To address this issue, we sequenced the OR repertoire in 332 individuals and examined the relationship between genetic variation and 276 olfactory phenotypes, including the perceived intensity and pleasantness of 68 odorants at two concentrations, detection thresholds of three odorants, and general olfactory acuity. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

Heterogeneous Contribution of Microdeletions in the Development of Common Generalized and Focal epilepsies. SUPPLEMENTARY METHODS Epilepsy subtype extended description. Genetic Gereralized Epilepsy (GGE): Features unprovoked tonic and/or clonic seizures, originated inconsistently at some focal point within the brain that rapidly generalizes engaging bilateral distributed spikes and waves discharges on the electroencephalogram. This generalization can include cortical and sub cortical structures but not necessarily the entire cortex[1]. GGE is the most common group of epilepsies accounting for 20% of all cases[2]. It is characterized by an age-related onset and a strong familial aggregation and heritability which allows the assumption of a genetic cause. Although genetic associations have been identified, a broad spectrum of causes is acknowledged and remains largely unsolved [3]. Rolandic Epilepsy (RE): Commonly known also as Benign Epilepsy with Centrotemporal Spikes (BECTS), hallmarks early onset diagnosis (mean onset = 7 years old) with brief, focal hemifacial or oropharyngeal sensorimotor seizures alongside speech arrest and secondarily generalized tonic– clonic seizures, which mainly occur during sleep[4]. Rolandic epilepsy features a broad spectrum of less benign related syndromes called atypical Rolandic epilepsy (ARE), including benign partial epilepsy (ABPE), Landau–Kleffner syndrome(LKS) and epileptic encephalopathy with continuous spike-and-waves during sleep (CSWSS)[5]. Together they are the most common childhood epilepsy with a prevalence of 0.2–0.73/1000 (i.e. _1/2500)[6]. Adult Focal Epilepsy (AFE). Focal epilepsy is characterized by sporadic events of seizures originated within a specific brain region and restricted to one hemisphere. Although they can exhibit more than one network of wave discharges on the electroencephalogram, and different degrees of spreading, they feature a consistent site of origin. -

Inbreeding and Homozygosity in Breast Cancer Survival
www.nature.com/scientificreports OPEN Inbreeding and homozygosity in breast cancer survival Hauke Thomsen1, Miguel Inacio da Silva Filho1, Andrea Woltmann1, Robert Johansson2, Jorunn E. Eyfjörd3, Ute Hamann4, Jonas Manjer5,6, Kerstin Enquist-Olsson7, Received: 15 June 2015 Roger Henriksson2,8, Stefan Herms9,10, Per Hoffmann9,10, Bowang Chen1, Stefanie Huhn1, Accepted: 14 October 2015 Kari Hemminki1,11, Per Lenner2 & Asta Försti1,11 Published: 12 November 2015 Genome-wide association studies (GWASs) help to understand the effects of single nucleotide polymorphisms (SNPs) on breast cancer (BC) progression and survival. We performed multiple analyses on data from a previously conducted GWAS for the influence of individual SNPs, runs of homozygosity (ROHs) and inbreeding on BC survival. (I.) The association of individual SNPs indicated no differences in the proportions of homozygous individuals among short-time survivors (STSs) and long-time survivors (LTSs). (II.) The analysis revealed differences among the populations for the number of ROHs per person and the total and average length of ROHs per person and among LTSs and STSs for the number of ROHs per person. (III.) Common ROHs at particular genomic positions were nominally more frequent among LTSs than in STSs. Common ROHs showed significant evidence for natural selection (iHS, Tajima’s D, Fay-Wu’s H). Most regions could be linked to genes related to BC progression or treatment. (IV.) Results were supported by a higher level of inbreeding among LTSs. Our results showed that an increased level of homozygosity may result in a preference of individuals during BC treatment. Although common ROHs were short, variants within ROHs might favor survival of BC and may function in a recessive manner. -

The Potential Druggability of Chemosensory G Protein-Coupled Receptors
International Journal of Molecular Sciences Review Beyond the Flavour: The Potential Druggability of Chemosensory G Protein-Coupled Receptors Antonella Di Pizio * , Maik Behrens and Dietmar Krautwurst Leibniz-Institute for Food Systems Biology at the Technical University of Munich, Freising, 85354, Germany; [email protected] (M.B.); [email protected] (D.K.) * Correspondence: [email protected]; Tel.: +49-8161-71-2904; Fax: +49-8161-71-2970 Received: 13 February 2019; Accepted: 12 March 2019; Published: 20 March 2019 Abstract: G protein-coupled receptors (GPCRs) belong to the largest class of drug targets. Approximately half of the members of the human GPCR superfamily are chemosensory receptors, including odorant receptors (ORs), trace amine-associated receptors (TAARs), bitter taste receptors (TAS2Rs), sweet and umami taste receptors (TAS1Rs). Interestingly, these chemosensory GPCRs (csGPCRs) are expressed in several tissues of the body where they are supposed to play a role in biological functions other than chemosensation. Despite their abundance and physiological/pathological relevance, the druggability of csGPCRs has been suggested but not fully characterized. Here, we aim to explore the potential of targeting csGPCRs to treat diseases by reviewing the current knowledge of csGPCRs expressed throughout the body and by analysing the chemical space and the drug-likeness of flavour molecules. Keywords: smell; taste; flavour molecules; drugs; chemosensory receptors; ecnomotopic expression 1. Introduction Thirty-five percent of approved drugs act by modulating G protein-coupled receptors (GPCRs) [1,2]. GPCRs, also named 7-transmembrane (7TM) receptors, based on their canonical structure, are the largest family of membrane receptors in the human genome.
