Accumulating evidence indicates that cellular premature senescence of the glomerulus, including endothelial cells, mesangial cells, and podocytes leads to diabetic nephropathy (DN), and DN is regarded as a clinical model of premature senescence. However, the role of cellular senescence-associated genes in the glomerulus in DN progression remains unclear. Therefore, this work aims to identify and validate potential cellular aging-related genes in the glomerulus in DN to provide novel clues for DN treatment based on anti-aging. The microarray GSE96804 dataset, including 41 diabetic glomeruli and 20 control glomeruli, is retrieved from the Gene Expression Omnibus (GEO) database and cellular senescence-related genes (CSRGs) are obtained from the GeneCards database and literature reports. Subsequently, PPI, GO, and KEGG enrichment are analyzed by screening the intersection between differentially expressed genes (DEGs) and CSRGs. scRNA-seq dataset GSE127235 is used to verify core genes expression in glomerulocytes of mice. Finally, db/db mice are utilized to validate the hub gene expression in the glomeruli, and high glucose-induced mesangial cells are used to confirm key gene expression. This study reveals that FOS and ZFP36 may play an anti-aging role in DN to ameliorate cell intracellular premature aging in mesangial cells of glomeruli.

Background: Diabetic nephropathy (DN), the predominant driver of end-stage renal disease globally, remains therapeutic option in clinical practice. Bruceine A (BA) demonstrates nephroprotective properties, however, its clinical translation has been hindered by dose-limiting toxicities. We synthesized BA derivatives P1 to overcome the limitation, presenting a novel therapeutic candidate for DN management.

Spinal cord injury (SCI) represents one of the recognized difficulties, and its pathological mechanisms remain unclear. Aberrant regulation of the RNA-binding protein (RBP) and selective splicing are associated with SCI. Nonetheless, the mechanisms of RBP regulation and abnormal selective splicing events associated with SCI are unexplored.

Although essential for oxygen transport and DNA synthesis, excess iron is toxic and can damage organs such as the kidneys. Research has shown that iron overload induces kidney injury, and aging contributes to kidney dysfunction through functional and structural changes. The interaction between iron overload and aging remains poorly understood.

Diabetic kidney disease (DKD) is a serious diabetic complication, the morbidity and mortality of which has rapidly increased worldwide. As known, the pathogenesis of DKD is complex and includes mesangial cell (MC) proliferation and hypertrophy, mesangial expansion, glomerular basement membrane thickening, podocyte detachment, and tubulointerstitial damage. Thus, the role of MCs cannot be underestimated, as their exclusive positioning and diverse physiological functions are crucial for preserving the glomerular filtration membrane's composition and functionality.
