Abstract

While thousands of long noncoding RNAs (lncRNAs) have been identified, few lncRNAs that control neural stem cell (NSC) behavior are known. Here, we identify Pinky (Pnky) as a neural-specific lncRNA that regulates neurogenesis from NSCs in the embryonic and postnatal brain. In postnatal NSCs, Pnky knockdown potentiates neuronal lineage commitment and expands the transit-amplifying cell population, increasing neuron production several-fold. Pnky is evolutionarily conserved and expressed in NSCs of the developing human brain. In the embryonic mouse cortex, Pnky knockdown increases neuronal differentiation and depletes the NSC population. Pnky interacts with the splicing regulator PTBP1, and PTBP1 knockdown also enhances neurogenesis. In NSCs, Pnky and PTBP1 regulate the expression and alternative splicing of a core set of transcripts that relates to the cellular phenotype. These data thus unveil Pnky as a conserved lncRNA that interacts with a key RNA processing factor and regulates neurogenesis from embryonic and postnatal NSC populations.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Non-coding RNA processing and RNA splicing showed lateral wall enrichment.

    “Lastly, non-coding RNA processing and RNA splicing showed lateral wall enrichment, consistent with the importance of non-coding RNAs in V-SVZ neurogenesis (Ramos et al., 2015; Figure 2C; Table S3).”

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.
