项目摘要

PROJECT SUMMARY Neurodevelopmental disorders (NDDs), are increasingly recognized as originating from dysregulation of early brain development, which represents a window of vulnerability to environmental compounds. Environmental compounds may alter neurodevelopment via epigenetic mechanisms, which may not induce massive cell death, but change the brain function through their epigenetic effect on stem cell fate and lineage development. However, tools to systematically examine the epigenetic impact of environment on neurodevelopment are lacking. Here we employ Microscopic Imaging of Epigenetic Landscape (MIEL) to screen ToxCast e1k chemical library (1800 compounds) and to characterize hits that alter epigenetic landscape of human neural precursors without inducing cytotoxicity. Recognizing environmental insults and understanding their mechanism of action will enable the development of regulations and guidelines aimed at avoiding such insults and the development of antidotes and protective agents when exposure is unavoidable.

项目摘要神经发育障碍（NDDS）越来越多地被认为是源于早期失调大脑发育，代表着脆弱性环境化合物的窗口。环境的化合物可能通过表观遗传机制改变神经发育，这可能不会诱导大量细胞死亡，但通过对干细胞命运和谱系发育的表观遗传作用来改变大脑功能。但是，系统地检查环境对神经发育的表观遗传影响的工具是缺乏。在这里，我们采用表观遗传景观（MIEL）的微观成像来筛选Toxcast E1K 化学库（1800种化合物），并表征改变人类神经表观遗传景观的命中前体无诱导细胞毒性。认识到环境侮辱并理解他们的行动机制将使旨在避免此类侮辱的法规和准则的制定制定当暴露不可避免时，解毒剂和保护剂的发展。
