Abstract

Angiogenesis is a key process in embryonic development, a disruption of this process can lead to severe developmental defects, such as limb malformations. The identification of molecular perturbations representative of antiangiogenesis in zebrafish embryo (ZFE) may guide the assessment of developmental toxicity from an endpoint- to a mechanism-based approach, thereby improving the extrapolation of findings to humans. Thus, the aim of the study was to discover molecular changes characteristic of antiangiogenesis and developmental toxicity. We exposed ZFEs to two antiangiogenic drugs (SU4312, sorafenib) and two developmental toxicants (methotrexate, rotenone) with putative antiangiogenic action. Molecular changes were measured by performing untargeted metabolomics in single embryos. The metabolome response was accompanied by the occurrence of morphological alterations. Two distinct metabolic effect patterns were observed. The first pattern comprised common effects of two specific angiogenesis inhibitors and the known teratogen methotrexate, strongly suggesting a shared mode of action of antiangiogenesis and developmental toxicity. The second pattern involved joint effects of methotrexate and rotenone, likely related to disturbances in energy metabolism. The metabolites of the first pattern, such as phosphatidylserines, pterines, retinol, or coenzyme Q precursors, represented potential links to antiangiogenesis and related developmental toxicity. The metabolic effect pattern can contribute to biomarker identification for a mechanism-based toxicological testing.

摘要

血管生成是胚胎发育的关键过程,该过程的破坏可导致严重的发育缺陷,如肢体畸形。鉴定斑马鱼胚胎(ZFE)中抗血管生成过程的分子扰动,可能会引导从终点方法到基于机制的方法评估发育毒性,从而改善研究结果向人类的外推。因此,本研究旨在发现具有抗血管生成和发育毒性特征的分子变化。我们将 ZFE 暴露于两种抗血管生成药物(SU4312、索拉非尼)和两种具有潜在抗血管生成作用的发育毒物(甲氨蝶呤、鱼藤酮)中。通过在单个胚胎中进行非靶向代谢组学测量来检测分子变化。代谢组的变化伴随着形态改变的发生。观察到两种不同的代谢效应模式。第一种模式包括两种特定的血管生成抑制剂和已知致畸剂甲氨蝶呤的共同作用,强烈表明抗血管生成和发育毒性具有共同的作用模式。第二种模式涉及甲氨蝶呤和鱼藤酮的联合作用,可能与能量代谢紊乱有关。第一种模式的代谢物,如磷脂酰丝氨酸、蝶呤、视黄醇或辅酶 Q 前体,可能与抗血管生成和相关发育毒性有关。代谢效应模式有助于基于机制的毒理学测试的生物标志物鉴定。
