MMP9 and aortic aneurysm: The recent finding of Creb enhancing inflammation in a model of atherosclerosis (Kotla et al., 2013), coupled to the contribution of Mmp9 in atherosclerotic lesion rupture (Gough et al., 2006) and development of aortic aneurysm (Duellman et al., 2012; Longo et al., 2002), suggest that Creb-like proteins might have a function in Mmp9-related vascular disease.
