Effects of loss and gain of KAT6B on gene expression in the developing cerebral cortex [Myst4_RNAseq]

Project description:High histone acetylation is associated with high transcriptional activity. The lysine acetyltransferase KAT6B is known to be required for histone acetylation and KAT6B is essential for normal brain development. In this study we examined the effects of loss and gain of KAT6B on gene expression in the developing cerebral cortex. We isolated RNA from the dorsal telencephalon of embryonic day 12.5 embryos, which is the primordium of the cerebral cortex, and from the E15.5 foetal cortex of mouse embryos and foetuses that lacked KAT6B or overexpressed KAT6B. Genes required for brain development and neuronal differentiation were downregulated in Kat6b null tissues and upregulated in Kat6b transgenic overexpressing tissue.

Effects of loss and gain of KAT6B on gene expression in neural stem and progenitor cells [NSC_Kat6b_RNAseq]

Project description:High histone acetylation is associated with high transcriptional activity. The lysine acetyltransferase KAT6B is known to be required for histone acetylation and KAT6B is essential for normal brain development. In this study we examined the effects of loss and gain of KAT6B on gene expression in forebrain neural stem and progenitor cells (NSPCs). We isolated NSPCs from the dorsal telencephalon of embryonic day 12.5 embryos, which is the primordium of the cerebral cortex, from mouse embryos that lacked KAT6B or overexpressed KAT6B. We cultured the cells in vitro for 3 to 5 passages before isolating RNA for library production and RNA-sequencing. We found that genes required for neuronal differentiation and brain development were downregulated in Kat6b null cells and upregulated in Kat6b transgenic overexpressing cells.

Effects of loss and gain of the histone acetyltransferase KAT6B on DNA accessibility (ATAC-seq)

Project description:Heterozygous mutations in the histone acetyltransferase gene KAT6B (MYST4/MORF/QKF) cause cognitive disorders. Congruently, KAT6B is required for brain development, neural stem cell self-renewal and neuronal differentiation in mice. Despite the clear requirement for KAT6B in brain development, its molecular roles remain unexplored. Here we use ATAC sequencing to determine the effects of loss or gain of KAT6B on DNA accessiblity.

RNA sequencing of cortical neurons from Kat6b deficient mouse foetuses

Project description:The RNA sequencing data are part of a study reporting and investigating a mouse model of the Say-Barber-Biesecker-Young-Simpson (SBBYS) syndrome (OMIM:603736) and demonstrating proof-of-principle efficacy of postnatal treatment with sodium valproate (VPA) or acetyl-carnitine (ALCAR). The KAT6B gene encodes a histone lysine acetyltransferase. The RNA sequencing experiments identified genes that are differentially expressed between Vehicle treated Kat6b+/– and Kat6b+/+ cortical neurons and the subset genes that are restored to normal expression after treatment with ALCAR or VPA. Cortical neurons were isolated from four Kat6b+/– and four Kat6b+/+ E16.5 mouse cerebral cortex. Cells from each cortical neuron isolate were cultured with 1 mM ALCAR, 1 mM VPA or untreated medium (Vehicle) for 4 days.

Patterns of gene expression and evolution in the human developing cerebral cortex

Project description:The cerebral cortex underwent a rapid expansion and complexification during recent primate evolution, but the underlying developmental mechanisms remain essentially unknown. In order to uncover genetic networks underlying the development of the human cerebral cortex, we profiled the transcriptome of human fetal cortical domains containing language areas of Broca and Wernicke, as well as associative areas. We thus identified hundreds of genes displaying differential expression between the two areas or between distinct temporal stages. A subset of these genes was further validated by qRTPCR and in situ hybridization, revealing novel patterns of area and layer-specific expression throughout the developing cortex at midgestation, a critical period of cortical patterning. Computational genomic analyses revealed that the proportion of genes located close to evolutionarily accelerated regions was far more abundant among the genes differentially expressed between the two cortical areas examined, but not among those differentially expressed between different stages of development. In silico screening enabled to identify accelerated regions displaying increased turnover of change in transcription factor binding sites, which were enriched among those closer to genes differentially expressed between cortical areas. Overall our work points to the identification of cortical genes that display a unique combination of patterns of evolution and expression, which may constitute an important part of the genetic framework underlying human-specific neural traits and diseases. We determined gene expression patterns in cortical domains that contain areas thought to have undergone significant divergence during primate evolution, including language areas of Broca and Wernicke, as well as association areas of the frontal and parieto-temporal cortex in the right and left sides of human fetal brains at 17 and 19 gestional weeks.

MYST4 (QKF/KAT6B/MORF) transcriptional targets in the adult dorsal cortex and E12.5 embryonic dorsal telencephalon

Project description:MYST4 (QKF/KAT6B/MORF) is an important regulator of brain development and function through its regulation of gene expression. Genetic targets of MYST4 are currently unknown. We have therefore carried out microarrays comparing gene expression in wild type and Qkf mouse tissues, namely the dorsal cortex and E12.5 dorsal telencephalon, to elucidate genetic targets of MYST4. RNA was extracted for hybridization to arrays from 3 pairs of wild type and Qkf gt/gt mutant adult dorsal corticies and 3 pairs of wild type and Qkf gt/gt mutant E12.5 dorsal telencephalons

TRNP1 regulates expansion and folding of the mammalian cerebral cortex by control of radial glial fate

Project description:Evolution of the mammalian brain encompassed a remarkable increase in size of cerebral cortex, including tangential and radial expansion, but the mechanisms underlying these key parameters are still largely unknown. Here, we identified the novel DNA associated protein TRNP1 as a regulator of cerebral cortical expansion in both these dimensions. Gain and loss of function experiments in the mouse cerebral cortex in vivo demonstrate that high Trnp1 levels promote neural stem cell self-renewal and tangential expansion, while lower levels promote radial expansion resulting in a potent increase in the generation of intermediate progenitors and outer radial glial cells resulting in folding of the otherwise smooth murine cerebral cortex. Remarkably, TRNP1 expression levels exhibit regional differences also in the cerebral cortex of human fetuses anticipating radial or tangential expansion respectively. Thus, the dynamic regulation of TRNP1 is critical to regulate tangential and radial expansion of the cerebral cortex in mammals. We performed gene expression microarray analysis on embryonic mouse cerebral cortex derived from Trnp1 knockdown and control animals.
