CHD5 is required for neurogenesis and has a dual role in facilitating gene expression and polycomb gene repression.
The chromatin remodeler CHD5 is expressed in neural tissue and is frequently deleted in aggressive neuroblastoma. Very little is known about the function of CHD5 in the nervous system or its mechanism of action. Here we report that depletion of Chd5 in the developing neocortex blocks neuronal differentiation and leads to an accumulation of undifferentiated progenitors. CHD5 binds a large cohort...
متن کاملThe imprinted polycomb group gene Sfmbt2 is required for trophoblast maintenance and placenta development.
Imprinted genes play important roles in placenta development and function. Parthenogenetic embryos, deficient in paternally expressed imprinted genes, lack extra-embryonic tissues of the trophoblast lineage. Parthenogenetic trophoblast stem cells (TSCs) are extremely difficult to derive, suggesting that an imprinted gene(s) is necessary for TSC establishment or maintenance. In a candidate study...
متن کاملPolycomb Group Gene rae28 Is Required for Sustaining Activity of Hematopoietic Stem Cells
The rae28 gene (rae28), also designated as mph1, is a mammalian ortholog of the Drosophila polyhomeotic gene, a member of Polycomb group genes (PcG). rae28 constitutes PcG complex 1 for maintaining transcriptional states which have been once initiated, presumably through modulation of the chromatin structure. Hematopoietic activity was impaired in the fetal liver of rae28-deficient animals (rae...
متن کاملPolycomb group gene expression in the sea urchin.
Embryonic development in metazoan animals involves a remarkable degree of both genetic and epigenetic regulation. Polycomb group (PcG) genes are essential for initiation and maintenance of epigenetic developmental regulation. This report identifies homologous PcG genes representing the core components of three known Polycomb repressive complexes in the sea urchin Strongylocentrotus purpuratus. ...
متن کاملThe Polycomb-group gene Rae28 sustains Nkx2.5/Csx expression and is essential for cardiac morphogenesis.
The Polycomb-group (PcG) gene Rae28 is a mammalian homologue of the Drosophila gene polyhomeotic. PcG genes are known to maintain transcription states, once initiated, probably by regulating chromatin structure. Since homozygous Rae28-deficient (Rae28(-/-)) mice displayed cardiac anomalies similar to congenital heart diseases in humans, we examined the role of Rae28 in cardiac morphogenesis at ...
