Abstract Coronary heart disease (CHD) is a leading cause of death worldwide, and angiogenesis plays important roles in CHD. Thus, in the present study, the angiogenic efficacy of four common cardiovascular medicines (aspirin, pravastatin, metoprolol and isosorbide mononitrate (ISMN)) was determined by the number and length of zebrafish intersegmental vessels (ISVs) after immersing zebrafish embryos in different medicines. Results showed that ISMN significantly increased the length and number of ISVs. ISMN is a long-acting nitrate ester drug. It has been used as a vasodilator to dilate arteries and veins to reduce the cardiac preload and postload. However, the effect of ISMN on angiogenesis remains unclear. Thus, by in vitro experiments, the angiogenic mechanism of ISMN was evaluated through detecting the viability and proliferation of human umbilical vein endothelial cells (HUVECs) and the expression of angiogenesis-related genes and miRNAs. Results indicated that ISMN could increase the viability and proliferation of HUVECs by decreasing apoptosis, and elevated the expressions of vedf, kdrl, pdgfr in zebrafish embryos. Furthermore, the expressions of miR-126, miR-130a and miR-210 were also regulated in ISMN-treated HUVECs. In conclusion, ISMN could promote angiogenesis in zebrafish embryos and HUVECs, implying ISMN may be a potential therapeutic in treating angiogenesis-related diseases.

单硝酸异山梨酯促进斑马鱼胚胎发育中的血管生成

摘要 冠心病(coronary heart disease,CHD)是世界范围内的主要死亡原因,血管生成在冠心病中起着重要作用。因此,在本研究中,四种常见心血管药物(阿司匹林、普伐他汀、美托洛尔和单硝酸异山梨酯 (ISMN))的血管生成功效由将斑马鱼胚胎浸入不同药物后斑马鱼节间血管 (ISV) 的数量和长度决定。结果表明,ISMN 显着增加了 ISV 的长度和数量。ISMN 是一种长效硝酸酯类药物。它已被用作扩张动脉和静脉的血管扩张剂,以减少心脏前负荷和后负荷。然而,ISMN 对血管生成的影响仍不清楚。因此,通过体外实验,通过检测人脐静脉内皮细胞(HUVECs)的活力和增殖以及血管生成相关基因和miRNA的表达来评估ISMN的血管生成机制。结果表明,ISMN可以通过减少细胞凋亡来增加HUVECs的活力和增殖,并上调斑马鱼胚胎中vedf、kdrl、pdgfr的表达。此外,miR-126、miR-130a 和 miR-210 在 ISMN 处理的 HUVEC 中的表达也受到调节​​。总之,ISMN 可以促进斑马鱼胚胎和 HUVEC 的血管生成,这意味着 ISMN 可能是治疗血管生成相关疾病的潜在疗法。结果表明,ISMN可以通过减少细胞凋亡来增加HUVECs的活力和增殖,并上调斑马鱼胚胎中vedf、kdrl、pdgfr的表达。此外,miR-126、miR-130a 和 miR-210 在 ISMN 处理的 HUVEC 中的表达也受到调节​​。总之,ISMN 可以促进斑马鱼胚胎和 HUVEC 的血管生成,这意味着 ISMN 可能是治疗血管生成相关疾病的潜在疗法。结果表明,ISMN可以通过减少细胞凋亡来增加HUVECs的活力和增殖,并上调斑马鱼胚胎中vedf、kdrl、pdgfr的表达。此外,miR-126、miR-130a 和 miR-210 在 ISMN 处理的 HUVEC 中的表达也受到调节​​。总之,ISMN 可以促进斑马鱼胚胎和 HUVEC 的血管生成,这意味着 ISMN 可能是治疗血管生成相关疾病的潜在疗法。
