铅是一种剧毒金属,具有发育神经毒性。Ambra1在胚胎神经发育中起着至关重要的作用。目前,Ambra1在铅致发育神经毒性中的作用尚不清楚。在本研究中,我们探讨了Ambra1在铅致神经毒性中的作用机制。斑马鱼(Danio Rerio)胚胎暴露于0.1%、1%和10%μM和铅,直到受精后5d,其运动活动明显受到10μM处理的影响。同时,在受精后48小时和72小时,铅降低了脑组织中ambra1和ambra1的表达。在染铅的斑马鱼中,ambra1orambra1的过表达缩短了铅诱导的运动活动的改变,并减少了脑组织中的凋亡细胞数量。我们的数据揭示了Ambra1对发育中的斑马鱼铅诱导的神经损伤的一种新的保护作用。
Lead is a highly toxic metal that displays developmental neurotoxicity. Ambra1 plays a crucial role in embryonic neural development. At present, the role of Ambra1 in lead-induced developmental neurotoxicity remains unknown. In this study, we investigated the mechanism of Ambra1 concerning its role in lead-induced neurotoxicity. Zebrafish (Danio rerio) embryos were exposed to 0.1, 1, or 10 μM Pb until 5 days post-fertilization, and their locomotor activity was significantly impaired by the 10 μM treatment. Meanwhile, Pb reduced the expression ofambra1aandambra1bin the brain at 48 and 72 h post-fertilization. Overexpression ofambra1aorambra1breversed Pb-induced alterations in locomotor activity, and decreased the apoptotic cell numbers in the brains of Pb-treated zebrafish. Our data reveal a novel protective role of Ambra1 against Pb-induced neural damage in the developing zebrafish.
