Advancements in Understanding the Role and Mechanisms of Mitochondria in Diabetes: A Comprehensive Review.

Abstract

Diabetes mellitus is a global health crisis with a rising prevalence attributed to complex interactions of genetic, lifestyle, and environmental factors. This comprehensive review delves into the pivotal role of mitochondrial dysfunction in the onset and progression of diabetes. It outlines how defects in mitochondrial oxidative phosphorylation, increased free radical production, and mitochondrial DNA damage contribute to insulin resistance, β-cell apoptosis, and systemic metabolic dysfunctions. The review highlights the critical roles of mitochondria in energy metabolism, oxidative balance, and the interplay of genetic and environmental factors in diabetes. It also emphasizes the association of impaired mitochondrial function with various diabetes-related complications and organ-specific diseases, underscoring the urgent need for innovative therapeutic strategies. Potential interventions discussed include pharmacological agents promoting mitochondrial biogenesis and enhancing mitochondrial dynamics, alongside dietary and lifestyle modifications that support mitochondrial function and overall metabolic health. The review calls for intensified research into mitochondrial mechanisms and their therapeutic targets, advocating for comprehensive clinical trials and support from medical and governmental institutions to advance diabetes management strategies centered on mitochondrial health.
