| contents | The Interaction Between Mitophagy Dysregulation and the Diabetic Bladder Microenvironment Shi Li Zongyao Fan Zheng Duan Jun Xue Zhongqing Wei Journal of Diabetes ABSTRACT Diabetic bladder dysfunction (DBD) is a prevalent and multifactorial urological complication of diabetes, with pathogenesis driven by complex interactions between hyperglycemia‐induced oxidative stress, mitochondrial dysfunction, and bladder microenvironment dysregulation. Mitophagy, a selective autophagic process critical for mitochondrial quality control, has been linked to various metabolic diseases, but its precise role and the bidirectional interactions with the diabetic bladder microenvironment remain underexplored. This review outlines a novel, self‐reinforcing feedback loop central to DBD progression. In this cycle, hyperglycemia impairs both the PINK1/Parkin‐mediated mitophagy pathway and ubiquitin‐independent pathways like FUNDC1 under hypoxic conditions, leading to the accumulation of damaged mitochondria. Mitochondrial dysfunction then exacerbates microenvironmental damage through excessive mitochondrial reactive oxygen species (mtROS) production, release of damage‐associated molecular patterns (DAMPs), and activation of the NLRP3 inflammasome, which further drives inflammation, fibrosis, and extracellular matrix (ECM) remodeling. This aggravated microenvironment inhibits mitophagy, thereby accelerating the pathogenic cycle. Beyond elucidating this loop, this review suggests that targeting it offers a promising therapeutic strategy. A breakthrough in DBD treatment may necessitate a combined approach that both restores mitophagy and modulates the microenvironment. Additionally, this study critically reviews several promising, yet underexplored, interventions, including pharmacological mitophagy activation with urolithin A, NACHT, LRR, and PYD domains‐containing protein 3 (NLRP3) inflammasome inhibition via MCC950, and advanced techniques like nanoparticle‐mediated PINK1 mRNA delivery and CRISPR/Cas9‐based Parkin gene editing. Future research should incorporate spatial transcriptomics to resolve cellular heterogeneity, develop targeted nanodelivery systems, and establish mechanism‐driven, highly specific combination therapies to enable precision medicine for DBD. 10.1111/1753-0407.70199 http://creativecommons.org/licenses/by/4.0/ |
