基于斑马鱼的对香豆酸甲酯的抗血管新生活性研究

基于斑马鱼的对香豆酸甲酯的抗血管新生活性研究(任务书,开题报告,外文翻译,论文9000字)
摘 要
血管生成是许多生理和病理过程中的关键一环。血管抑制活性化合物可作为治疗异常血管生成疾病的治疗药物。对香豆酸甲酯（pCAME）是闭鞘姜（Koen）Sm的成分（姜科）。 闭鞘姜是生长在菲律宾，印度，斯里兰卡和马来西亚的一种草本植物。种植物的根茎可以用于治疗蠕虫，消化不良，卡他性发热和一些皮肤病。已有研究，pCAME具有抗黑变性，抗氧化性和抗微生物活性，引起了我们对其血管活性的研究的兴趣。
斑马鱼因为其基因与哺乳类动物具有高度保守性这一特点使之成为研究化学物质临床安全性的理想生物模型。本实验选择了转基因斑马鱼（fli-1：EGFP）模型，发现pCAME抑制了斑马鱼发育中体节间与肠下网血管的生成。为进一步研究，我们选用了vegfa，ang-1，ang-2及其受体flt-1，flk-1，tie-1，tie-2血管发育相关基因作为代表来研究pCAME诱导抗血管生成的分子机制。发现pCAME抑制了vegf / vegfr和ang / tie信号通路的表达。PCAME有成为血管生成抑制剂的潜能，可作为先导化合物开发成抗血管生成药物。

ABSTRACT
Angiogenesis is a key link in many physiological and pathological processes. Angiostatic compounds can be used as therapeutic agents for treating abnormal angiogenic diseases.Methyl coumarate (pCAME) is a component of Koen Sm (Gingeraceae). Ginger is a herb that grows in the Philippines, India, Sri Lanka and Malaysia. The rhizomes of the plants can be used to treat worms, indigestion, catarrhal fever and some skin diseases. It has been studied that pCAME has anti-blackening, anti-oxidation and anti-microbial activity, which has aroused our interest in the study of its vasoactive activity.
Zebrafish is an ideal biological model for studying the clinical safety of chemical substances due to its highly conserved nature of mammals and mammals. In this experiment, the transgenic zebrafish (fli-1:EGFP) model was selected and it was found that pCAME inhibited the formation of intravascular and subinvasive vasculature in zebrafish development. For further study, we used vegfa, ang-1, ang-2 and its receptors flt-1, flk-1, tie-1, tie-2 angiogenesis-related genes as representatives to study pCAME-induced anti-angiogenic molecules. mechanism. It was found that pCAME inhibits the expression of vegf / vegfr and ang / tie signaling pathways. PCAME has the potential to become an angiogenesis inhibitor and can be developed as an anti-angiogenic agent as a lead compound. [版权所有：http://DOC163.com]
