Brief description Between 5% and 10% of men over the age of 60 years develop weakening of their main abdominal artery (aorta) leading to slow dilation of the vessel. If this process continues long term the artery can burst resulting in sudden death. At present the only treatment available for this problem is surgery, either open or minimally invasive. Both these forms of treatment are associated with significant complications and unsuitable for some patients. Thus the development of a drug treatment which can slow or halt the weakening and dilation of the aorta would have great patient benefits'. Surprisingly patients with sugar diabetes are less likely to develop this form of artery weakening. This important negative association may form the basis of discovering a new medication to protect arteries from rupture. In this study we investigate the role of a recently discovered protein in protecting the main abdominal artery from weakening in diabetics. This protein is of particular interest for the following reasons: 1. It comes from a group of proteins believed to be important in artery calcium build-up. 2. Artery calcium is common in patients with diabetes who are relatively protected from aortic weakening. 3. It is being used for the treatment of bone weakening, appears to be safe in patients and therefore is a potential therapeutic agent. We believe this work is an important step towards the development of a successful medical treatment for artery weakening.
