Epigenetic regulator function through mouse gastrulation

ABSTRACT: Development of a multicellular organism uses the same genetic code to generate a broad diversity of cell types, which is instructed by extracellular cues and orchestrated by transcriptional activators and repressors. While transcription factors establish cell identities according to the central dogma, a number of enzymes, which index and regulate chromatin, appear to perform essential functions as well. We optimized a versatile experimental and analytical approach that allows for rapid perturbation of genes and the recovery of high replicate powered phenotypic information. We applied this set-up to investigate a panel of epigenetic regulators that are essential for early gestation. Our comparative analysis approach enabled us to pinpoint affected genetic pathways and cell lineage-specific effects that distinguish even closely related regulators, such as polycomb repressive complexes 1 and 2 (PRC1 and PRC2). Moreover, by incorporating additional epigenetic data, we were able to identify early aberrations that partially explain how certain developmental abnormalities emerge at the onset of gastrulation.

Leveraging the Mendelian Disorders of the Epigenetic Machinery to Systematically Map Functional Epigenetic Variation - RNA-seq

Project description:The Mendelian Disorders of the Epigenetic Machinery (MDEMs) have emerged as a class of Mendelian disorders caused by loss-of-function variants in epigenetic regulators. Although each MDEM has a different causative gene, they exhibit several overlapping disease manifestations. Here, we hypothesize that this phenotypic convergence is a consequence of common abnormalities at the epigenomic level, which directly or indirectly lead to downstream convergence at the transcriptomic level. This implies that identifying abnormalities shared across multiple MDEMs could pinpoint locations where epigenetic variation is causally related to disease phenotypes. To test our hypothesis, we perform a comprehensive interrogation of chromatin (ATAC-Seq) and expression (RNA-Seq) states in B cells from mouse models of three MDEMs (Kabuki types 1&2 and Rubinstein-Taybi syndromes). We build on recent work in covariate-powered multiple testing to develop a new approach for the overlap analysis, which enables us to find extensive overlap primarily localized in gene promoters. We show that disruption of chromatin accessibility at promoters often leads to disruption of downstream gene expression, and identify a total of 463 loci and 249 genes commonly disrupted across the three MDEMs. As an example of how widespread dysregulation leads to specific phenotypes, we show that subtle expression alterations of multiple, directly relevant genes, collectively contribute to IgA deficiency in KS1 and RT. In contrast, we predict that KS2 does not have IgA deficiency, and confirm this pattern in mice. We propose that the joint study of MDEMs offers a principled approach for systematically mapping functional epigenetic variation in mammals.

Enhancer-instructed chromatin folding and compartmentalization dictate Vκ repertoire rearrangement to combat bacterial infection [CUT&RUN]

Project description:Antigen receptor loci are organized into variable (V), diversity (D), and joining (J) elements that rearrange to generate diverse antigen receptor repertoires. Here, we identified an enhancer (E34) in the immunoglobulin kappa locus (Igκ) that instructed rearrangement of Vκ genes located in a sub-topologically associating domain (subTAD), including a Vκ gene encoding for antibodies targeting bacterial phosphorylcholine. E34 promoted the deposition of active histone marks across the E34 subTAD to instruct its nuclear repositioning from a V(D)J recombination-repressive compartment to a permissive one. E34-induced nuclear repositioning of the E34 subTAD promoted Vκ-Jκ interactions assisted by enhancer-associated epigenetic marks and de novo CTCF binding. Finally, we found that E34-instructed Vκ-Jκ rearrangement was essential to combat Streptococcus pneumoniae but not methicillin-resistant Staphylococcus aureus or influenza infections. These data show how enhancer-instructed chromatin topology mechanically pulls specific Vκ and Jκ genes into close physical proximity to generate distinct antibody repertoires to combat bacterial infection.

Construction of multilayered small intestine-like tissue by reproducing interstitial flow

Project description:Recent advances have made modeling human small intestines in vitro possible, but it remains a challenge to recapitulate fully their structural and functional characteristics. We suspected interstitial flow within the intestine, powered by circulating blood plasma during embryonic organogenesis, to be a vital factor. We aimed to construct an in vivo-like multilayered small intestinal tissue by incorporating interstitial flow into the system and, in turn, developed the micro-small intestine systems by differentiating definitive endoderm and mesoderm cells from human pluripotent stem cells simultaneously on a microfluidic device capable of replicating interstitial flow. This approach enhanced cell maturation and led to the development of a three-dimensional small intestine-like tissue with villi-like epithelium and an aligned mesenchymal layer. Our micro-small intestine system not only overcomes the limitations of conventional intestine models but also offers a unique opportunity to gain insights into the detailed mechanisms underlying intestinal tissue development.

ATAC-seq of gata5GFP+/- cells in WT and Gata5/6 deficient zebrafish embryos during gastrulation

Project description:Gata5/6 are essential regulators in zebrafish heart development. To understand how Gata5/6 affects the chromatin accessibility and regulates cardiac gene expression, we FACS-isolated GFP+ and GFP- cells from Tg(gata5:GFP) transgenic embryos in both control and Gata5/6 deficient embryos (injected with Gata5/6 morpholinos) and conducted ATAC-seq. We performed the experiments at 8 hours post fertilization, intending to dissect the role of Gata5/6 in the earliest step in cardiac lineage specification. We did 2-3 biological replicates for each sample. ATAC-seq libraries were made using previously published protocol (Buenrostro et al., Nat. Methods, 2013. DOI: 10.1038/nmeth.2688) and sequenced on Illumina Hiseq2500.
