着床需要接受性子宫内膜和健康胚泡之间的沟通。这种母胚串扰涉及子宫微环境内的局部介质。我们证明,分泌蛋白,prokineticin 1(PROK 1),在接受性子宫内膜和妊娠早期表达。PROK 1通过Gq-Ca 2 +-cSrc-丝裂原活化蛋白激酶激酶介导的途径诱导子宫内膜上皮细胞和早孕蜕膜中白血病抑制因子(LIF)的表达我们发现,人胚胎绒毛膜促性腺激素(hCG)诱导PROK 1和LIF在体内狒狒模型,在人子宫内膜上皮细胞,并在第一个三个月的蜕膜连续mRNA表达。我们已经使用靶向PROK 1的microRNA构建体来证明hCG介导的LIF在子宫内膜中的表达依赖于PROK 1的预先诱导。双免疫组化分析共定位表达促黄体激素/绒毛膜促性腺激素受体,PROK 1,PROKR 1,和LIF的腺上皮细胞的第一个三个月的蜕膜组织。PROK 1增强滋养层细胞与纤连蛋白和层粘连蛋白基质的粘附,其主要通过LIF诱导介导。这些数据描述了一种介导母胚串扰的新型信号通路,其中胚胎hCG通过子宫内膜PROK 1可能在增强容受性和维持早期妊娠方面发挥关键作用。Evans,J.,卡塔拉诺河D、Brown,P.,舍温河,克里奇利,H。O.

Implantation requires communication between a receptive endometrium and a healthy blastocyst. This maternal-embryonic crosstalk involves local mediators within the uterine microenvironment. We demonstrate that a secreted protein, prokineticin 1 (PROK1), is expressed in the receptive endometrium and during early pregnancy. PROK1 induces expression of leukemia inhibitory factor (LIF) in endometrial epithelial cells and first trimester decidua via a Gq-Ca2+-cSrc-mitogen-activated protein kinase kinase-mediated pathway. We show that human embryonic chorionic gonadotropin (hCG) induces sequential mRNA expression of PROK1 and LIF in an in vivo baboon model, in human endometrial epithelial cells, and in first-trimester decidua. We have used micro RNA constructs targeted to PROK1 to demonstrate that hCG-mediated LIF expression in the endometrium is dependent on prior induction of PROK1. Dual immunohistochemical analysis colocalized expression of the luteinizing hormone/chorionic gonadotropin receptor, PROK1, PROKR1, and LIF to the glandular epithelial cells of the first trimester decidual tissue. PROK1 enhances adhesion of trophoblast cells to fibronectin and laminin matrices, which are mediated predominantly via LIF induction. These data describe a novel signaling pathway mediating maternal-embryonic crosstalk, in which embryonic hCG via endometrial PROK1 may play a pivotal role in enhancing receptivity and maintaining early pregnancy.—Evans, J., Catalano, R.
