Expression of integrin β3 and osteopontin in endometrium of patients with adenomyosis

Objective To investigate the expression of integrin β3 and osteopontin(OPN) in eutopic and ectopic endometrium of adenomyosis. Methods From January 2007 to July 2008, the endometrium specimens were collected from 43 patients with adenomyosis undergoing hysterectomy in Peking University First Hospital. Eutopic endometrium were 11 in proliferative phase and 32 in secretory phase (18 cases in mid-secretory phase) were collected. Ectopic endometriums were also collected. In the mean time, it was chosen 41 cases with pure subserous uterine myoma or cervical intraepithelial neoplasia (CIN) Ⅱ-Ⅲ treated by hysterectomy as controls including 12 endometrium in proliferative phase and 29 endometrium in secretory phase (19 cases in mid-secretory phase). The expression of Integrin β3 subunit and OPN in the endometrium were assessed by immunohistochemical staining and quantitative real-time polymerase chain reaction. Results (1)Immunohistochemical staining showed that positive staining of integrin β3 and OPN were present predominantly in eutopic and ectopic endometrial glandular epithelium. There was significant different protein expression of integrin β3 and OPN, which were 1.6±0.8 and 1.7±0.7 in eutopic endometrium,1.7±0.7 and 1.8±0.9 in ectopic endometrium,2.1±0.9 and 2.0±0.9 in control endometrium (P<0.05). The protein expression of integrin β3 and OPN in eutopic endometrium of adenomyosis in the proliferative phase(0.8±0.4 and 0.7±0.3) were remarkably lower than those of the secretory phase(1.8±0.8 and 1.9±0.8,P<0.01). The protein expression of integrin β3 and OPN in the endometrium of controls in the proliferative phase(1.0±0.4 and 1.0±0.4) were significantly lower than those of the secretory phase(2.5±0.7 and 2.5±0.7)(P=0.000). In the mid-secretory phase, the protein expression of integrin β3(2.0±0.9) and OPN (2.1±0.8)in eutopic endometrium of adenomyosis were significantly lower than that of control endometrium(2.7±0.5 and 2.7±0.7)(P<0.01). (2)The mRNA expression level of integrin β and OPN in eutopic and ectopic endometrium were assessed by quantitative real-time PCR(result was shown by median index). It was observed that integrin β3 mRNA and OPN mRNA were significantly lower in the eutopic endometrium of adenomyosis (4.69 and 4.23), when compared with ectopic endometrium(7.96 and 14.84)and controls (13.47 and 17.40) (P<0.05). Eutopic endometrium had higher mRNA expression of integrin β and OPN mRNA in the secretory phase (5.54 and 11.40) than that in the proliferative phase(2.69 and 3.30) (P<0.01).The mRNA expression level of integrin β and OPN of control endometrium in the proliferative phase (3.12 and 4.75)were significantly lower than that in the secretory phase(19.94 and 21.00, P=0.000). The mRNA expression of integrin β and OPN were 10.10 and 14.34 in the mid-secretory phase, which were significantly lower than 21.50 and 24.18 in control endometrium(P<0.05). Conclusions High expression of integrin β3 and OPN in ectopic endometrium of adenomyosis may cause endometriotic lesions; abnormal expression of integrin β3 and OPN in the endometrium of adenomyosis during the implantation window may contribute to infertility in some patients.

孕激素受体亚型在子宫腺肌病中的表达及意义

目的了解孕激素受体亚型(PR-A、PR-B)在子宫腺肌病异位病灶、在位内膜中的表达,探讨其在子宫腺肌病发生及治疗中的作用。方法采用免疫组化抗生物素蛋白-过氧化物酶染色法(SP法)检测子宫腺肌病患者(21例)病灶及其在位内膜及对照组(19例)子宫内膜标本中孕激素受体亚型的表达。结果PR-A、PR-B蛋白在异位病灶中广泛表达,表达强度显著低于其在位内膜和对照组内膜。研究组在位内膜间质内PR-A蛋白表达明显低于对照组在位内膜。结论异位病灶内PR蛋白的低表达及研究组在位内膜间质PR-A蛋白的低表达可能参与了该病的发病过程,可能与"孕激素抵抗"有关。
