Menstrual endometrial breakdown induced by estradiol and progesterone withdrawal is regularly attributed to vasospasm of spiral arteries causing ischemia and hypoxia. We investigated whether hypoxia actually occurred in an in vivo model of …

Lynch syndrome is an autosomal dominant cancer-susceptibility disorder caused by mutations in DNA mismatch repair genes. Women with Lynch syndrome have an increased lifetime risk for endometrial and ovarian cancers. While there is evidence …

Coupling of focal degradation and renewal of the functional layer of menstrual endometrium is a key event of the female reproductive biology. The precise mechanisms by which the various endometrial cell populations control extracellular mat…

BACKGROUND: Menstruation is associated with a striking increase in matrix metalloproteinase (MMP) activity. However, it is still unknown whether the level of MMP activity correlates with the amount of menstrual bleeding. METHODS: We used h…

Curettage and endometrial ablation aggress the endometrium of menorragic women, thus decreasing the menstrual volume. Curettage only ablates the superficial layer of the endometrium and menorragia reappears in 50% of the cases at one year. …

Various matrix metalloproteinases (MMPs) participate in the menstrual breakdown of the human endometrium. MMP-9/gelatinase B is proposed as a major factor because it degrades many extracellular matrix constituents, including in the vasculat…

Irregular dysfunctional bleeding of the endometrium (ie, metrorrhagia without organic lesion) is common in women, whether treated or not with ovarian hormones. Several matrix metalloproteinases (MMPs) become normally expressed and/or activa…

Recent studies strongly suggest that matrix metalloproteinases (MMPs) play a key role in the initiation of menstrual bleeding in the human endometrium upon the fall of ovarian steroid serum concentrations by inducing the degradation of the …
