Expression of fibrinolytic genes in tissues from human atherosclerotic aneurysms and from obese mice

Abstract

The disturbances in the balance of pro- and antifibrinolytic activity, as observed in AAA and obesity, respectively, have considerable potential for influencing both intra- and extravascular fibrinolytic events and may be causally related to the development of vascular disease. For example, the wall of the aortic atherosclerotic aneurysm seems to host an uneven distribution and imbalanced expression of the various components of the fibrinolytic system. The sites of increased proteolytic activity may contribute to localized neovascularization and promote the rapid breakdown of ECM components, which result in mural weakening and eventual rupture of untreated aortic aneurysms. On the other hand, the disturbance of the normal hemostatic balance observed in obesity appears to result from the elevated expression of PAI-1 by the adipose tissue. Our data strongly suggest that the adipocyte is one of the primary cells in the adipose tissue capable of expressing PAI-1 both in obesity, and in response to cytokines and hormones like TNF-alpha and insulin. Since both TNF-alpha and insulin are known to increase in obesity, the elevated levels of PAI-1 observed in the plasma of obese individuals may result from TNF-alpha and/or insulin induct...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
