Ezh2, the histone methyltransferase of PRC2, regulates the balance between self-renewal and differentiation in the cerebral cortex
Open accessAbstract
Multipotent progenitor cells of the cerebral cortex balance self-renewal and differentiation to produce complex neural lineages in a fixed temporal order in a cell-autonomous manner. We studied the role of the polycomb epigenetic system, a chromatin-based repressive mechanism, in controlling cortical progenitor cell self-renewal and differentiation. We found that the histone methyltransferase of polycomb repressive complex 2 (PCR2), enhancer of Zeste homolog 2 (Ezh2), is essential for controlling the rate at which development progresses within cortical progenitor cell lineages. Loss of function of Ezh2 removes the repressive mark of trimethylated histone H3 at lysine 27 (H3K27me3) in cortical progenitor cells and also prevents its establishment in postmitotic neurons. Removal of this repressive chromatin modification results in marked up-regulation in gene expression, the consequence of which is a shift in the balance between self-renewal and differentiation toward differentiation, both directly to neurons and indirectly via basal progenitor cell genesis. Although the temporal order of neurogenesis and gliogenesis are broadly conserved under these conditions, the timing of neurogenesis, the relative numbers of different cell types, and the switch to gliogenesis are all altered, narrowing the neurogenic period for progenitor cells and reducing their neuronal output. As a consequence, the timing of cortical development is altered significantly after loss of PRC2 function.

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.
