Abstract

The small nuclear ribonucleoprotein polypeptide N (SNRPN) gene, encoding the RNA-associated SmN protein, duplications or deletions of which are strongly associated with neurodevelopmental disabilities. SNRPN-coding protein is highly expressed in the brain. However, the role of SNRPN protein in neural development remains largely unknown. Here we showed that the expression of SNRPN increased markedly during postnatal brain development. Overexpression or knockdown of SNRPN in cortical neurons impaired neurite outgrowth, neuron migration and the distribution of dendritic spines. We found that SNRPN regulated the expression level of Nr4a1, a critical nuclear receptor during neural development, in cultured primary cortical neurons. The abnormal spine development caused by SNRPN overexpression could be fully rescued by Nr4a1 co-expression. Importantly, we found that either knockdown of Nr4a1 or 3, 3′- Diindolylmethane (DIM), an Nr4a1 antagonist, were able to rescue the effects of SNRPN knockdown on neurite outgrowth of embryonic cortical neurons, providing the potential therapeutic methods for SNRPN deletion disorders. We thus concluded that maintaining the proper level of SNRPN is critical in cortical neurodevelopment. Finally, Nr4a1 may serve as a potential drug target for SNRPN-related neurodevelopmental disabilities, including Prader-Willi syndrome (PWS) and autism spectrum disorders (ASDs).

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.
