Abstract
Diabetic kidney disease (DKD) is one of the most frequent complications of diabetes and, if left uncontrolled, can progress to renal failure. In the early stage of DKD, significant pathological changes occur in podocytes, leading to proteinuria. However, the mechanism of pathological changes in podocytes has not been clarified. Existing clinical diagnostic methods tend to overlook these subtle pathophysiological changes in the early stages, leading to missed optimal treatment time. Moreover, existing treatment methods are limited. Emerging evidence strongly suggests that podocyte injury is associated with distinct specific miRNA expression profiles that precede the onset of overt proteinuria and glomerular filtration rate decline. This review explores the role of microRNAs in podocyte damage-related pathways in DKD, such as reactive oxygen species (ROS) production and inflammatory responses. Furthermore, we discuss the potential clinical application of miRNAs as molecular markers and their feasibility as a molecular therapy.
