(Submitter supplied) Recent sequencing efforts have failed to identify consistent oncogenic driver mutations in most adult soft tissue sarcomas. Therefore, we investigated alternate genetic/epigenetic mechanisms underlying sarcomagenesis to facilitate development of novel therapeutics. Our previous work showed that deregulation of the Hippo pathway increases proliferation in many types of sarcoma. We have now identified the mechanism of Hippo-mediated sarcomagenesis using autochthonous mouse models, ChIP-seq (H3K27Ac) and super-enhancer (SE) analysis of human undifferentiated pleomorphic sarcoma (UPS), an aggressive muscle-derived tumor. more...

(Submitter supplied) The Hippo pathway effector YAP1 controls stem cell fate in epithelial tissues, but its role in stem cells of non-epithelial tissues, such as skeletal muscle, is poorly documented. Here we show that sustained YAP1 activity in mouse activated satellite cells in vivo induces rhabdomyosarcoma (RMS) resembling human embryonal RMS (ERMS) with high penetrance and short latency. The transcriptional program of YAP1 in ERMS drives pro-proliferative pathways whilst decreasing MyoD1 and MEF2 pro-differentiation activity to globally maintain the myoblastic phenotype of ERMS. more...

(Submitter supplied) Doxycycline-inducible YAP1 S127A-driven rhabdomyosarcoma (RMS) tumors, control skeletal muscle and regressed tumors following YAP1 normalization by doxycycline withdrawal were compared to determine the YAP1-regulated gene expression profile relevant to RMS formation. To characterize the role of YAP1 in embryonal RMS at the molecular level and identify a gene signature for YAP1 activity readout, we compared the gene expression profiles of our YAP1-driven ERMS with control donor skeletal muscle (SKM) and doxycycline-withdrawn regressing tumors by microarray (doxycycline withdrawal for 3 or 6 days; OFF3 and OFF6, respectively). more...

(Submitter supplied) This work examines sarcoma formation within discrete subsets of KRAS(G12V)-expressing p16p19null myogenic and mesenchymal cells found normally in skeletal muscle. We show that prospectively isolated skeletal muscle precursor cells (SMPs) within the satellite cell pool can serve as cancer cells-of-origin for mouse rhabdomyosarcomas (soft tissue sarcomas with features of myogenic differentiation). Alternatively, non-myogenic progenitors (ScaPCs) induce sarcomas lacking myogenic differentiation markers.

(Submitter supplied) The bromodomain and extra-terminal domain inhibitors (BETi) are promising epigenetic drugs for the treatment of various cancers through suppression of oncogenic transcription factors including MYC. However, only a subset of CRC cells response to BETi, suggesting an intrinsic resistance to BETi in CRC. We investigated the effect of JQ1 on cell proliferation, apoptosis, angiogenesis and MYC expression in a panel of 11 CRC cells in vitro and in vivo. more...

(Submitter supplied) Regulation of organ size is important for development and tissue homeostasis. In Drosophila, Hippo signaling controls organ size by regulating the activity of a TEAD transcription factor, Scalloped, through modulation of its coactivator protein Yki. The role of mammalian Tead proteins in growth regulation, however, remains unknown. Here we examined the role of mouse Tead proteins in growth regulation. more...

(Submitter supplied) Sarcomas are rare, difficult to treat, mesenchymal lineage tumours that disproportionately affect children and young adults. Immunologically-based therapies have improved outcomes for numerous adult cancers, however, such approaches have proven ineffective for the majority of individuals with advanced sarcomas. Clinically relevant, immunologically-competent, and transplantable pre-clinical sarcoma models are needed in order to test and develop novel immunologically-based therapies for sarcoma. more...

(Submitter supplied) Ewing sarcomas (ES) are highly malignant, osteolytic bone or soft tissue tumors, which are characterized by early metastasis into lung and bone. Genetically, ES are defined by balanced chromosomal EWS/ETS translocations, which give rise to chimeric proteins (EWS-ETS) that generate an oncogenic transcriptional program associated with altered epigenetic marks throughout the genome. By use of an inhibitor (JQ1) blocking BET bromodomain binding proteins (BRDs) we strikingly observed a strong down-regulation of the predominant EWS-ETS protein EWS/FLI1 in a dose dependent manner. more...

(Submitter supplied) Purpose: In this study we employed unbiased, genome-wide techniques to investigate how inflammation-induced NF-kB activation by acute (LPS vs. saline) and chronic (high-fat diet vs. regular chow) environmental stimuli leads to circadian disruption. Methods: We performed ChIP-seq with antibodies directed against the p65 subunit of NF-kB, CLOCK, BMAL1, H3K27Ac and RNA Poll II in livers from mice treated with LPS or saline. more...

(Submitter supplied) To investigate the role of p53 and DICER in the induction of ER stress, wildtype, p53 knockout or DICER mutant HCT116 colon cancer cells were treated with the ER stress inducers tunicamycin or brefeldin A for 24 hours. Microarray analysis was used to determine changes in gene expression associated with the induction of ER stress, and to compare this induction in wildtype, p53 knockout or DICER mutant HCT116 colon cancer cells

(Submitter supplied) Loss of Traf3 caused a dramatic induction of innate immune response genes. Antigen presentation, interferon response genes and genes responsible for foreign DNA and RNA recognition were strongly upregulated by deletion of Traf3, but KO of p100 in Traf3 KO samples reversed the activation of these pathways. We did not detect any stimulation by Traf3 KO of those signaling pathways classically involved in proliferation, including PI3K/AKT, JNK, TGF-beta, WNT and Hippo

(Submitter supplied) Recent reports indicate hypoxia influences the clock through the transcriptional activities of hypoxia inducible factors (HIFs) at clock genes. Unexpectedly, we uncover a profound disruption of the circadian clock and diurnal transcriptome when hypoxic cells are permitted to acidify, recapitulating the tumor microenvironment. Buffering against acidification or inhibiting lactic acid production fully rescues circadian oscillation. more...

(Submitter supplied) While Yap1, a Hippo pathway transcriptional effector, plays numerous roles in development and cancer, its functions in embryonic stem (ES) cell differentiation remain poorly characterized. It is known that approximately 30% of ES cells die after exiting self-renewal to differentiate, but upstream regulators of this process are not well known. We first observe that ES cells lacking Yap1 experience massive cell death upon the exit from self-renewal. more...

(Submitter supplied) Aberrant NF-kB signaling fuels tumor growth in multiple human cancer types including both hematologic and solid malignancies. Chronic elevated alternative NF-kB signaling can be modeled in transgenic mice upon activation of a conditional NF-kB-inducing kinase (NIK) allele lacking the regulatory TRAF3 binding domain (NT3). Here, we report that expression of NT3 in the mesenchymal lineage with Osterix (Osx/Sp7)-Cre or Fibroblast Specific Protein (Fsp1)-Cre caused subcutaneous, soft tissue tumors. more...

(Submitter supplied) Studies from global loss-of-function mutants suggest that alternative NF-kB downstream of NF-kB inducing kinase (NIK) is a cell-intrinsic negative regulator of osteogenesis. However, the interpretation of the osteoblast and/or osteocyte contribution to the bone phenotype is complicated by simultaneous osteoclast defects in these models. Therefore, we turned to a transgenic mouse model to investigate the direct role of NIK in the osteolineage. more...
