Expression data from Ezh2 epithelial knock-out mouse lungs at E14.5

ABSTRACT: Ezh2 epigenetically suppresses developmentally-regulated genes. Ezh2 is highly expressed during development, including in the lung. We knocked out Ezh2 in the developing lung epithelium using a Shh-cre driver which is active in foregut endoderm prior to lung morphogenesis. Many developmentally regulated genes became derepressed in the mutant lungs, leading to defects in lung development. Microarray analysis of genes upregulated in Ezh2 epithelial knock-out mouse lungs compared to Shh-cre controls.

We knocked out Ezh2 in the developing lung epithelium using a Shh-cre driver which is active in foregut endoderm prior to lung morphogenesis. Many developmentally regulated genes became derepressed in the mutant lungs, leading to defects in lung development. Microarray analysis of genes upregulated in Ezh2 epithelial knock-out mouse lungs compared to Shh-cre controls. We generated Ezh2 epithelial mutant lungs by crossing the Ezh2-floxed line (Su et al., 2003) with the Shh-cre line (Harfe et al., 2004). We isolated RNA from whole mouse lungs at embryonic day 14.5 from 4 Shh-cre:Ezh2-flox/flox embryos (M1-M4) and 4 Shh-cre embryos (C1-C4). Littermates are as follows: C1+C2; C3+C4; M1+M2; M3+M4.

Investigation of the gene expression changes triggered by the lung mesenchymal Tsc2KO in each major cell subpopulation of the adult mouse lung

Project description:Tumor suppressor Tuberous sclerosis complex 2 (TSC2) is a key negative regulator of mammalian target of rapamycin (mTOR), a central controller of cell growth and metabolism in health and disease. Loss of TSC2 induces the constitutive activation of mTORC1 in rare lung disease pulmonary Lymphangioleiomyomatosis (LAM), which affects only women of childbearing age and characterized by lung destruction and progressive loss of pulmonary function. Little is known how TSC2 loss induces LAM and what is the LAM cell of origin. To determine cell-type specific effects of TSC2 loss and mTORC1 activation on lung homeostasis we generated new transgenic mice with targeted Tsc2 deletion in lung mesenchyme Tbx4-Cre+Tsc2flox/flox and lung epithelium Shh-Cre+Tsc2flox/flox. Both Tbx4-Cre+, Tsc2flox/flox and Shh-Cre+, Tsc2flox/flox mice were viable and fertile. Adult Tbx4-Cre+Tsc2flox/flox mice demonstrated mTORC1 activation in lung mesenchyme, progressive alveolar enlargement, female-specific pulmonary function decline and prgenancy-induced lesion growth. To investigate molecular mechanism underlying observed phenotypic changes in the Tsc2KO lungs we performed comparative bulk-RNAseq analysis of the gene expression changes in the major cell subpopulations of the adult female 8-week-old Tsc2KO mouse lungs compared to the age- and sex-matched WT controls.

Whole lung transcriptome from lung epithelial IRE1α knockout mice

Project description:This experiment sought to characterize the whole lung transcriptional changes induced by loss of IRE1a function in the lung epithelium. Mice were Shh(Cre/+) IRE1a(fl/fl) on the C57BL/6 background, and had loss of IRE1a function in the epithelium based on XBP1 splicing activity. Lungs from uninjured mice were harvested, flash-frozen, homogenized, and RNA isolated by Trizol extraction.

The role of Foxp1/4 in lung development

Project description:Foxp1/4 transcription factors are conserved transcriptional repressors expressed in overlapping patterns during lung development as well as in the adult lung. However, the role of Foxp1/4 in development and homeostasis of the pseudostratified epithelium of the proximal airways and trachea is unknown. We propose to determine the roles for Foxp1/4 in lung development by deleting these genes in lung epithelial specific knockout mice. To explore the genome wide consequences of Foxp1/4 deficiency on secretory epithelial differentiation in the lung, we performed microarray analysis of Shh- cre control and Foxp1/4ShhcreDKO mutants lungs at E14.5, 3 embryos, respectively.

Sin3a regulates epithelial progenitor cell fate during lung development

RNA-seq expression profiling of Grhl2-deficient and control murine lung epithelium at embryonic day E16.5

Project description:Epithelial (CD31-CD45-EpCAM+) cells were isolated by FACS from Grhl2-deficient (Shh-Cre;Grhl2f/-) and control (Shh-Cre;Grhl2f/+) embryonic lungs at day E16.5 (3 biological replicates/genotype). Total RNA extracted from the samples was subjected to next-generation sequencing (NGS) library preparation using standard Illumina protocols. Completed libraries from individual samples were sequenced on a HiSeq2500 at the Australian Genome Research Facility.

Repression of Igf1 expression by Ezh2 prevents basal cell differentiation in the developing lung

Project description:Gene expression (RNA-seq) and H3K27me3 binding (ChIP-seq) profiling of wild type and Ezh2-deficient mouse lung epithelium. Lungs from wild type and Ezh2-deficient mice (Ezh2 deletion is specific to lung epithelium) were collected at day e16.5. Lung cells were separated into epithelial and stromal populations based on EpCAM expression. Epithelial cells were profiled for both gene expression (Total RNA-seq) and H3K27me3 binding (ChIP-seq). Additionally, stromal cells were also profiled for gene expression.

TIM-3 on myeloid cells promotes pulmonary inflammation through increased production of galectin-3

Project description:T cell immunoglobulin and mucin-containing molecule 3 (TIM-3) exhibits unique, cell type- and context-dependent characteristics and functions. Here, we report that TIM-3 on myeloid cells plays essential roles in modulating lung inflammation. We found that myeloid cell-specific TIM-3 knock-in (FSF-TIM3/LysM-Cre+) mice have lower body weight and shorter lifespan than WT mice. Intriguingly, the lungs of FSF-TIM3/LysM-Cre+ mice display excessive inflammation and features of disease-associated pathology. We further revealed that galectin-3 levels are notably elevated in TIM-3-overexpressing lung-derived myeloid cells. Furthermore, both TIM-3 blockade and GB1107, a galectin-3 inhibitor, ameliorated lung inflammation in FSF-TIM3/LysM-Cre+/- mice. Using an LPS-induced lung inflammation model with myeloid cell-specific TIM-3 knock-out mice, we demonstrated the association of TIM-3 with both lung inflammation and galectin-3. Collectively, our findings suggest that myeloid TIM-3 is an important regulator in the lungs and that modulation of TIM-3 and galectin-3 could offer therapeutic benefits for inflammation-associated lung diseases.

Characterization of the mid-foregut transcriptome identifies genes regulated during lung bud induction.

Project description:To identify genes expressed during initiation of lung organogenesis, we generated transcriptional profiles of the prospective lung region of the mouse foregut (mid-foregut) microdissected from embryos at three developmental stages between embryonic day 8.5 (E8.5) and E9.5. This period spans from lung specification of foregut cells to the emergence of the primary lung buds. We identified a number of known and novel genes that are temporally regulated as the lung bud forms. Genes that regulate transcription, including DNA binding factors, co-factors, and chromatin remodeling genes, are the main functional groups that change during lung bud formation. Members of key developmental transcription and growth factor families, not previously described to participate in lung organogenesis, are expressed in the mid-foregut during lung bud induction. These studies also show early expression in the mid-foregut of genes that participate in later stages of lung development. This characterization of the mid-foregut transcriptome provides new insights into molecular events leading to lung organogenesis. Three samples (developmental stages), three biological replicates (5-10 pooled mid-foreguts)
