Integrative Insights Into Mitochondrial Dysfunction and Organelle Crosstalk in Diabetic Kidney Disease
How Mitochondrial Problems and Cell Structure Interactions Are Linked to Kidney Disease in Diabetes

Abstract
Mitochondrial dysfunction is a major driver of diabetic kidney disease (DKD), contributing to glomerular and tubular injury.
- Early and sustained mitochondrial dysfunction is associated with metabolic changes, oxidative stress, and inflammation in DKD.
- Four interrelated mitochondrial factors—metabolic reprogramming, altered fission-fusion dynamics, defective mitophagy, and mtDNA release—are linked to DKD progression.
- Mitochondria-endoplasmic reticulum contacts (MAMs) play a critical role in integrating redox signaling and calcium balance.
- Preclinical studies suggest that enhancing mitochondrial function may reduce kidney injury.
- Clinically approved agents, including metformin and SGLT2 inhibitors, show renoprotective effects through mitochondrial pathways.
