Hippo signaling instructs ectopic but not normal organ growth [Liver YapHyper]

ABSTRACT: We conditionally activated Yap in hepatocytes of adult mice by two different methods: we deleted the Lats1/2 kinases via injecting AAV8-Cre into Lats1/2 double floxed mice (Lats1/2 KO) and we overexpressed YAP via doxycycline feeding of mice that expressed the tetracycline-activated transactivator (rtTA) under the hepatocyte-specific ApoE promoter and human YAP from a rtTA-responsive TetO promoter (Apo>YAP).

Gene expression changes caused by YAP overexpression and Nf2 deletion in the developing mouse brain

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.

Effect of Misexpression of Sox9 on Gastric Differentiation

Project description:To determine if Sox9 was sufficient to drive mucous differentiation in the gastric epithelium, we bred mice carrying alleles for ROSA26rtTA.IRES.EGFP, TetO-Sox9, and Fgf20Cre.GFP. In these mice, cells expressing Cre will induce rtTA from the ROSA26rtTA.IRES.EGFP allele. To explore transcriptional changes following adult misexpression of Sox9, we isolated RNA from the corpus of Fgf20Cre.GFP/Cre.GFP; ROSA26rtTA.IRES.EGFP/rtTA.IRES.EGFP; TetO-Sox9 pup (misexpression animals) and ROSA26rtTA.IRES.EGFP/rtTA.IRES.EGFP; TetO-Sox9 pup (control) animals and performed RNA-sequencing.

Transcription profiling by array of human MCF10A cells expressing YAP to identify the targets of the YAP oncogene

Project description:YAP is an oncogene and an inducer of Epithelial-to-Mesenchymal Transition (EMT). We used microarrays to detail the global program of gene expression to identify YAP target genes. PUBLICATION ABSTRACT:; The Hippo pathway defines a novel signaling cascade regulating cell proliferation and survival in Drosophila, which involves the negative regulation of the transcriptional coactivator Yorkie by the kinases Hippo and Warts. We have recently shown that the human ortholog of Yorkie, YAP, maps to a minimal amplification locus in mouse and human cancers, and that it mediates dramatic transforming activity in MCF10A primary mammary epithelial cells. Here we show that LATS proteins (mammalian orthologs of Warts) interact directly with YAP in mammalian cells and that ectopic expression of LATS1, but not LATS2, effectively suppresses the YAP phenotypes. Furthermore, shRNA-mediated knockdown of LATS1 phenocopies YAP overexpression. Since this effect can be suppressed by simultaneous YAP knockdown, it suggests that YAP is the primary target of LATS1 in mammalian cells. Expression profiling of genes induced by ectopic expression of YAP or by knockdown of LATS1 reveals a subset of potential Hippo pathway targets implicated in epithelial-to-mesenchymal transition (EMT), suggesting that this is a key feature of YAP signaling in mammalian cells. Experiment Overall Design: MCF10A cells were infected with retrovirus constructs (vector or YAP) and puromycin was used to select for transduced cells. Cells were split and grown to ~60-75%% confluency at which point they were harvested for RNA. Vector vs. YAP comparison was done in duplicate.

Splicing Factor SRSF1 Deficiency in the Liver Triggers NASH-like Pathology via R-Loop Induced DNA Damage and Cell Death

Project description:Regulation of RNA processing contributes profoundly to tissue development and physiology. The serine-arginine-rich splicing factor 1 (SRSF1) is essential for hepatocyte function and survival. Although SRSF1 is mainly known for its many roles in mRNA metabolism, it is also crucial for maintaining genome stability. We show that acute liver damage in the setting of targeted SRSF1 deletion in mice is primarily mediated by the excessive formation of deleterious RNA–DNA hybrids (R-loops), which induce DNA damage. Combining hepatocyte-specific transcriptome, proteome, and RNA binding analyses, we demonstrate that widespread genotoxic stress following SRSF1 depletion results in global inhibition of mRNA transcription and protein synthesis, leading to impaired metabolism and trafficking of lipids. Accumulation of lipids in SRSF1-deficient hepatocytes is quickly followed by necroptotic cell death, inflammation, and fibrosis, resulting in NASH-like liver pathology. This pathogenesis is recapitulated in SRSF1-depleted human liver cancer cells illustrating a conserved and fundamental role for SRSF1 in preserving genome integrity and tissue homeostasis. This data set contains a proteomic comparison of hepatocytes from wild type vs. acute knockout of SRSF1. The acute knockout was generated by injecting 8-week-old SRSF1 fl/fl mice with a viral vector expressing Cre under the control of the liver-specific thyroxine binding globulin (TBG) promoter (AAV8-TBG-iCre). Controls were generated by injecting AAV8-TBG-GFP viral vector. The hepatocytes were isolated 2 weeks post injection.

Expression data of mouse mucinous lung tumors

Project description:Transgenic mice (Scgb1a1-rtTA/[tetO]-KRAS.G12D/Nkx2-1+/-) develop mucinous lung tumors. Gene expression analysis was performed using mRNAs from the whole lungs of the mice compared to that of the control mice. We used microarrays to detail the global program of gene expression underlying development of mucinous lung tumors and identified distinct classes of up-regulated genes during this process. mRNAs were isolated from the whole lungs of the transgenic mice (Scgb1a1-rtTA/[tetO]-KRAS.G12D/Nkx2-1+/-) after 2 months doxycycline administration and hybridized on Affymetrix microarrays. We sought to identify genes induced in mucinous lung tumors.
