Developmental enhancers initiate transcription and are fundamental to our understanding of developmental networks, evolution and disease. Despite their importance, the properties governing enhancer-promoter interactions and their dynamics during embryogene ...
Proteins are a ubiquitous and indispensable element for every living organism, from simple bacteria to mammals. Already in the simplest organisms, there exist some thousands of different protein species that take up a great variety of structures, and thus ...
Copy number variants (CNVs) influence the expression of genes that map not only within the rearrangement, but also to its flanks. To assess the possible mechanism(s) underlying this "neighboring effect", we compared intrachromosomal interactions and histon ...
Mammalian genes are often transcribed discontinuously as short bursts of RNA synthesis followed by longer silent periods. However, how these "on" and "off" transitions, together with the burst sizes, are modulated in single cells to increase gene expressio ...
Background: CDX2 plays a key part in the differentiation of Caco-2 cells, a colon carcinoma derived cell line that undergoes spontaneous differentiation. The effect of CDX2 expression in Caco-2 cells over time in culture has not been studied yet on a genom ...
How a complex animal can arise from a fertilized egg is one of the oldest and most fascinating questions of biology, the answer to which is encoded in the genome. Body shape and organ development, and their integration into a functional organism all depend ...
Trimethylated histone H3 lysine 4 (H3K4) and H3K27 generally mark transcriptionally active and repressive chromatins, respectively. In most cell types, these two modifications are mutually exclusive and this segregation is crucial for the regulation of gen ...
UCNEbase (http://ccg.vital-it.ch/UCNEbase) is a free, web-accessible information resource on the evolution and genomic organization of ultra-conserved non-coding elements (UCNEs). It currently covers 4351 such elements in 18 different species. The majority ...
Targeted alteration of the genome lies at the heart of the exploitation of S. pombe as a model system. The rate of analysis is often determined by the efficiency with which a target locus can be manipulated. For most loci this is not a problem, however for ...
In mammals, transcription was observed to occur predominantly in bursts, resulting from short and intense periods of gene transcription interspersed by longer silent periods. In order to elucidate the causes and the consequences of discontinuous transcript ...
