Isolation and characterization of anavirulent Candida albicansyeast monomorphic mutant
2003
Mutagenesis of Candida albicans strain ATCC 26555 with N-methyl-nitro-N-nitrosoguanidine followed by plating on solid yeast nitrogen base-N-acetylglucosamine medium at 37 degrees C yielded colony morphology variants that were characterized as forming smooth colonies, in contrast to the rough colonies formed by the parental strain. One yeast monomorphic mutant, CAL4, was studied in detail. Strain CAL4 is defective in filamentous growth, unable to form hyphae or pseudohyphae in vivo and in vitro. These filamentous structures are not elicited by commonly used external stimuli such as serum. The mutant had no obvious alterations in its mannan, glucan or chitin content. The total quantity of non…
Human exome and mouse embryonic expression data implicate ZFHX3, TRPS1, and CHD7 in human esophageal atresia
2020
Introduction Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) occurs approximately 1 in 3.500 live births representing the most common malformation of the upper digestive tract. Only half a century ago, EA/TEF was fatal among affected newborns suggesting that the steady birth prevalence might in parts be due to mutational de novo events in genes involved in foregut development. Methods To identify mutational de novo events in EA/TEF patients, we surveyed the exome of 30 case-parent trios. Identified and confirmed de novo variants were prioritized using in silico prediction tools. To investigate the embryonic role of genes harboring prioritized de novo variants we perfor…
Genome-wide mapping of copy number variations in patients with both anorectal malformations and central nervous system abnormalities
2014
Background: Anorectal malformations (ARM) have a prevalence of around 1 in 2500 live births. In around 50% of patients, the malformation is isolated, while in the remainder it arises within the context of complex genetic abnormalities or a defined genetic syndrome. Recent studies have implicated rare copy number variations (CNVs) in both isolated and nonisolated ARM, and identified plausible candidate genes. Methods: In the present study, array-based molecular karyotyping was performed to identify causative CNVs in 32 sporadic ARM patients with comorbid abnormalities of the central nervous system (CNS). This phenotype was selected to enrich for rare CNVs, since previous research has implica…
Value of genetic and epigenetic testing as biomarkers of response to antidepressant treatment
2013
Major depressive disorder (MDD) is one of the most prevalent and disabling psychiatric disorders worldwide and therefore an important public health priority. The selection process of antidepressant treatment is primarily guided by trial and error, and the outcomes with current antidepressant strategies are disappointing. The biological background of the disease is heterogeneous with presumably multiple biological systems involved. With the aim to individualize antidepressant treatment, multiple candidate gene and a few genome-wide association studies have been performed, but so far with very limited success. To address the dynamic changes of depressive symptoms and their response to treatme…

Debating Europe: Effects of the “Eurovision Debate” on EU Attitudes of Young German Voters and the Moderating Role Played by Political Involvement
2016
In the run-up to the elections to the European Parliament in 2014, EU citizens had the unprecedented opportunity to watch televised debates between the candidates running for president of the European Commission. The most important debate was the so-called "Eurovision debate", which was broadcasted in almost all EU member states. In this study we explore the responses of a sample of 110 young German voters, who watched this debate, to the candidates' messages and whether exposure to the debate caused a shift in the respondents' attitudes towards the EU. Combining data from a quasi-experiment, real-time response data, and data from a content analysis of the debate, we find that respondents' …
Exome sequencing of three cases of familial exceptional longevity
2014
Exceptional longevity (EL) is a rare phenotype that can cluster in families, and co-segregation of genetic variation in these families may point to candidate genes that could contribute to extended lifespan. In this study, for the first time, we have sequenced a total of seven exomes from exceptionally long-lived siblings (probands ≥ 103 years and at least one sibling ≥ 97 years) that come from three separate families. We have focused on rare functional variants (RFVs) which have ≤ 1% minor allele frequency according to databases and that are likely to alter gene product function. Based on this, we have identified one candidate longevity gene carrying RFVs in all three families, APOB. Inter…
Cloning and characterization of a cDNA coding forCandida albicanspolyubiquitin
1996
Immunoscreening of a Candida albicans cDNA library in the expression vector lambda gt11 with rabbit polyclonal antibodies against the 37 kDa cell surface laminin receptor of C albicans resulted in the isolation of a cDNA clone of 0.9 kb. Sequencing of this clone demonstrated a full length open reading frame encoding the polyubiquitin, which contains three tandem copies, head-to-tail spacerless repeats, of the 228 nucleotides coding for the 76 amino acids of the ubiquitin protein, which is identical to that of Saccharomyces cerevisiae. The third copy possesses an extra C-terminal amino acid which is distinct to that found in S. cerevisiae. Northern blot analysis revealed a single mRNA popula…
Interactions between dietary n-3 fatty acids and genetic variants and risk of disease
2012
Nutritional genomics has undergone rapid development and the concept is now very popular with the general public. Therefore, there is increasing demand for knowledge on adapting dietary composition to the genome. Our aim has been to undertake a systematic review so as to find out the level of evidence existing on whether the effects of n-3 fatty acids on health can be modulated by genetic variation. A systematic literature search was conducted on studies that jointly analyse the effect of one or more genetic variants in candidate genes and n-3 fatty acids. Both observational and experimental studies were included. Results are classified in accordance with whether the study was undertaken on…
