Abstract

Increased cortical size is essential to the enhanced intellectual capacity of primates during mammalian evolution. The mechanisms that control cortical size are largely unknown. Here, we show that mammalian BAF170, a subunit of the chromatin remodeling complex mSWI/SNF, is an intrinsic factor that controls cortical size. We find that conditional deletion of BAF170 promotes indirect neurogenesis by increasing the pool of intermediate progenitors (IPs) and results in an enlarged cortex, whereas cortex-specific BAF170 overexpression results in the opposite phenotype. Mechanistically, BAF170 competes with BAF155 subunit in the BAF complex, affecting euchromatin structure and thereby modulating the binding efficiency of the Pax6/REST-corepressor complex to Pax6 target genes that regulate the generation of IPs and late cortical progenitors. Our findings reveal a molecular mechanism mediated by the mSWI/SNF chromatin-remodeling complex that controls cortical architecture.

  • SMARCC2 encodes a subunit of the chromatin remodeling complex mSWI/SNF that directly controls neurogenesis in the developing cerebral cortex by regulating its size and thickness.

    “Interestingly, one positively selected site was also detected in SMARCC2, which encodes a subunit of the chromatin remodeling complex mSWI/SNF that directly controls neurogenesis in the developing cerebral cortex by regulating its size and thickness44.”

    From Distinct selective forces and Neanderthal introgression shaped genetic diversity at genes involved in neurodevelopmental disorders (2017) · cites this paper as [44]

    The Abstract and Discussion identify BAF170 as an mSWI/SNF subunit that controls cortical neurogenesis, with consequences for cortical size and thickness. Our copy does not identify BAF170 as the product of SMARCC2, and it describes neurogenesis as affecting cortical dimensions rather than being controlled by them. (LLM, conf=0.84)

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.
