(Submitter supplied) We show that the COMPASS family histone methyltransferase co-factor ASH2L is required in NPCs proliferation and upper layer cortical projection neurons production and position. Deletion of ASH2L impairs trimethylation of H3K4 and transcriptional machinery specifically for subsets of Wnt-β-catenin signaling, disrupting their transcription and consequently inhibiting the proliferation ability of NPCs in late stages of neurogenesis.

(Submitter supplied) To elucidate the role of H3K4 methylation in metanephros development, we selectively inactivated ASH2L, core subunit of the COMPASS complex in mice UB lineage. We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 different FACS-sorted UB lineage cells at E16.5 of the control and cKO mouse embryos.

We then performed histone H3K4me3 modification landscape profiling of the control (Hoxb7Cre-GFP+,Ash2l F/+) and mutant (Hoxb7Cre-GFP+,Ash2l F/F) FACS-sorted UB lineage cells at E16.5 by CUT&Tag-seq.

(Submitter supplied) Radial glia (RG) in the neocortex sequentially generate distinct subtypes of projection neurons, accounting for the diversity and complex assembly of cortical neural circuits. Mechanisms that drive the rapid and precise temporal progression of RG are beginning to be elucidated. Here we reveal that the RG-specific transcriptional regulator PRDM16 promotes the transition of early to late phase of neurogenesis in the mouse neocortex. more...

(Submitter supplied) De novo mutations in CHD8 are strongly associated with autism spectrum disorder (ASD), however the underlying mechanisms remain elusive. Here we report that Chd8 knockdown during cortical development results in defective neural progenitor proliferation and differentiation that ultimately manifests in abnormal neuronal morphology and behaviors in adult mice. Transcriptome analysis revealed that on the one hand Chd8 stimulates the transcription of cell cycle genes, while on the other it precludes the induction of neural specific genes by regulating the expression of PRC2 complex components. more...

(Submitter supplied) The Ash2l protein is a member of KMT2 enzyme complexes, which catalyse the (tri-)methylation of lysine 4 of Histone H3. H3K4me3 is considered a marker of actively transcribed genes. We determined changes in gene expression as a consequence of a conditional loss of Ash2l in the bone marrow. The expression data from the bone marrows of mice with floxed Ash2l exon 4 alleles without (control) or with an Mx1-Cre transgene (KO) and treated with synthetic dsRNA to induce recombination and the loss of Ash2l protein expression were compared.

(Submitter supplied) Recent evidence indicates that DROSHA, DGCR8 and DICER exert non-overlapping functions, including miRNA-independent regulatory mechanisms. It is currently unknown whether miRNA-independent functions of DGCR8 play any role in corticogenesis. Here, by phenotypic comparison of conditional knockout cortices for Dgcr8 and Dicer, we uncover that Dgcr8 deletion, in contrast to Dicer, leads to premature differentiation of neural progenitor cells and overproduction of Tbr1 positive neurons. more...

(Submitter supplied) ASH2L (Absent-Small-Homeotic-2-Like protein) is a core subunit of the COMPASS (COMplex of Proteins ASsociated with Set1) complexes, the most notable writer of the methylation of histone H3 lysine 4 (H3K4). The COMPASS complex regulates active promoters or enhancers, and its dysfunction is associated with aberrant development and disease. Here, we demonstrated that ASH2L mediated the cell invasion and migration activity of triple-negative breast cancer cells through the interaction with the COMPASS components and the target genomic regions. more...

(Submitter supplied) Chromatin regulates spatiotemporal gene expression during neurodevelopment, but it also mediates DNA damage repair crucial to proliferating neural progenitor cells (NPCs). Here, we uncover molecularly dissociable roles for nucleosome remodeler INO80 in chromatin-mediated transcriptome and genome maintenance in corticogenesis. We find that conditional Ino80 deletion from cortical NPCs impairs DNA double-strand break repair, triggering p53 activation, robust apoptosis, and microcephaly, whereas co-deletion of Trp53 with Ino80 leads to remarkable reversal of these phenotypes. more...

(Submitter supplied) Neocortical development is spatiotemporally regulated by exogenous factors, but the mechanism regulating timed specificity of neocortical mRNA translation is unknown. We find that active mRNA translation sites (polysomes) contain ribosomal protein subsets that undergo dynamic spatiotemporal rearrangements during mouse neocortical development.

(Submitter supplied) Post-translational modifications of core histones participate in controlling the expression of genes. Methylation of lysine 4 of histone H3 (H3K4) is associated with open chromatin and gene transcription. This histone mark is catalyzed by type 2 lysine methyltransferase (KMT2) complexes. In mammals, these consist of one of 6 different KMT2 enzymes, each associated with 4 core subunits, WDR5, RBBP5, ASH2L and DPY30, which are necessary for catalytic activity. more...
