PBX1-SIRT1 Positive Feedback Loop Attenuates ROS-Mediated HF-MSC Senescence and Apoptosis

This study found that PBX1 overexpression reduces hair follicle-derived mesenchymal stem cell senescence and apoptosis by interacting with SIRT1 and PARP1, highlighting a potential mechanism for addressing aging-related diseases.

This study found that PBX1 overexpression reduces hair follicle-derived mesenchymal stem cell senescence and apoptosis by alleviating ROS-mediated DNA damage, rather than enhancing DNA repair.

This study found that PBX1 enhances the proliferation and reprogramming of hair follicle mesenchymal stem cells by activating the AKT/GSK3β signaling pathway, promoting NANOG expression, and inhibiting apoptosis.

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

This article explores how the integrated stress response and senescence-associated secretory phenotype influence stem cell fate decisions, highlighting their dual roles in both protecting and disrupting stem cell integrity.
