Abstract

Transcriptional regulation plays a central role in controlling neural stem and progenitor cell proliferation and differentiation during neurogenesis. For instance, transcription factors from the nuclear factor I (NFI) family have been shown to co-ordinate neural stem and progenitor cell differentiation within multiple regions of the embryonic nervous system, including the neocortex, hippocampus, spinal cord and cerebellum. Knockout of individual Nfi genes culminates in similar phenotypes, suggestive of common target genes for these transcription factors. However, whether or not the NFI family regulates common suites of genes remains poorly defined. Here, we use granule neuron precursors (GNPs) of the postnatal murine cerebellum as a model system to analyse regulatory targets of three members of the NFI family: NFIA, NFIB and NFIX. By integrating transcriptomic profiling (RNA-seq) of Nfia- and Nfix-deficient GNPs with epigenomic profiling (ChIP-seq against NFIA, NFIB and NFIX, and DNase I hypersensitivity assays), we reveal that these transcription factors share a large set of potential transcriptional targets, suggestive of complementary roles for these NFI family members in promoting neural development.

  • Although their loci are not very near to each other, Nfia, Nfib and Nfix regulate cell-type differentiation in many tissues, function as homo- or heterodimers, and bind to largely common targets.

    “Although their loci are not very near to each other, Nfia, Nfib and Nfix regulate cell-type differentiation in many tissues94–96, function as homo- or heterodimers, and bind to largely common targets97.”

    The Results (page unavailable) show substantial overlap in NFIA, NFIB and NFIX binding sites in postnatal cerebellar cells. The Discussion (page unavailable) says heterodimerisation is known in vitro but its prevalence in vivo is unclear; it does not establish that these proteins function as heterodimers in vivo or address homodimerisation. The earlier claims about locus proximity and differentiation across tissues carry different citations and are not assessed here. (LLM, conf=0.88)

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.
