概括

伊斯坦-1 (ISM1) 通过增强cGMP生成,保护心脏免受缺血/再输 (I/R) 损伤. 在PCI后的患者中,较低的ISM1水平与更糟糕的结果相关,这表明ISM1是治疗点.

科学领域:

心脏病学心脏病学
分子生物学分子生物学
生物化学生化学

背景情况:

缺血/反 (I/R) 损伤是急性心肌梗塞反治疗的一个重要并发症.
目前对心脏I/R损伤的治疗方法有限,这凸显了对新型治疗策略的需求.
伊斯-1 (ISM1) 是一种新型的阿迪波金,已知可以调节糖脂代谢和细胞存活.

研究的目的:

研究ISM1在心脏I/R损伤中的作用和分子机制.
探索ISM1作为I/R损伤的治疗剂的潜力.
评估ISM1在急性心肌梗塞患者中的临床相关性.

主要方法:

在小鼠中使用腺相关病毒血清型9的心脏特异性ISM1过度表达和沉默.
使用新生小鼠心肌细胞 (NRCMs) 接受模拟I/R (sI/R) 损伤的体外研究.
RNA测序以确定ISM1.1.的下游途径和分子标.
在受伤小鼠和NRCM中使用复合ISM1 (rISM1) 治疗.
在PCI后的急性心肌梗塞患者中对ISM1水平的临床分析.

主要成果:

心脏ISM1过度表达减轻了I / R诱导的损伤,而沉默加剧了它.
ISM1针对αvβ5整体素,促进核转录因子Y亚单元α积累,并通过cGMP-PKG通路增加cGMP生成.
再组合ISM1的管理赋予了心脏保护作用.
在PCI后循环ISM1水平较低与临床结果较差有关.

结论:

通过cGMP-PKG信号通路,ISM1可以防止心脏I/R损伤.
ISM1显示出作为心脏I/R损伤的治疗点的潜力.
循环中的ISM1水平可以作为预测患者结果的生物标志物.

Nitric Oxide Signaling Pathway

Nitric Oxide Signaling Pathway

Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

G-Protein Gated Ion Channels

G-Protein Gated Ion Channels

GPCRs are primarily responsible for our sense of smell, taste, and vision. The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.
Sensory...
