Our study has analyzed whether inappropriate gonadotropin secretion affects the morphological changes due to the activation of intrauterine MMP.
Methods A total of each 6 mice were injected with PMSG, Progesterone, and Androgen in 5 IU of intraperitoneal injection every 2 days after estrus synchronization, and morphological and MMPs expression patterns were compared after inducing hormone secretion. Also, cell survival and death related genes were compared and analyzed. The endometrium was highly developed in the PMSG, and the androgen was not developed at all. In particular, the diameter of the uterus of the Androgen group was also very narrow. MMPs activity assay in the case of PMSG was confirmed that showed low activity, whereas, progesterone and androgen In showed high activity and, in particular, very high activity of MMPs in the case of androgen in glandular cell. The expression of VEGF in the tissues of each group was different from that of MMPs. In the PMSG group, the activity of VEGF was increased in both the Myo-metrium and the endo-metrium, whereas the progesterone group showed low overall expression in the endo-metrium. Therefore, the present study showed that the activities of the endo-metrial cells and the restructuring of the endometrial cells differed according to the type of the abnormal secretory hormone. In particular, the secretion of androgen increased the activity of MMPs throughout the uterus, The endo-metrial epithelial cells are affected by the progesterone group. In conclusion, this study suggests that inappropriate gonadotropin secretion increases the functional changes of the uterus and this reconstruction may be caused by increased activity of MMPs
