Thus, the strongly enhanced and sustained resistant to diet-induced obesity. This is due, in part, to enhanced cAMP response previously observed in FOXC2 transgenic catecholamine-induced cAMP-PKA signaling in FOXC2 trans- adipocytes is most likely a result of the increased expression genic mice. Here we show that rolipram treatment of adipocytes of b-AR receptors, since this would lead to a more profound from FOXC2 transgenic mice did not increase isoproterenol-in- activation of b-AR associated adenylyl cyclases (ACs) and, duced cAMP accumulation to the same extent as in wild type thus, increased generation of cAMP from ATP. -

Received: 24 November 2011; in revised form: 18 January 2012 / Accepted: 19 January 2012 / Published: 6 February 2012 Abstract: Phosphodiesterase 10A (PDE10A) is a key enzyme of intracellular signal transduction which is involved in the regulation of neurotransmission. The molecular imaging of PDE10A by PET is expected to allow a better understanding of physiological and pathological processes related to PDE10A expression and function in the brain. The aim of this study was to develop a new 18F-labeled PDE10A ligand based on a 6,7-dimethoxy- 4-pyrrolidinylquinazoline and to evaluate its properties in biodistribution studies. -

Peripheral Blood Gene Expression Patterns Discriminate Among
Mesko et al. BMC Medical Genomics 2010, 3:15 http://www.biomedcentral.com/1755-8794/3/15 RESEARCH ARTICLE Open Access PeripheralResearch article blood gene expression patterns discriminate among chronic inflammatory diseases and healthy controls and identify novel targets Bertalan Mesko†1, Szilard Poliska1†1,4, Andrea Szegedi3, Zoltan Szekanecz5, Karoly Palatka6, Maria Papp6 and Laszlo Nagy*1,2,4 Abstract Background: Chronic inflammatory diseases including inflammatory bowel disease (IBD; Crohn's disease and ulcerative colitis), psoriasis and rheumatoid arthritis (RA) afflict millions of people worldwide, but their pathogenesis is still not well understood. It is also not well known if distinct changes in gene expression characterize these diseases and if these patterns can discriminate between diseased and control patients and/or stratify the disease. The main focus of our work was the identification of novel markers that overlap among the 3 diseases or discriminate them from each other. Methods: Diseased (n = 13, n = 15 and n = 12 in IBD, psoriasis and RA respectively) and healthy patients (n = 18) were recruited based on strict inclusion and exclusion criteria; peripheral blood samples were collected by clinicians (30 ml) in Venous Blood Vacuum Collection Tubes containing EDTA and peripheral blood mononuclear cells were separated by Ficoll gradient centrifugation. RNA was extracted using Trizol reagent. Gene expression data was obtained using TaqMan Low Density Array (TLDA) containing 96 genes that were selected by an algorithm and the statistical analyses were performed in Prism by using non-parametric Mann-Whitney U test (P-values < 0.05). Results: Here we show that using a panel of 96 disease associated genes and measuring mRNA expression levels in peripheral blood derived mononuclear cells; we could identify disease-specific gene panels that separate each disease from healthy controls. -
