概括

缺氧会影响怀孕早期的 trofhoblast 功能. 一个circ-TBC1D1/miR-520h/EPHB4通路的干扰与无法解释的复发性自发性流产 (URSA) 相关,可能会损害热囊细胞和子宫动脉重塑.

科学领域:

生殖生物学生殖生物学
分子遗传学分子遗传学
产科产科产科产科产科

背景情况:

怀孕早期的缺氧严重调节了热囊细胞的功能.
热囊细胞功能的调节失调与不明原因的复发性自发性流产 (URSA) 有关.

研究的目的:

在缺氧条件下研究热囊细胞功能中的circ-TBC1D1/miR-520h/EPHB4调节轴.
探索这个轴与URSA的关联.

主要方法:

来自URSA患者和对照组的胆管组织的临床分析.
在低氧条件下 (2% O2) 使用HTR-8/SVneo热囊细胞的体外研究.
评估基因和蛋白质表达 (EPHB4,VEGFA,CD31),细胞增殖,迁移,入侵和细胞亡.

主要成果:

在URSA样本中,EPHB4被上调,抑制了热囊细胞的增殖,迁移和入侵,同时增加了亡.
circ-TBC1D1作为竞争性内源RNA (ceRNA) 作用于miR-520h,上调EPHB4的表达并影响低氧条件下的热囊细胞功能.
URSA组织显示下调的miR-520h和趋向于升高的circ-TBC1D1.1.

结论:

环-TBC1D1/miR-520h/EPHB4轴在低氧压力下调节热囊细胞功能方面发挥着作用.
这个轴的调节失调可能会通过损害外性热囊细胞功能和子宫螺旋动脉重塑来促进URSA的发病.

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
