Abstract

De novo mutations in CHD8 are strongly associated with autism spectrum disorder, but the basic biology of CHD8 remains poorly understood. Here we report that Chd8 knockdown during cortical development results in defective neural progenitor proliferation and differentiation that ultimately manifests in abnormal neuronal morphology and behaviors in adult mice. Transcriptome analysis revealed that while Chd8 stimulates the transcription of cell cycle genes, it also precludes the induction of neural-specific genes by regulating the expression of PRC2 complex components. Furthermore, knockdown of Chd8 disrupts the expression of key transducers of Wnt signaling, and enhancing Wnt signaling rescues the transcriptional and behavioral deficits caused by Chd8 knockdown. We propose that these roles of Chd8 and the dynamics of Chd8 expression during development help negotiate the fine balance between neural progenitor proliferation and differentiation. Together, these observations provide new insights into the neurodevelopmental role of Chd8.

  • The Wnt signaling pathway plays a crucial role in neuronal progenitor proliferation and differentiation in the forebrain.

    “One of the risk genes, Chd8, encodes a protein that binds directly to β-catenin to recruit histone proteins and negatively regulates the Wnt signaling pathway, which plays a crucial role in neuronal progenitor proliferation and differentiation in the forebrain (39–42).”

  • Knockdown of CHD8 in adult mice leads to disruption of Wnt signaling and abnormal neural progenitor cell proliferation.

    “For example, knockdown of CHD8 in adult mice leads to a disruption of Wnt signaling and abnormal NPC proliferation (Durak et al., 2016).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
