Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Cardiac disease accounts for the largest proportion of adult mortality and morbidity in the industrialized world. However, progress toward improved clinical treatments is hampered by an incomplete understanding of the genetic programs controlling early cardiogenesis. To better understand this process, we set out to identify genes whose expression is enriched within early cardiac fated populations, obtaining the transcriptional signatures of mouse embryonic stem cells (mESCs) differentiating along a cardiac path.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Mesenchymal populations include a fraction of cells exhibiting multipotency as well as others with limited differentiation range. It has been assumed that the mesenchymal cellular cascade is topped by a multipotent cell, which gives rise to progeny with diminishing differentiation potentials. Here we show that cultured mesenchymal cells, a priori exhibiting a limited differentiation potential, may gain new capacities and become multipotent following single cell isolation. These fate changes were accompanied by up-regulation of differentiation promoting genes, many of which also became H4K20me1 methylated. Early events in the process included TGF and Wnt modulation, and down-regulation of hypoxia signaling. Indeed, hypoxic conditions inhibited the observed cell changes. Overall, cell isolation from neighboring partners caused major molecular changes and particularly, a newly established epigenetic state. It is suggested that MSCs behave non-deterministically and non-hierarchically and should therefore be defined primarily by their capacity to undergo fate changes triggered by environmental cues.

- Affymetrix Human Genome U95 Version 2 Array (hgu95av2)
Description
Rett syndrome (RTT, OMIM #312750) is a severe X-linked neurodevelopmental disorder linked to heterozygous de novo mutations in the MECP2 gene. MECP2 encodes methyl-CpG-binding protein 2 (MeCP2), which represses gene transcription by binding to 5-methylcytosine residues in symmetrically positioned CpG dinucleotides. The disorder is almost exclusively diagnosed in females, because males affected by the disease usually die perinatally due to severe encephalopathy. Direct MeCP2 target genes underlying the neuropathogenesis of RTT remain largely unknown.
Publication Title
FXYD1 is an MeCP2 target gene overexpressed in the brains of Rett syndrome patients and Mecp2-null mice.

Description
Innate lymphoid cells (ILCs) are critical modulators of mucosal immunity, inflammation, and tissue homeostasis, but their full spectrum of cellular states and regulatory landscapes remain elusive. Here, we use a combination of genome-wide RNA-seq, ChIP-seq and ATAC-seq to compare the transcriptional and epigenetic identity of small intestinal ILCs, identifying thousands of distinct gene profiles and regulatory elements. Single-cell RNA-seq, cytometry, and imaging analyses reveal functional compartmentalization of cytokine expression and metabolic activity within the three classical ILC subtypes, and highlight transcriptional states beyond the current canonical classification. In addition, using antibiotic intervention and germ-free mice, we characterize the effect of the microbiome on the ILC regulatory landscape, and determine the response of ILCs to microbial colonization at the single-cell level. Together, our work characterizes the spectrum of transcriptional identities of small intestinal ILCs and describes how ILCs differentially integrate signals from the microbial microenvironment to generate phenotypic and functional plasticity. Overall design: ILC1(CD45+CD3-CD19-GR1-B220-CD127+ROR?t-NkP46+), ILC2(CD45+CD3-CD19-GR1-B220-CD127+ROR?t-KLRG1+) and ILC3(CD45+CD3-CD19-GR1-B220-CD127+ROR?t+) were isolated from small intestine lamina propria of WT C57Bl/6 ROR?t-GFP mice, or antibiotics treated mice (vancomycin, ampicillin,kanamycin, and metronidazole)

Description
The overall goal of our studies is to elucidate the cellular and molecular mechanism by which the transcription factor Casz1 functions in murine heart development. We established that Casz1 is expressed in myocardial progenitor cells beginning at E7.5 and in differentiated cardiomyocytes throughout development. We generated conditional Casz1 knockout mice to show that ablation of CASZ1 in Nkx2.5-positive cardiomyocytes leads to cardiac hypoplasia, ventricular septal defects and lethality by E13.5. To identify the pathways and networks by which Casz1 regulates cardiomyocyte development, we used RNA-Seq and identified genes involved in cell proliferation are upregulated in Casz1 mutants compared to wild-type littermates. We conclude that Casz1 is essential for cardiac development and has a pivotal role in regulating part of the cardiac transcriptional program. Overall design: 3 biological replicates of the two genotypes (Nkx2-5+/+,Casz1f/+ and Nkx2-5Cre/+,Casz1f/f) were used for RNA-seq to determine genes that are differentially expressed in the murine heart when Casz1 is mutated. Nkx2-5+/+,Casz1f/+ were used as wild-type controls for comparison.
Publication Title
Casz1 is required for cardiomyocyte G1-to-S phase progression during mammalian cardiac development.
