Survivin and Bcl-2 expression in eutopic endometrium with and without endometriosis / 대한산부인과학회지

ABSTRACT

OBJECTIVE: To examine expression of survivin and Bcl-2 in eutopic endometrium with endometriosis and without endometriosis by immunohistochemical stain. METHODS: Expression of survivin and Bcl-2 was immunohistochemically investigated in eutopic endometrium with endometriosis (n=30, study group I; laparoscopy-proved endometriosis, study group II; adenomyosis) or without endometriosis (n=34, control group). The score of immunohistochemical staining was evaluated semi-quantitative method modified by Sinicrope and Lu. Statistical analyses was carried out using one-way ANOVA with Turkey test. RESULTS: Survivin expression was significantly higher in nucleus of glandular epithelium of eutopic endometrium with endomtriosis compared to that without endometriosis (p<0.05). Increased expression of Bcl-2 was found in glandular epithelium of eutopic endometrium with endometriosis than without endometriosis, but there was no significantly difference. CONCLUSION: Our findings suggest that increased survivin expression may contribute to survival of endometriosis. Moreover, survivin could play an important role in pathogenesis of endometriosis.
