文题释义:

Wnt信号通路:是对控制发育起重要作用的信号途径,信号转导过程发生异常或障碍,会导致细胞生长、分化、代谢及生物学异常,通路异常与多种疾病有关。经典的Wnt信号转导途径通过β-catenin核易位,激活靶基因的转录活性,其靶基因包括参与细胞发育、细胞增殖及细胞迁移的相关因子,如c-myc、细胞周期素蛋白D1(cyclin D1)、CD44、基质裂解蛋白、基质金属蛋白酶、尿激酶型纤溶酶原激活物受体等。

子宫内膜干细胞与子宫内膜再生:子宫内膜干细胞在体外和体内实验中均显示出具有子宫内膜再生和修复功能。将人子宫内膜上皮干细胞和间充质干细胞接种到免疫缺陷小鼠肾包膜下,可以产生子宫内膜层和肌层组织。在卵巢切除的免疫缺陷小鼠中,再生的内膜有腺样结构、基质及肌层样组织,这些研究表明子宫内膜干细胞可能在子宫内膜的正常变化周期中发挥着重要作用。

Abstract:

BACKGROUND: Increasing number of genes and signaling pathways are involved in regulating stem cells periodically, and wherein Wnt/β-catenin signaling pathway is an important pathway of stem cells.
OBJECTIVE: To investigate the effects of Wnt/β-catenin signal pathway on mouse endometrial stromal cells.
METHODS: After injection of Wnt/β-catenin pathway inhibitor or activator, endometrial tissues from Balb/c mice were obtained, some of which were used for detection of invasion of endometrial stromal cells and western blot detection, and the rest of which were used for preparing animal models of endometriosis followed by immunohistochemical detection.
RESULTS AND CONCLUSION: The expression of β-catenin and GSK3β proteins was significantly higher in the activator group than the inhibitor group (P < 0.05). The number of transmembrane cells was significantly higher in the activator group than the inhibitor and control groups (P < 0.05). Immunohistochemical findings showed positive expression of E-cadherin in ectopic endometrial tissues of the inhibitory group, and strongly positive expression of vascular endothelial growth factor in ectopic endometrial tissues of the activator group. These findings indicate that Wnt/β-catenin signaling pathway may cause endometriosis by strengthening ectopic endometrial implantation, invasion and metastasis.
