The expression of interstitial collagenase in human endometrium is controlled by progesterone and by oestradiol and is related to menstruation.
Human endometrial tissue, sampled at different periods of the reproductive cycle, expressed interstitial collagenase mRNA, protein and activity only just before and during the menstrual period. This clear-cut correlation and the inhibition of collagenase expression by progesterone and oestradiol in tissue culture point to a pivotal role of this proteinase in the mechanism of menstrual tissue breakdown and bleeding.
