Objective: This study was performed to investigate the expressions of endometriosis related genes in shed endometrial tissues from menstrual blood of patients with or without endometriosis.
Methods: The shed endometrial tissues were collected on 2nd or 3rd day of menstrual cycle with Wallace catheter in patients with endometriosis (n=16) and without endometriosis (n=26). The mRNA expressions of twelve kinds of endometriosis related genes were compared between two groups using semi-quantitative RT-PCR.
Results: The collected shed endometrium was confirmed by histological observation. Expressions of telomerase, c-kit and aromatase mRNA were not detected by RT-PCR in shed endometrial tissues. The mRNA expressions of apoptosis related genes (fas, fas ligand, bcl-2, bax), stem cell factor, estrogen receptor-α/α, endometriosis protein-I and secretory leukocyte protease inhibitor gene were similar between shed endometrial tissues with endometriosis and without endometriosis.
Conclusion: We could not find the difference of mRNA expressions of tested endometriosis related genes between shed endometrial tissues with or without endometriosis by semi-quantitative RT-PCR analysis. It may be related to the dynamical changes of gene expressions in the endometrium with menstrual cycle.
