Analysis of a RECQL splicing mutation, c.1667_1667+3delAGTA, in breast cancer patients and controls from Central Europe.

RECQL is a DNA helicase required for genomic stability. Two studies have recently identified RECQL as a novel breast cancer susceptibility gene. The most common RECQL mutation, the 4 bp-deletion c.

Prevalence of Nutrition and Health-Related Claims on Pre-Packaged Foods: A Five-Country Study in Europe.

This study is part of the research undertaken in the EU funded project CLYMBOL ("Role of health-related CLaims and sYMBOLs in consumer behaviour"). The first phase of this project consisted of mapping the prevalence of symbolic and non-symbolic nutrition and health-related claims (NHC) on foods and non-alcoholic beverages in five European countries. Pre-packaged foods and drinks were sampled based on a standardized sampling protocol, using store lists or a store floor plan.

Dually inducible TetON systems for tissue-specific conditional gene expression in zebrafish.

Systems for spatial and temporal control of gene expression are essential for developmental studies and are of particular importance for research in adult model organisms. We present two modified dually inducible TetON systems for tissue-specific conditional control of gene expression in zebrafish based on (i) a tetracycline inducible transcriptional activator (TetActivator) fused to the ligand binding domain of a mutated glucocorticoid receptor (TetA-GBD) and (ii) a TetActivator fused with a domain of the Ecdysone receptor (TetA-EcR). Both systems showed strong induction of tetracycline-responsive promoters upon administration of the appropriate ligands (doxycycline and dexamethasone for TetA-GBD, and doxycycline and tebufenozide for TetA-EcR), and undetectable leakiness when compared with classical TetActivators.
