Matrix metalloproteinases-2, -7 and tissue metalloproteinase inhibitor-1 expression in human endometrium
This study found that estradiol influenced MMP-2 expression in human endometrium differently during proliferative, secretory, and menstrual phases, while MMP-7 and TIMP-1 expression showed no relationship with hormone levels or cycle phase.

This study evaluated whether serum estradiol and progesterone levels are associated with endometrial expression of matrix metalloproteinases MMP-2 and MMP-7 and the tissue inhibitor TIMP-1 across menstrual cycle phases. Using immunohistochemistry on 52 endometrial biopsies from proliferative phase, secretory phase, and menstruation, hormone concentrations were measured at biopsy time and analyzed with linear regression. Increased serum estradiol was associated with higher MMP-2 expression in the proliferative phase, but MMP-2 expression decreased in the secretory phase and during menstruation; no significant association was observed between progesterone and MMP-2, and MMP-7 and TIMP-1 showed no differences by hormone levels or cycle phase. This paper is directly about endometriosis—reviewing and ranking biomarkers and mechanisms (MMP/TIMP) in cycling endometrium that have been linked in the literature to endometriosis pathology.
