Transcription profiling of mouse Ngn3-expressing pancreatic cells in a time series through embryonic development and adult islet cells

Project description:Neurogenin3 (Ngn3) is a basic helix-loop-helix transcription factor which is expressed in scattered cells in the embryonic pancreas. Mice deficient for Ngn3 fail to produce any pancreatic endocrine cells and die shortly after birth. Expression of transcription factors critical to pancreatic development (Isl1, NeuroD, Pax4, and Pax6) is missing and endocrine precursors are absent in mutant pancreatic epithelium. This study utilizes mice which were engineered to contain EGFP (Enhanced Green Fluorescent Protein) under the control of the Ngn3 promoter. In this way, cells which express Ngn3 can be FACS sorted and studied throughout embryonic development (E13.5, E14.5, E15.5, E16.5, and E17.5). EGFP positive cells from the embryonic time-points in addition to adult islets (no cells expressing Ngn3) were hybridized to the BCBC PancChip 6.0 expression microarray, thus generating a profile of gene expression during this critical stage of development of the endocrine pancreas.

Multi-site Neurogenin3 phosphorylation controls pancreatic endocrine differentiation: transcriptomic analysis of pancreatic organoids overexpressing wild type and phosphomutant Neurogenin3

Project description:The proneural transcription factor Neurogenin3 (Ngn3) plays a critical role in pancreatic endocrine cell differentiation. While previous studies have focused on Ngn3 gene function, little is known about the regulation of Ngn3 protein. Here we demonstrate that Ngn3 protein undergoes cyclin-dependent kinase (cdk)-mediated phosphorylation on multiple serine-proline sites. Replacing wild-type protein with a phosphomutant form of Ngn3 increases α-cell generation, the earliest endocrine cell type to be formed in developing pancreas. Mechanistically, preventing multi-site phosphorylation enhances Ngn3 stability and DNA binding, and promotes the expression of target genes that drive differentiation. In addition to perturbing embryonic endocrine differentiation, un(der)phosphorylated Ngn3 contributes to maintaining adult β-cell differentiation in the presence of pro-proliferation cue. Here we perform transcriptomic analysis of a low number of pancreatic organoid cells expressing wild type and phosphomutant Ngn3. Analysis of the endocrine differentiation programme activated by Ngn3 in this context revealed the cell fate plasticity of the system and demonstrated that preventing Ngn3 phosphorylation enhances endocrine gene expression.

RNA-Seq analysis of mouse small intestine enteroendocrine cells

Project description:We generated knock-in mice expressing GFP under the control of the endogenous GIP (Glucose-dependent Insulinotropic Polypeptide) promoter that enable the isolation of a purified population of small intestine K cells. Using RNA-Seq, we comprehensively characterized the transcriptomes of GIP-GFP cells as well as the entire enteroendocrine lineage derived from Neurogenin3 (Ngn3)-expressing progenitors. We interrogated the whole transcriptome of FACS-isolated small intestine GIPGFP cells using high-throughput mRNA sequencing. We also obtained the global gene expression patterns of the entire enteroendocrine cell lineage as well as the non-enteroendocrine cell population, comprising enterocytes, goblet cells and Paneth cells. To achieve this, small intestine epithelial cells from male mice resulting from the breeding of Neurogenin3 (Ngn3)-Cre mice with ROSA26-LoxP-STOP-LoxP-tomato indicator mice were isolated based on Tomato fluorescence and negative staining for CD45. Due to the small cell numbers, we constructed each of the three RNA-Seq libraries (GIPGFP, Ngn3TOMATO, and Ngn3-) using a pool of equal amounts of individual RNA samples without RNA amplification.

Transcription profiling of mouse Ngn3 expressing cells and endocrine pancreatic cells from wild type and Ngn3 mutant animals at day 15 of embryonic development

Project description:The basic helix-loop-helix transcription factor Neurogenin3 (Ngn3/Neurog3) is expressed in endocrine progenitor cells in the embryonic mouse pancreas. Ngn3 controls endocrine cell fate decisions. Ngn3 deficient mice do not develop any pancreatic endocrine cells, including insulin producing beta cells, and die postnatally from diabetes. Therefore, the characterization of gene expression in Ngn3-expressing cells and their progeny is of particular interest for the development of novel strategies for cell replacement therapies in type-1 diabetes. Here we describe two studies. In the first study (8 assays) we used mice where the EYFP (Enhanced Yellow fluorescent Protein) is expressed under the control of Ngn3 regulatory elements (knock add on strategy). EYFP-positive, Ngn3-expressing cells, were FACS sorted from embryonic pancreas at day 15.5 (E15.5), as well as EYFP-negative cells. In the second study (6 assays) we compared wild-type and Ngn3 mutant pancreas at E15.5. All samples were hybridized to Affymetrix GeneChip Mouse Genome 430.2.0 array.

Single nucleus multiome (RNAseq and ATACseq) of male mouse pituitary

Project description:We report the single nucleus multiome (RNAseq+ATACseq) of a male mouse pituitary sample. This dataset was generated for supporting the development of a novel computational framework for analyzing gene regulatorty circuitry from single cell multiome datasets. This computational framework extract regulatory circuits consisting of TFs, cis-regulatory sites and target genes by modelling the co-incidence of the RNA levels of the TFs, the chomatin accessibility of the TFs' binding sites and the RNA levels of target genes across single cell. Specifically we identified gonadotrope-specific regulatory circuits under the transcription factor Gata2. These regulatory circuits were validated by male mouse pituitary samples with gonadotrope-conditional knockout of Gata2 previously reported in GSE190066.

Role of Neurogenin3 phosphorylation in the reprogramming of pancreatic organoids into endocrine cells

Project description:During pancreatic development, Neurogenin3 (Ngn3) promotes the differentiation of endocrine cells, including insulin-producing β-cells. Our previous work has shown that Ngn3 phosphorylation on multiple serine-proline (SP) sites increases protein stability and endocrine differentiation (Azzarelli et al., DevCell 2017). Here, we aim to exploit our recent data to investigate whether manipulation of Ngn3 phosphostatus might improve in vitro generation of β-cells for replacement therapies in diabetes. A potential source of β-cells comes from fate conversion of exocrine pancreatic cells into the endocrine lineage, by overexpression of 3 transcription factors, Ngn3, Pdx1 and MafA. Using this approach we show that pancreatic ductal cells grown in vitro as 3D organoids can be reprogrammed to express insulin. The efficiency can be strongly enhanced by substituting wild type Ngn3 with a the un(der)phosphorylated and more active Ngn3 form (6S-A Ngn3). Here we perform transcriptomic analysis of a low number of pancreatic organoid cells expressing wild type or phosphomutant Ngn3, alone or in various combination Pdx1 and/or MafA. The analysis revealed endocrine differentiation and in particular β-like cell gene expression in the conditions where Ngn3 was in combination with both Pdx1 and MafA.
