The heritable component of panic disorder is estimated at 48\%. Glutamic acid dehydrogenase GAD1, the key enzyme for the synthesis of the inhibitory and anxiolytic neurotransmitter GABA, is supposed to influence various mental disorders, including mood and anxiety disorders. In a recent association study in depression, which is highly comorbid with panic disorder, GAD1 risk allele associations were restricted to females. Methodology/Principal Findings: Nineteen single nucleotide polymorphisms (SNPs) tagging the common variation in GAD1 were genotyped in two independent gender and age matched case-control samples (discovery sample n = 478; replication sample n = 584). Thirteen SNPs passed quality control and were examined for gender-specific enrichment of risk alleles associated with panic disorder by using logistic regression including a genotype6gender interaction term. The latter was found to be nominally significant for four SNPs (rs1978340, rs3762555, rs3749034, rs2241165) in the discovery sample; of note, the respective minor/risk alleles were associated with panic disorder only in females. These findings were not confirmed in the replication sample; however, the genotype6gender interaction of rs3749034 remained significant in the combined sample. Furthermore, this polymorphism showed a nominally significant association with the Agoraphobic Cognitions Questionnaire sum score. Conclusions/Significance: The present study represents the first systematic evaluation of gender-specific enrichment of risk alleles of the common SNP variation in the panic disorder candidate gene GAD1. Our tentative results provide a possible explanation for the higher susceptibility of females to panic disorder.}, subject = {Medizin}, language = {en} } @article{SchuemannGrossBaueretal.2021, author = {Sch{\"u}mann, Franziska Lea and Groß, Elisabeth and Bauer, Marcus and Rohde, Christian and Sandmann, Sarah and Terziev, Denis and M{\"u}ller, Lutz P. and Posern, Guido and Wienke, Andreas and Fend, Falko and Hansmann, Martin-Leo and Klapper, Wolfram and Rosenwald, Andreas and Stein, Harald and Dugas, Martin and M{\"u}ller-Tidow, Carsten and Wickenhauser, Claudia and Binder, Mascha and Weber, Thomas}, title = {Divergent effects of EZH1 and EZH2 protein expression on the prognosis of patients with T-cell lymphomas}, series = {Biomedicines}, volume = {9}, journal = {Biomedicines}, number = {12}, issn = {2227-9059}, doi = {10.3390/biomedicines9121842}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-252155}, year = {2021}, abstract = {T-cell lymphomas are highly heterogeneous and their prognosis is poor under the currently available therapies. Enhancers of zeste homologue 1 and 2 (EZH1/2) are histone H3 lysine-27 trimethyltransferases (H3K27me3). Despite the rapid development of new drugs inhibiting EZH2 and/or EZH1, the molecular interplay of these proteins and the impact on disease progression and prognosis of patients with T-cell lymphomas remains insufficiently understood. In this study, EZH1/2 mutation status was evaluated in 33 monomorphic epitheliotropic intestinal T-cell lymphomas by next generation sequencing and EZH1/2 and H3K27me3 protein expression levels were detected by immunohistochemistry in 46 T-cell lymphomas. Correlations with clinicopathologic features were analyzed and survival curves generated. No EZH1 mutations and one (3\%) EZH2 missense mutation were identified. In univariable analysis, high EZH1 expression was associated with an improved overall survival (OS) and progression-free survival (PFS) whereas high EZH2 and H3K27me3 expression were associated with poorer OS and PFS. Multivariable analysis revealed EZH1 (hazard ratio (HR) = 0.183; 95\% confidence interval (CI): 0.044-0.767; p = 0.020;) and EZH2 (HR = 8.245; 95\% CI: 1.898-35.826; p = 0.005) to be independent, divergent prognostic markers for OS. In conclusion, EZH1/2 protein expression had opposing effects on the prognosis of T-cell lymphoma patients.}, language = {en} } @article{BemmBeckerLarischetal.2016, author = {Bemm, Felix and Becker, Dirk and Larisch, Christina and Kreuzer, Ines and Escalante-Perez, Maria and Schulze, Waltraud X. and Ankenbrand, Markus and Van de Weyer, Anna-Lena and Krol, Elzbieta and Al-Rasheid, Khaled A. and Mith{\"o}fer, Axel and Weber, Andreas P. and Schultz, J{\"o}rg and Hedrich, Rainer}, title = {Venus flytrap carnivorous lifestyle builds on herbivore defense strategies}, series = {Genome Research}, volume = {26}, journal = {Genome Research}, number = {6}, doi = {10.1101/gr.202200.115}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-188799}, pages = {812-825}, year = {2016}, abstract = {Although the concept of botanical carnivory has been known since Darwin's time, the molecular mechanisms that allow animal feeding remain unknown, primarily due to a complete lack of genomic information.

