Cellular senescence affects many physiological and pathological processes and is characterized by durable cell cycle arrest, an inflammatory secretory phenotype and metabolic reprogramming. Here, by using dynamic transcriptome and metabolome profiling in human fibroblasts with different subtypes ...
Background Androgenetic alopecia (AGA), the most prevalent form of hair loss, is driven by the dysfunction of dermal papilla cells (DPCs). Emerging evidence implicates DPC senescence in the pathogenesis of AGA; however, the underlying molecular mechanisms remain incompletely elucidated.
<...Chronic kidney disease (CKD) is a major health issue, with podocyte injury with senescence playing a central role in glomerulosclerosis. This study investigates the link between glycolysis-derived serine metabolism and podocyte injury with senescence, focusing on the role of phosphoglycerate kina...
SIRT5 deficiency caused widespread protein hypersuccinylation in cardiac tissue. Succinylation proteomic analysis revealed HADHB as the key SIRT5 target, with lysine 292 (K292) being the dominant succinylation site. Functional studies demonstrated that K292 succinylation impairs HADHB-mediated fa...
BACKGROUND: Periodontal ligament mesenchymal stem cells (PDLSCs) are a promising cell resource for cell-based regenerative medicine in dentistry. PDLSCs inevitably acquire a senescent phenotype after prolonged in vitro expansion, and the key regulators of cells during replicative...
