概括
低氧诱导因子1α (HIF-1α) 通过调节自增强了雅克卵细胞的成熟和胚胎发育. 这项研究探讨了HIF-1α.
科学领域:
- 动物生殖生物学 动物生殖生物学
- 细胞和分子机制的机制
- 辅助生殖技术是一种辅助生殖技术.
背景情况:
- 高质量的卵细胞对于动物的辅助生殖技术至关重要.
- 雅克的生殖细胞受到缺氧诱导因子1α (HIF-1α) 的影响,因为它们适应了青海-西藏高原.
- 自对卵细胞的质量和发育起着重要作用.
研究的目的:
- 在体外研究HIF-1α对蛋细胞成熟和早期胚胎发育的影响.
- 阐明自在调解HIF-1α对雅克卵细胞影响中的作用.
- 探索改善雅克辅助生殖的潜在策略.
主要方法:
- 雅克卵细胞的体外成熟.
- 使用HIF-1α诱导剂 (DFOM) 和抑制剂 (LW6) 的治疗.
- 评估卵细胞成熟,早期胚胎发育,自标志物,CYP450s酶表达和累积扩张因子.
- 在DFOM治疗期间使用3-MA抑制自.
主要成果:
- DFOM上调HIF-1α,增加累积膨胀,第一个极体驱逐率,线粒体和动素水平,同时降低ROS和亡.
- DFOM促进了与自相关的蛋白质,CYP450s酶和累积膨胀因子,增强了卵细胞成熟和胚胎发育.
- 而LW6则表现出相反的效果;在DFOM治疗期间用3-MA抑制自,模仿了LW6对发育和亡增加的负面影响.

Regulation of Angiogenesis and Blood Supply
2.5K
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...

Oogenesis
63.6K
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...
