To examine the changes in matrix metalloproteinase-2 (MMP-2) and -9 (MMP-9) in the development and progression of endometriosis, real time quantitative polymerase chain reaction, enzyme-linked immunoabsorbent assay and gelatin zymography were employed to determine the mRNA and protein levels and activities of MMP-2 and MMP-9 from the first day to the 21(st) day after the induction in mice with induced endometriosis (experimental group) and sham-operated animals (controls). The results showed that the mRNA and protein levels and activities of the MMP-2 and MMP-9 were significantly increased on the first day after the induction and the level of MMP-2 stayed at a level higher than that in the control group. MMP-9 had two or three peaks during the 21 days, taking place at day 1, 4 and 15. It is concluded that the changes in the MMP-2 and MMP-9 might be involved in pathogenesis of endometriosis.
