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.\nSimilar content being viewed by others\nReferences\nChen QH, Qu JY, Xu YY, et al.
