PURPOSE To examine the expression of MUC16 in the endometrium peri-implantation period in three different cohort studies. METHODS This was a retrospective observational cohort study. A total of 245 participants were recruited in three separate cohort studies: (1) women with recurrent miscarriage (n = 50) and fertile controls (n = 29); (2) women who had high (n = 20) or normal (n = 20) progesterone on the day of hCG trigger in ovarian stimulation cycle for IVF; and (3) women who did (n = 95) or did not (n = 31) conceive following frozen embryo transfer in HRT cycles. All subjects had archived endometrial samples precisely taken on LH+7 in natural cycles, or hCG+6 in ovarian stimulation cycles, or P+5 in HRT cycles. The H-score (median, range) of MUC16 in the luminal epithelium and glandular epithelium was determined by using immunohistochemistry. RESULTS The median (range) of H-score of MUC16 in the luminal epithelium (1) in women with recurrent pregnancy loss was 23.7 (0-300), which was significantly (P < 0.05) lower than that of 118.4 (7.7-300) in fertile controls; (2) in women with elevated progesterone on the day of hCG administration (147.8, 18.0-230.1), significantly (P < 0.05) higher than that of women with normal progesterone (61.0, 2.3-205.3); (3) in women who conceived (23.1, 0-250.3), significantly (P < 0.001) lower than that in women who did not conceive (58.4, 0-300). CONCLUSION The expression of MUC16 in all three cohort studies is consistent with it being an inhibitor of implantation.

来自三项有关植入时周围MUC16表达的队列研究的证据表明,它是植入的抑制剂。

目的在三项不同的队列研究中研究MUC16在子宫内膜着床期的表达。方法这是一项回顾性观察队列研究。在三项单独的队列研究中共招募了245名参与者:(1)反复流产(n = 50)和可育对照(n = 29)的女性;(2)在IVF卵巢刺激周期中,在hCG触发之日孕激素水平高(n = 20)或正常(n = 20)的妇女;(3)在HRT周期中冷冻胚胎移植后怀孕(n = 95)或未怀孕(n = 31)的妇女。所有受试者均存档了子宫内膜样品,分别在自然周期的LH + 7或卵巢刺激周期的hCG + 6或HRT周期的P + 5上精确采集。使用免疫组织化学测定腔上皮和腺上皮中MUC16的H值(中位数,范围)。结果复发性流产的女性管腔上皮(1)中MUC16的H值中位数(范围)为23.7(0-300),比118.4(7.7-300)显着降低(P <0.05) )在肥沃的控制中;(2)在给予hCG时孕酮升高的女性中(147.8,18.0-230.1),显着(P <0.05)高于正常孕激素的女性(61.0,2.3-205.3);(3)受孕妇女(23.1,0-250.3)显着(P <0.001)低于未受孕妇女(58.4,0-300)。结论在所有三个队列研究中,MUC16的表达与其作为植入抑制剂是一致的。05)低于可育对照组的118.4(7.7-300);(2)在给予hCG时孕酮升高的女性中(147.8,18.0-230.1),显着(P <0.05)高于正常孕激素的女性(61.0,2.3-205.3);(3)在受孕妇女中(23.1,0-250.3),显着(P <0.001)低于未受孕妇女(58.4,0-300)。结论在所有三个队列研究中,MUC16的表达与其作为植入抑制剂是一致的。05)低于可育对照组的118.4(7.7-300);(2)在给予hCG时孕酮升高的女性中(147.8,18.0-230.1),显着(P <0.05)高于正常孕激素的女性(61.0,2.3-205.3);(3)受孕妇女(23.1,0-250.3)显着(P <0.001)低于未受孕妇女(58.4,0-300)。结论在所有三个队列研究中,MUC16的表达与其作为植入抑制剂是一致的。001)低于未受孕的女性(58.4,0-300)。结论在所有三个队列研究中,MUC16的表达与其作为植入抑制剂是一致的。001)低于未受孕的女性(58.4,0-300)。结论在所有三个队列研究中,MUC16的表达与其作为植入抑制剂是一致的。
