Coordinate expression of matrix metalloproteinase family members in the uterus of normal, matrilysin-deficient, and stromelysin-1-deficient mice.

The expression patterns of matrix metalloproteinase (MMP) family members during the murine estrous cycle and postpartum uterine involution were analyzed, and the consequence of removing specific MMPs during uterine functions was determined using mice deficient in either matrilysin (MAT) or stromelysin-1 (STR-1). In wild-type animals, MAT, STR-1, STR-2, STR-3, and gelatinase A were consistently expressed during the most active phases of the estrous cycle, estrus and proestrus. The messenger RNA for these MMPs as well as collagenase-3 and the tissue inhibitors of metalloproteinases were also expressed during uterine involution, as determined by Northern analysis and in situ hybridization. Notably, MAT, STR-2, and collagenase-3 messenger RNA levels were elevated at early times of involution and rapidly decreased with time, whereas the transcripts for other MMPs remained elevated throughout the involution process. Involution proceeded normally in mice lacking MAT or STR-1; however, the expression of STR-1 and STR-2 was dramatically up-regulated in MAT nullizygous mice, and the expression of MAT and STR-2 was moderately up-regulated in STR-1-deficient animals. We conclude that the concerted action of several MMPs is likely to play an important role in the remodeling of the postpartum uterus, and that mechanisms that compensate for the loss of a specific MMP during this process appear to exist.[1]