At the same time, a massive induction of general defense responses is accompanied by the repression of cell death-related genes/processes. We hypothesize that the carnivory syndrome of Dionaea evolved by exaptation of ancient defense pathways, replacing cell death with nutrient acquisition.}, language = {en} } @article{GrimmWeberKittelSchneideretal.2020, author = {Grimm, Oliver and Weber, Heike and Kittel-Schneider, Sarah and Kranz, Thorsten M. and Jacob, Christian P. and Lesch, Klaus-Peter and Reif, Andreas}, title = {Impulsivity and Venturesomeness in an Adult ADHD Sample: Relation to Personality, Comorbidity, and Polygenic Risk}, series = {Frontiers in Psychiatry}, volume = {11}, journal = {Frontiers in Psychiatry}, issn = {1664-0640}, doi = {10.3389/fpsyt.2020.557160}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-219751}, year = {2020}, abstract = {While impulsivity is a basic feature of attention-deficit/hyperactivity disorder (ADHD), no study explored the effect of different components of the Impulsiveness (Imp) and Venturesomeness (Vent) scale (IV7) on psychiatric comorbidities and an ADHD polygenic risk score (PRS). We used the IV7 self-report scale in an adult ADHD sample of 903 patients, 70\% suffering from additional comorbid disorders, and in a subsample of 435 genotyped patients. Venturesomeness, unlike immediate Impulsivity, is not specific to ADHD. We consequently analyzed the influence of Imp and Vent also in the context of a PRS on psychiatric comorbidities of ADHD. Vent shows a distinctly different distribution of comorbidities, e.g., less anxiety and depression. PRS showed no effect on different ADHD comorbidities, but correlated with childhood hyperactivity. In a complementary analysis using principal component analysis with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition ADHD criteria, revised NEO Personality Inventory, Imp, Vent, and PRS, we identified three ADHD subtypes. These are an impulsive-neurotic type, an adventurous-hyperactive type with a stronger genetic component, and an anxious-inattentive type. Our study thus suggests the importance of adventurousness and the differential consideration of impulsivity in ADHD. The genetic risk is distributed differently between these subtypes, which underlines the importance of clinically motivated subtyping. Impulsivity subtyping might give insights into the organization of comorbid disorders in ADHD and different genetic background.}, language = {en} } @article{GroebnerWorstWeischenfeldtetal.2018, author = {Gr{\"o}bner, Susanne N. and Worst, Barbara C. and Weischenfeldt, Joachim and Buchhalter, Ivo and Kleinheinz, Kortine and Rudneva, Vasilisa A. and Johann, Pascal D. and Balasubramanian, Gnana Prakash and Segura-Wang, Maia and Brabetz, Sebastian and Bender, Sebastian and Hutter, Barbara and Sturm, Dominik and Pfaff, Elke and H{\"u}bschmann, Daniel and Zipprich, Gideon and Heinold, Michael and Eils, J{\"u}rgen and Lawerenz, Christian and Erkek, Serap and Lambo, Sander and Waszak, Sebastian and Blattmann, Claudia and Borkhardt, Arndt and Kuhlen, Michaela and Eggert, Angelika and Fulda, Simone and Gessler, Manfred and Wegert, Jenny and Kappler, Roland and Baumhoer, Daniel and Stefan, Burdach and Kirschner-Schwabe, Renate and Kontny, Udo and Kulozik, Andreas E. and Lohmann, Dietmar and Hettmer, Simone and Eckert, Cornelia and Bielack, Stefan and Nathrath, Michaela and Niemeyer, Charlotte and Richter, G{\"u}nther H. and Schulte, Johannes and Siebert, Reiner and Westermann, Frank and Molenaar, Jan J. and Vassal, Gilles and Witt, Hendrik and Burkhardt, Birgit and Kratz, Christian P. and Witt, Olaf and van Tilburg, Cornelis M. and Kramm, Christof M. and Fleischhack, Gudrun and Dirksen, Uta and Rutkowski, Stefan and Fr{\"u}hwald, Michael and Hoff, Katja von and Wolf, Stephan and Klingebeil, Thomas and Koscielniak, Ewa and Landgraf, Pablo and Koster, Jan and Resnick, Adam C. and Zhang, Jinghui and Liu, Yanling and Zhou, Xin and Waanders, Angela J. and Zwijnenburg, Danny A. and Raman, Pichai and Brors, Benedikt and Weber, Ursula D. and Northcott, Paul A. and Pajtler, Kristian W. and Kool, Marcel and Piro, Rosario M. and Korbel, Jan O. and Schlesner, Matthias and Eils, Roland and Jones, David T.

Here we present a comprehensive analysis of genetic alterations in a pan-cancer cohort including 961 tumours from children, adolescents, and young adults, comprising 24 distinct molecular types of cancer. Using a standardized workflow, we identified marked differences in terms of mutation frequency and significantly mutated genes in comparison to previously analysed adult cancers. Genetic alterations in 149 putative cancer driver genes separate the tumours into two classes: small mutation and structural/copy-number variant (correlating with germline variants). Structural variants, hyperdiploidy, and chromothripsis are linked to TP53 mutation status and mutational signatures. Our data suggest that 7-8\% of the children in this cohort carry an unambiguous predisposing germline variant and that nearly 50\% of paediatric neoplasms harbour a potentially druggable event, which is highly relevant for the design of future clinical trials.}, language = {en} }
