Study Title: Mitochondria in oxidative stress, inflammation and aging: from mechanisms to therapeutic advances
Citation: Xu et al., 2025 · Signal Transduction and Targeted Therapy
What the Study Found: This review explains how mitochondrial dysfunction can connect oxidative stress, inflammation, and aging. The authors describe several mitochondrial mechanisms involved in this process, including excess reactive oxygen species, imbalance between oxidation and antioxidant defenses, mitochondrial DNA damage, altered mitochondrial dynamics, and impaired mitophagy. The review also discusses mitochondria-targeted therapeutic strategies, including approaches aimed at improving mitochondrial quality control, reducing oxidative stress, and supporting mitochondrial function, while noting that clinical translation still has important limitations.
What this means in real life: Mitochondria are not only energy producers. They also help cells manage stress, repair damage, regulate redox balance, and respond to inflammatory signals. When mitochondrial function declines, cells may become less able to handle everyday biological stress, which helps explain why mitochondrial health is so closely tied to aging, resilience, and long-term cellular function. This does not mean mitochondria explain aging by themselves, but they are an important part of the larger biology.
Clinical Relevance: Mechanistic review, mitochondrial biology, oxidative stress, inflammation, and aging; not direct clinical trial evidence.
