Key result
Aging in mice is linked to increased VWF expression and platelet aggregation modulated by cell senescence.
Why the study?
Aging is associated with increased circulating levels of von Willebrand factor, which presents a risk factor for thrombus formation.
Aging induces an organ-specific increase in VWF expression and platelet aggregate formation, potentially modulated by endothelial cell senescence and the p53 transcription factor.
No takes yet. Share an insight, caveat, or question.
May link endothelial senescence to organ-specific thrombosis risk in aging; leaves open human translation and p53 targeting.
Alavi et al. (2023) studied Aging. Aging vs. Young mice / standard culture time was evaluated on Circulating plasma, cellular protein, and mRNA levels of VWF, and vascular pattern of VWF expression. Aging in mice is associated with an organ-specific increase in VWF expression (brains, lungs, livers) and increased platelet aggregate formation, potentially modulated by cell senescence and p53.
