OBJECTIVE: To investigate the possible roles of cyclin B1 and cyclin-dependent kanase1 cyclin-dependent kanase1 play in the pathogenesis and development of endometriosis and their association with the ovarian hormones. METHODS: Twenty-nine specimens of ectopic endometrium tissues and 20 specimens of eutopic endometrium tissues were obtained from 29 patients with endometriosis, aged 24 approximately 46. Thirty specimens of endometrium form 30 women without endometriosis were used as controls. The intracellular location of cyclin B1 and Cdc2 was detected by microscopy. Western blotting, RT-PCR, and immunohistochemistry were employed to examine the mRNA expression and protein expression of cyclin B1 and Cdc2. Serum estrogen and progestogen were detected. RESULTS: The expression level of cyclin B1 in the ectopic endometrium from the women with endometriosis was significantly higher than that in the ectopic endometrium tissues from the women with and without endometriosis (both P < 0.05). No significant difference was found between the expression level of cyclin B1 in the ectopic endometrium tissues from the women with and without endometriosis (both P > 0.05). The Cdc2 expression levels were not significantly different among th3 3 groups and the proliferative and secretary stage of endometrium (all P > 0.05). Cyclin B1 expression level was positively correlated with the serum estrogen level, and negatively correlated with the serum progestogen level, and Cdc2 expression was not correlated with the serum sex hormone levels. CONCLUSION: The expression of cyclin B1 in the ectopic endometrium is higher than normal. Cyclin B1 may be involved in the proliferation of endometrium in endometriosis.
