Abstract

New neurons are continuously generated from neural stem cells with astrocyte properties, which reside in close proximity to the ventricle in the postnatal and adult brain. In this study we found that microRNA-124 (miR-124) dictates postnatal neurogenesis in the mouse subventricular zone. Using a transgenic reporter mouse we show that miR-124 expression is initiated in the rapid amplifying progenitors and remains expressed in the resulting neurons. When we stably inhibited miR-124 in vivo, neurogenesis was blocked, leading to the appearance of ectopic cells with astrocyte characteristics in the olfactory bulb. Conversely, when we overexpressed miR-124, neural stem cells were not maintained in the subventricular zone and neurogenesis was lost. In summary, our results demonstrate that miR-124 is a neuronal fate determinant in the subventricular zone.

  • miRNAs play an important role in neurodegenerative diseases, including ALS.

    “Growing evidence suggests that miRNAs play an important role in neurodegenerative diseases, including ALS (Akerblom et al., 2012; Goodall et al., 2013; Zhu et al., 2013; Parisi et al., 2016).”

    The Introduction and Discussion describe miR-124’s role in neuronal differentiation and neurogenesis, not in neurodegenerative disease. Searches for ALS, amyotrophic lateral sclerosis, neurodegenerative disease, and pathology found no passage connecting miRNAs to ALS or neurodegenerative diseases in our copy. (LLM, conf=0.76)

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.
