对HIF1α氧化和蛋白质体降解的研究.
对NDRG1-HIF1α轴的遗传淘汰和药理抑制 (Voglibose) 的研究.
评估肺血管改造和右心室缩.

主要成果:

急性缺氧通过mTORC2-依赖酸化增加了NDRG1的稳定性.
慢性缺氧通过HIF1α结合增强了NDRG1转录.
NDRG1 抑制了 HIF1α 林氧化和降解,稳定了 HIF1α.
HIF1α稳定促进了肺动脉内皮细胞的增殖和代谢重编程.
干扰NDRG1-HIF1α轴减弱了PH进展,减少了血管重塑和右心室缩.

结论:

在PH低氧信号传输中发现了一种新的前NDRG1-HIF1α调节电路.
这一途径对于PH的发展和进步至关重要.
针对NDRG1-HIF1α轴,可能使用Voglibose,显示了PH管理的治疗前景.

关键词:

这就是HIF1α.氧气过低是因为缺氧.在 NDRG1 中,没有了,没有了,没有了.后翻译修改后的修改.这就是ROSOS ROS.

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...

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...
