Description
Tip60 is a key histone acetyltransferase (HAT) enzyme that plays a central role in diverse biological processes critical for general cell function, however the chromatin-mediated cell-type specific developmental pathways that are dependent exclusively upon the HAT activity of Tip60 remain to be explored. Here, we investigate the role of Tip60 HAT activity in transcriptional control during multicellular development, in vivo by examining genome-wide changes in gene expression in a Drosophila model system specifically depleted for endogenous dTip60 HAT function. We show that amino acid residue E431 in the catalytic HAT domain of dTip60 is critical for the acetylation of endogenous histone H4 in our fly model in vivo, and demonstrate that dTip60 HAT activity is essential for multicellular development. Moreover, our results uncover a novel role for Tip60 HAT activity in controlling neuronal specific gene expression profiles essential for nervous system function as well as a central regulatory role for Tip60 HAT function in general metabolism.

Description
Human embryonic stem cells (hESCs) were specified as ventral telencephalic neuroectoderm (day 4) and then into medial ganglionic emininence (MGE)-like progenitors (day 15) and were subsequently differentiated into cortical interneuron (cIN)-like cells (day 25-35), by modification of previously published protocols. RNA-seq analysis at days 0, 4, 15, 25, and 35 defined transcriptome signatures for MGE and cIN cell identity. Further integration of these gene expression signatures with ChIP-seq for the NKX2-1 transcription factor in MGE-like progenitors defined NKX2-1 putative direct targets, including genes involved in both MGE specification and in several aspects of later cIN differentiation (migration, synaptic function). Among the NKX2-1 direct targets with MGE and cIN enriched expression was CHD2, a chromatin remodeling protein. Since CHD2 haploinsufficiency can cause epilepsy and/or autism, which can involve altered cIN development or function, we evaluated CHD2 requirements in these processes. Transcriptome changes were evaluated in CHD2 knockdown MGE-like progenitors at day 15, revealing diminished expression of genes involved in MGE specification and cIN differentiation including channel and synaptic genes implicated in epilepsy, while later cIN electrophysiological properties were also altered. We defined some shared cis-regulatory elements bound by both NKX2-1 and CHD2 and characterized their ability to cooperatively regulate cIN gene transcription through these elements. We used these data to construct regulatory networks underlying MGE specification and cIN differentiation and to define requirements for CHD2 and its ability to cofunction with NKX2-1 in this process. Overall design: To comprehensively define changes in gene expression profiles that accompany cortical interneuron (cIN) specification and differentiation process, we have performed RNA sequencing analysis at days 0 (hESCs), 4, 15, 25, and 35. To understand the gene regulatory networks through which NKX2-1 may directly control these processes, we defined its direct targets by performing NKX2-1 ChIP-seq in day 15 MGE-like cells. Chromatin enrichment for NKX2-1 binding was compared to input and IgG controls. To define the CHD2-dependent gene expression programs during cIN specification, we used CHD2 knockdown (KD) to conduct RNA-seq analysis in d15 CHD2 KD MGE-like cells.

Description
The study was completed to compare expression profiles of primary human beta cells (in the form of adult human islets), to the expression profile of hESC-derived beta-like cells. A HES3 line modified by homologous recombination to express GFP under the insulin promoter allowed us to FACS sort the hESC-derived cells into purified insulin-positive (presumably beta-like cells), and insulin-negative populations.

Description
Organoid techniques provide unique platforms to model brain development and neurological disorders. While organoids recapitulating corticogenesis were established, a system modeling human medial ganglionic eminence (MGE) development, a critical ventral brain domain producing cortical interneurons and related lineages, remains to be developed. Here, we describe a system to generate MGE or cortex-specific organoids from human pluripotent stem cells. These organoids recapitulate the developments of MGE and cortex domains respectively. Population and single-cell transcriptomic profiling revealed transcriptional dynamics and lineage productions during MGE and cortical organoids development. Chromatin accessibility landscapes were found to be involved in this process. Furthermore, MGE and cortical organoids generated physiologically functional neurons and neuronal networks. Finally, we applied fusion organoids as a model to investigate human interneuron migration. Together, our study provides a new platform for generating domain-specific brain organoids, for modeling human interneuron migration, and offers deeper insight into molecular dynamics during human brain development. Overall design: mRNA profiles of hMGEOs and hCOs were generated by deep sequencing
