Project description:To investigate the roles of YAP in the submandibular gland (SMG) epithelium, we compared the gene expression profiles of E15.5 SMGs isolated from Yap-loxP/loxP or Yap-loxP/loxP;Shh-Cre (i.e. Cre recombinase from the Shh promoter) embryos.

Project description: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 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.

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.

Project description:Microarray analyses with cells/tissues overexpressing YAP have revealed many transcription targets of YAP (Dong et al, 2007; Zhao et al, 2008). However, as YAP induces transformation of non-cancerous cells, we thought many of known targets of YAP may be indirect consequence of transforming property of YAP. To identify the immediate transcription targets for YAP, we utilized immortalized mammary epithelial MCF-10A cells expressing a tamoxifen inducible, hyperactive (S127/381A) YAP mutant (MCF-10A ERT2-YAP 2SA). MCF-10A ERT2 and MCF-10A ERT2-YAP 2SA are generated. Each cell line was treated with 0.1% of ethanol (solvent) or 1uM of 4-hydroxytamoxifen for 2 or 6 hours. This makes 6 samples per set. The experiments were done in duplicate. The expression data from MCF-10A ERT2 and MCF-10A ERT2-YAP 2SA before tamoxifen treatment can serve as control.

Project description:The transcriptional coactivator YAP is the key downstream effector of the Hippo pathway. YAP overexpression in the developing mouse brain results in excessive expansion of the neural progenitor pool and severe perturbation of brain development. Nf2/Merlin is a tumor suppressor whose mutations are found in many human cancers. Loss of Merlin during brain development causes overexpansion of the neural progenitor pool. We used microarrays to identify the gene expression changes caused by YAP overexpression and Nf2 deletion. We used a double-transgenic system to overexpress YAP in the developing mouse brain by crossing mice carrying a doxycycline-dependent allele of YAP1-S127A (TetO-YAP1) with those expressing the reverse tetracycline-dependent transactivator rtTA under the control of the neural progenitor-specific Nestin promoter (Nes-rtTA) and feeding the dam with doxycycline-containing food (200 mg/kg) from E7.5. We conditionally deleted Nf2 using the telencephalon-specific Emx1-Cre.

Project description:Inadequate adaption to mechanical forces, including an elevated blood pressure, contributes to the development of arterial aneurysms. Recent studies have pointed to a mechano-protective role of YAP and TAZ in vascular smooth muscle cells (SMCs). Here, we created vascular SMC-specific knockouts (KOs) of YAP and TAZ using integrin-alpha8-Cre mice (i8-YT-KO). I8-YT-KO mice spontaneously developed aneurysms in the abdominal aorta within two weeks of knockout induction. Loss of YAP expression was also observed in human aortic aneurysms. I8-YT-KO mice developed vascular lesions in other arteries at later times, but the gastrointestinal tract was spared. Aneurysms were characterized by elastin disarray, SMC apoptosis, and accumulation of proteoglycans and inflammatory cells, including macrophages and neutrophils. RNA-sequencing, proteomics, and myography demonstrated decreased contractile differentiation of SMCs and impaired vascular contractility. This associated with partial loss of vascular myocardin expression, reduced blood pressure, and edema. Mediators in the cGAS-STING pathway, which sparks inflammation in response to double-stranded DNA, were increased in aortic lysates. A sizeable increase of the transcription factor Sox9, along with several direct target genes, including aggrecan (Acan), contributed to proteoglycan accumulation. This was the earliest detectable change, occurring three days after knockout induction, and before the pro-inflammatory transition. In conclusion, Itga8-Cre deletion of YAP and TAZ represents a rapid and spontaneous aneurysm model that re-capitulates features of human abdominal aortic aneurysms.

Project description:Regulatory T cells (Tregs) are critical for maintaining self-tolerance and immune homeostasis, but their suppressive function can impede effective anti-tumor immune responses. Foxp3 is a transcription factor expressed in Tregs that is required for their function. The pathways and microenvironmental cues governing Foxp3 expression and Treg function are not completely understood. We found that Yes-associated protein (YAP), a co-activator of the Hippo pathway, is highly expressed in Tregs and bolsters Foxp3 expression and Treg function in vitro and in vivo. To assess how YAP influences patterns of gene expression in Tregs, naïve CD4+ T cells and Tregs were isolated from wild type mice and CD4+ T cell lineage-restricted YAP knockout mice (YAPflox/flox, CD4-Cre+). Gene expression by naïve CD4+ T cells and their resting and stimulated Treg counterparts was analyzed by RNASeq. Our findings reveal that YAP ablation undermines expression of multiple genes involved in the TGFβ/SMAD signaling pathway in Tregs including Activin. These findings suggest that YAP potentiates activity along a pro-Treg signaling axis.
