August 2014 Diese Dissertation ist auf den Internetseiten der Hochschulbibliothek online verfugbar.¨ Zusammenfassung Krebserkrankungen stellen weltweit eine der h¨aufigsten Todesursachen dar. Aus diesem Grund ist die Aufkl¨arung der zugrunde liegenden Mechanismen und Ur- sachen ein essentielles Ziel der molekularen Onkologie. Die Tumorforschung der letzten Jahre hat gezeigt, dass die Entstehung solider Karzinome ein Mehrstufen- Prozess ist, bei dem neben Onkogenen auch Tumorsuppresorgene eine entschei- dende Rolle spielen. Viele der heute bekannten Gene des WNT-Signalweges wur- den bereits als Onkogene oder Tumorsuppressorgene charakterisiert. Eine Dere- gulation des WNT-Signalweges wird daher mit der Entstehung und Progression vieler humaner Tumorentit¨aten wie beispielsweise auch dem Mammakarzinom, der weltweit h¨aufigsten Krebserkrankung der Frau, assoziiert. SFRP1, ein nega- tiver Regulator der WNT-Signalkaskade, wird in Brusttumoren haupts¨achlich durch den epigenetischen Mechanismus der Promotorhypermethylierung -

Transcriptomes and Neurotransmitter Profiles of Classes of Gustatory And
ARTICLE DOI: 10.1038/s41467-017-01095-1 OPEN Transcriptomes and neurotransmitter profiles of classes of gustatory and somatosensory neurons in the geniculate ganglion Gennady Dvoryanchikov 1, Damian Hernandez1, Jennifer K. Roebber 2, David L. Hill3, Stephen D. Roper 1,2,4 & Nirupa Chaudhari 1,2,4 Taste buds are innervated by neurons whose cell bodies reside in cranial sensory ganglia. Studies on the functional properties and connectivity of these neurons are hindered by the lack of markers to define their molecular identities and classes. The mouse geniculate ganglion contains chemosensory neurons innervating lingual and palatal taste buds and somatosensory neurons innervating the pinna. Here, we report single cell RNA sequencing of geniculate ganglion neurons. Using unbiased transcriptome analyses, we show a pronounced separation between two major clusters which, by anterograde labeling, correspond to gus- tatory and somatosensory neurons. Among the gustatory neurons, three subclusters are present, each with its own complement of transcription factors and neurotransmitter response profiles. The smallest subcluster expresses both gustatory- and mechanosensory- related genes, suggesting a novel type of sensory neuron. We identify several markers to help dissect the functional distinctions among gustatory neurons and address questions regarding target interactions and taste coding. 1 Department of Physiology & Biophysics, University of Miami Miller School of Medicine, Miami, FL 33136, USA. 2 Graduate Program in Neurosciences, University of Miami Miller School of Medicine, Miami, FL 33136, USA. 3 Department of Psychology, University of Virginia, Charlottesville, VA 22904, USA. 4 Department of Otolaryngology, University of Miami Miller School of Medicine, Miami, FL 33136, USA.

Co-Stimulation of Purinergic P2X4 and Prostanoid EP3 Receptors Triggers Synergistic Degranulation in Murine Mast Cells
International Journal of Molecular Sciences Article Co-Stimulation of Purinergic P2X4 and Prostanoid EP3 Receptors Triggers Synergistic Degranulation in Murine Mast Cells Kazuki Yoshida 1, Makoto Tajima 1, Tomoki Nagano 1, Kosuke Obayashi 1, Masaaki Ito 1, Kimiko Yamamoto 2 and Isao Matsuoka 1,* 1 Laboratory of Pharmacology, Faculty of Pharmacy, Takasaki University of Health and Welfare, Takasaki-shi, Gunma 370-0033, Japan; [email protected] (K.Y.); [email protected] (M.T.); [email protected] (T.N.); [email protected] (K.O.); [email protected] (M.I.) 2 Department of Biomedical Engineering, Graduate School of Medicine, The University of Tokyo, Tokyo 113-0033, Japan; [email protected] * Correspondence: [email protected]; Tel.: +81-27-352-1180 Received: 4 October 2019; Accepted: 16 October 2019; Published: 17 October 2019 Abstract: Mast cells (MCs) recognize antigens (Ag) via IgE-bound high affinity IgE receptors (Fc"RI) and trigger type I allergic reactions. Fc"RI-mediated MC activation is regulated by various G protein-coupled receptor (GPCR) agonists. We recently reported that ionotropic P2X4 receptor (P2X4R) stimulation enhanced Fc"RI-mediated degranulation. Since MCs are involved in Ag-independent hypersensitivity, we investigated whether co-stimulation with ATP and GPCR agonists in the absence of Ag affects MC degranulation. Prostaglandin E2 (PGE2) induced synergistic degranulation when bone marrow-derived MCs (BMMCs) were co-stimulated with ATP, while pharmacological analyses revealed that the effects of PGE2 and ATP were mediated by EP3 and P2X4R, respectively. Consistently, this response was absent in BMMCs prepared from P2X4R-deficient mice. -
