Abstract

A combination of E and progestogens significantly increased matrix metalloproteinase (MMP)-2 in both T47D cells (E(2)-medroxyprogesteroneacetate [MPA] and E(2)-P) and MCF-7 cells (E(2)-MPA, E(2)-P, and equilin-MPA). All combinations resulted in higher MMP-9 levels in MCF-7 cells, but higher MMP-9 levels resulted only with equilin-norethinderone in T47D cells.

Subjects
Enzyme Activation, Female, Humans, Pilot Projects, Postoperative Period, Endometriosis blood, Endometriosis surgery, Matrix Metalloproteinase 9 blood
Abstract

Matrix metalloproteinases (MMPs) may have a role in the pathogenesis of endometrioma. The level of MMP was lower compared to the level taken after resection of endometrioma.

3. Comparisons of matrix metalloproteinase 1, 2, and 9 activity in periovulatory follicular fluid from natural and stimulated menstrual cycles.

Author

Subjects
Adult, Clomiphene therapeutic use, Female, Fertility Agents, Female therapeutic use, Follicle Stimulating Hormone therapeutic use, Gonadotropin-Releasing Hormone agonists, Humans, Matrix Metalloproteinase 1 metabolism, Matrix Metalloproteinase 2 metabolism, Matrix Metalloproteinase 9 metabolism, Progesterone metabolism, Follicular Fluid metabolism, Matrix Metalloproteinases metabolism, Menstrual Cycle, Ovarian Follicle metabolism, Ovulation Induction
Abstract

We studied the activity levels of matrix metalloproteinase 1, 2, and 9 in periovulatory fluids from naturally occurring menstrual cycles versus those from samples taken from menstrual cycles stimulated with clomiphene citrate or recombinant stimulating hormone. No statistically significant differences were found.

4. Plasma matrix metalloproteinase activity during the menstrual cycle of healthy ovulatory patients who underwent tubal ligation.

Abstract

The plasma profiles of active metalloproteinase (MMP)-1, MMP-2, and MMP-9 levels during the normal menstrual cycle in ovulating, healthy and tubal ligated patients were studied. The active MMP-1 and MMP-9 plasma levels were found to vary in the menstrual cycle. Active MMP-2 levels, however, are constant during the menstrual cycle.
