Mapping and structure of DMXL1, a human homologue of the DmX gene from Drosophila melanogaster coding for a WD repeat protein.

2000

The DmX gene was recently isolated from the X chromosome of Drosophila melanogaster. TBLASTN searches of the dbEST databases revealed sequences with a high level of similarity to DmX in a variety of different species, including insects, nematodes, and mammals showing that DmX is an evolutionarily highly conserved gene. Here we describe the cloning of the cDNA and the chromosomal localization of one of the human homologues of DmX, Dmx-like 1 (DMXL1). The human DMXL1 gene codes for a large mRNA of 11 kb with an open reading frame of 3027 amino acids. The putative protein belongs to the superfamily of WD repeat proteins, which have mostly regulatory functions. The DMXL1 protein contains an exc…

ZFWD: a novel subfamily of plant proteins containing a C3H zinc finger and seven WD40 repeats

2000

We describe a new subfamily of WD repeat proteins characterised by the presence of a C3H zinc finger at the N-terminal part of the protein associated with seven WD40 repeats. We have identified four members of this subfamily in Arabidopsis thaliana, one of them with associated expressed sequence tags (ESTs). We have also identified homologous ESTs in rice, cotton, maize, poplar, pine tree and the ice plant. We do not observe animal homologues, suggesting that this subfamily could be specific for plants. Our data suggest an important role for these proteins. Based on the high sequence conservation within the conserved domains, we suggest that these proteins could have a regulatory function.

Immunological and pathological status of gilthead sea bream (Sparus aurata L.) under different long-term feeding regimes

2003

The possible influence of the feeding regime (FR) on the immune system and pathological status of gilthead sea bream was studied. Two growth trials were performed starting at different seasons (trial 1 = March; trial 2 = June) under controlled experimental conditions. In both trials, FR-1 groups received a restricted amount of food, whereas FR-2 groups were fed to visual satiety. The pathology study included parasitological and bacteriological examination, and the immunological traits analysed were respiratory burst activity of head kidney leucocytes, serum lysozyme and alternative pathway complement activity (ACH50). The immunological status of gilthead sea bream not only was not impaired …

Molecular cloning of the RPS0 gene from Candida tropicalis.

2001

The Saccharomyces cerevisiae RPS0 A and B genes encode proteins essential for maturation of the 40S ribosomal subunit precursors. We have isolated a homologue of the RPS0 gene from Candida tropicalis, which we named CtRPS0. The C. tropicalisRPS0 encodes a protein of 261 amino acid residues with a predicted molecular weight of 28.65 kDa and an isoelectric point of 4.79. CtRps0p displays significant amino acid sequence homology with Rps0p from C. albicans, S. cerevisiae, Neurospora crassa, Schizosaccharomyces pombe, Pneumocystis carinii and higher organisms, such as human, mouse and rat. CtRPS0 on a high copy number vector can complement the lethal phenotype linked to the disruption of both R…

Assignment of the group A rotavirus NSP4 gene into genotypes using a hemi-nested multiplex PCR assay: a rapid and reproducible assay for strain surve…

2009

The rotavirus non-structural protein NSP4 has been implicated in a number of biological functions during the rotavirus cellular cycle and pathogenesis, and has been addressed as a target for vaccine development. The NSP4 gene has been classified into six genotypes (A–F). A semi-nested triplex PCR was developed for genotyping the major human NSP4 genotypes (A–C), which are common in human rotavirus strains but are also shared among most mammalian rotavirus strains. A total of 192 previously characterized human strains representing numerous G and P type specificities (such as G1P[8], G1P[4], G2P[4], G3P[3], G3P[8], G3P[9], G4P[6], G4P[8], G6P[4], G6P[9], G6P[14], G8P[10], G8P[14], G9P[8], G9P…

Increased serum miR-193a-5p during non-alcoholic fatty liver disease progression: Diagnostic and mechanistic relevance

2022

Background & Aims Serum microRNA (miRNA) levels are known to change in non-alcoholic fatty liver disease (NAFLD) and may serve as useful biomarkers. This study aimed to profile miRNAs comprehensively at all NAFLD stages. Methods We profiled 2,083 serum miRNAs in a discovery cohort (183 cases with NAFLD representing the complete NAFLD spectrum and 10 population controls). miRNA libraries generated by HTG EdgeSeq were sequenced by Illumina NextSeq. Selected serum miRNAs were profiled in 372 additional cases with NAFLD and 15 population controls by quantitative reverse transcriptase PCR. Results Levels of 275 miRNAs differed between cases and population controls. Fewer differences were seen wi…

The role of the silicatein-alpha interactor silintaphin-1 in biomimetic biomineralization.

2008

Biosilicification in sponges is initiated by formation of proteinaceous filaments, predominantly consisting of silicateins. Silicateins enzymatically catalyze condensation of silica nanospheres, resulting in symmetric skeletal elements (spicules). In order to create tailored biosilica structures in biomimetic approaches it is mandatory to elucidate proteins that are fundamental for the assembly of filaments. Silintaphin-1 is a core component of modularized filaments and also part of a spicule-enfolding layer. It bears no resemblance to other proteins, except for the presence of an interaction domain that is fundamental for its function as scaffold/template. In the presence of silicatein sil…

MaT²SMC: materials for teaching together: science andmMathematics teachers collaborating for better results

2016

Let us start with an important statement: Mathematics and Science teachers do a good, and often an outstanding, job in teaching young people the basic knowledge of their respective fields! It is not the intent of this book to criticize what they do or how they do it. Keeping that in mind, and noting the fact that the teaching content of these fields intersects and overlaps, we observed – and this took us by surprise – that there is hardly any collaboration or consultancy between mathematics and science teachers (or textbook authors). Mathematics teachers often use science contexts in tasks, and science teachers often use mathematics, however they are usually working independently. Science c…
