为了更好地了解细胞对DNA复制应激的反应在胚胎发育过程中是如何调节的,我们和其他人建立了早期C。线虫胚胎作为模型系统来研究这一重要问题。与大多数真核细胞类型一样,复制应激反应由早期蠕虫胚胎中的ATR激酶控制。在这份报告中,我们使用RNAi系统地表征ATR途径组分在复制应激反应过程中促进细胞周期延迟的作用,我们发现这些遗传要求各不相同,这取决于应激源。我们还研究了胚胎内的单个细胞类型如何对复制应激做出反应,并且我们发现反应的强度(由细胞周期延迟的持续时间定义)在早期胚胎的卵裂球内变化很大。我们的研究揭示了在胚胎发育的背景下如何管理复制应激反应,并表明这一途径受到发育调控。
To better understand how the cellular response to DNA replication stress is regulated during embryonic development, we and others have established the early C. elegans embryo as a model system to study this important problem. As is the case in most eukaryotic cell types, the replication stress response is controlled by the ATR kinase in early worm embryos. In this report we use RNAi to systematically characterize ATR pathway components for roles in promoting cell cycle delay during a replication stress response, and we find that these genetic requirements vary, depending on the source of stress. We also examine how individual cell types within the embryo respond to replication stress, and we find that the strength of the response, as defined by duration of cell cycle delay, varies dramatically within blastomeres of the early embryo. Our studies shed light on how the replication stress response is managed in the context of embryonic development and show that this pathway is subject to developmental regulation.
