title: Matrix remodeling in the ovary: regulation and functional role of the plasminogen activator and matrix metalloproteinase systems.
abstract: In each reproductive cycle, extensive tissue remodeling takes place in the ovary during follicular development, ovulation, formation and regression of corpus luteum (CL) and follicular atresia. Several lines of indirect evidence suggest that these changes are mediated, in part, by proteases belonging to the plasminogen activator (PA) and the matrix metalloproteinase (MMP) systems. These two enzyme systems include both proteinases and associated inhibitors, that are thought to act in concert via a cascade of proteolytic events, the end result of which is the generation of a broad spectrum proteolytic activity, that can mediate physiological tissue remodeling throughout the body. The current review highlights the key features of these two enzyme systems and focuses on their regulation and functional role during the dynamic remodeling processes that takes place in the ovary during each reproductive cycle.
