Aneurysm-osteoarthritis syndrome characterized by unpredictable aortic aneurysm formation, is caused by SMAD3 mutations. SMAD3 is part of the SMAD2/3/4 transcription factor, essential for TGF-β-activated transcription. Although TGF-β-related gene mutations result in aneurysms, the underlying mechanism is unknown. Here, we examined aneurysm formation and progression in Smad3−/− animals.Smad3−/− animals...
DNA damage and ageing share expression changes involving alterations in many aspects of metabolism, suppression of growth and upregulation of defence and genome maintenance systems. “Omics” technologies have permitted large-scale parallel measurements covering global cellular constituents and aided the identification of specific response pathways that change during ageing and after DNA damage. We...
