摘要:
背景: background: 最近的证据表明,puerarin具有保护性效应的效应。 In the present study, we aimed to investigate whether Puerarin could protect pulmonary arterial endothelial cells from hypoxic injury and determine its potential targets.
METHODS: In our study, human pulmonary arterial endothelial cells (HPAECs) were injured by hypoxic (1% O) incubat离子。通过细胞计数试剂盒(CCK8)检测到细胞活力。通过Griess试剂检测到一氧化氮(NO)的产生,并通过ELISA方法检测到内皮素-1(ET-1)。通过荧光显微镜通过荧光探针DCFH-DA测量氧化应激。蛋白质印迹用于研究机制。
结果: 结果表明,puerarin可保护HPAEC免受低氧诱导的凋亡的影响,并稍微提高细胞的纤维固醇。瓜素增加NO并减少ET-1,以防止HPAEC中缺氧引起的血管活性物质之间的失衡。瓜素还抑制缺氧引起的氧化应激。 The results from the Western blot show that Puerarin activates the BMPRII/Smad and PPARγ/PI3K/Akt signaling pathways.
CONCLUSION: In conclusion, Puerarin protects HPAECs from hypoxic injury through the inhibition of oxidativeBMPRII和PPARγ信号通路的应力和激活。这项工作提供了对瓜素蛋白的发展的洞察力,以治疗低氧肺动脉高压。
