概括

SOX18通过增加OTUB1转录来促进子宫内膜异位症 (EMS),这稳定了YAP1. 这种SOX18-OTUB1-YAP1轴的激活驱动EMS的进展,并提供了一个潜在的治疗目标.

科学领域:

妇科疾病妇科疾病
分子生物学分子生物学
癌症研究癌症研究

背景情况:

子宫内膜异位症 (EMS) 涉及子宫外的子宫内膜组织,这是一个常见的妇科疾病.
SOX18转录因子表达在宫外子宫内膜组织中升高.
SOX18在EMS病原发生中的确切作用在很大程度上仍未得到证实.

研究的目的:

研究SOX18在子宫内膜异位症中的作用和机制.
探索SOX18作为EMS治疗点的潜力.

主要方法:

免疫组织化学 (IHC) 用于分析EMS中的SOX18表达模式.
在体外测试 (细胞活力,迁移,入侵) 以评估SOX18的影响.
双化酶记者测定,ChIP和DNA拉下来确认SOX18与OTUB1促进体结合.
同免疫沉 (co-IP) 分析OTUB1-YAP1的相互作用.
在体内全移植小鼠模型来评估SOX18在EMS进展中的作用.

主要成果:

在石川细胞中,SOX18的上调促进了扩散,迁移,入侵和EMT,而敲击则产生了相反的效果.
SOX18过度表达在体内加剧了EMS,导致了显著的病理变化.
SOX18直接结合并激活OTUB1促进体,从而增加OTUB1的转录.
OTUB1使YAP1蛋白脱和稳定. 在这种过程中,OTUB1可以使YAP1蛋白脱和稳定.
SOX18通过OTUB1上调调节来调节YAP1的表达,在EMS中建立SOX18-OTUB1-YAP1轴.

结论:

通过促进OTUB1转录,SOX18有助于EMS的病变发生.
在EMS中,SOX18对Hippo/YAP1信号通路的激活至关重要.
SOX18-OTUB1-YAP1轴代表了子宫内膜异位症的潜在治疗点.

关键词:

子宫内膜异位症是什么?子宫内膜异位症是什么?河马/YAP1 的情况.在OTUB1上.这就是SOX18的SOX18.

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
