Sample text

Three major families of factors are secreted by senescent cells, including soluble signaling factors (interleukins, chemokines, and growth factors), insoluble proteins/ECM components, and secreted proteases. The proteases include matrix metalloproteinases (MMPs), serine proteases, and regulators of plasminogen activation, including uPA and uPAR. Upregulated expression of the system has also been well documented in vascular remodeling and atherosclerosis (Binder et al. 2007). The main stream of research on the role of uPA/uPAR in vascular pathology is focused, however, on the expression and function of this system in adhesion/migration of inflammatory cells.

4 uPA/uPAR System Therapeutic Perspectives A wide variety of functions exerted by the urokinase system in the vascular wall make it an attractive therapeutic target. Cleaved forms of uPAR, in particular suPAR, are found in biological fluids like plasma and urine. suPAR has recently been proven to serve as a marker and mediator of multiple inflammatory, cardiovascular, and kidney diseases. These findings explain the boosting interest in research and development of therapeutic approaches for targeting the uPA/uPAR system.

In Doxinduced VSMC senescence, uPAR is essential for stress-induced activation of proteasomal activity and promotes degradation of TRF-2. Overall, the uPA/uPAR system seems to promote VSMC differentiation to the synthetic phenotype and plays deleterious roles in the progression of vascular diseases. uPA has also been shown to promote oxidative stress in VSMCs and macrophages. Fuhrman and colleagues have shown that uPA activates the NADPH oxidase complex in macrophages, resulting in ROS production (Fuhrman et al.
