic interventions aimed at restoring MQC as a strategy to mitigate cognitive toxicity (PMID:41723889).
Mitochondrial therapy and disease models
- A 2026 Biomaterials paper (PMID:41691799) reported that mitochondria-targeted hydrogels restored mitochondrial maintenance processes in disease models.
- This work supports MQC as a modifiable therapeutic axis rather than only a disease marker (PMID:41691799).
- The hydrogel-based approach was framed as part of a new frontier in mitochondrial therapies, with direct relevance to mitochondrial homeostasis (PMID:41691799).
