In this study, we investigated the link between AF and senescence markers through the assessment of protein expression in the tissue lysates of human appendages from patients in AF, including paroxysmal (PAF) or permanent AF (PmAF), and in sinus rhythm (SR). The major findings of the study indicated that the progression of AF is strongly related to the human atrial senescence burden as determined by p53 and p16 expression. The stepwise increase of senescence (p53, p16), prothrombotic (TF), and proremodeling (MMP-9) markers observed in the right atrial appendages of patients in SR, PAF, and PmAF points toward multiple interactions in the human atrium that enhance the senescence burden, atrial extracellular matrix remodeling, thrombogenicity, and other putative mediators involved in the progression of AF. MIF Upregulation as a Way to Improve Autologous Mesenchymal Stem Cell Therapy https://www.fightaging.org/archives/2020/01/mif-upregulation-as-a-way-to-improve-autologous-mesenchymal-stem-cell-therapy/ Autologous mesenchymal stem cell therapies involve obtaining cells from patient fat tissue or bone marrow, expanding or purifying the cells in culture, and introducing them back into the patient in order to produce benefits. The precise methodology used matters enormously, and these therapies vary widely in their effects and reliability, even between clinics that are ostensibly performing the same procedure. One issue, among many, is that cells isolated from a...
