Transposable elements (TEs), also called jumping genes, are genetic elements capable of changing their position within the genome of their host. They make up large fractions of genomes, including 45% of human DNA content, according to current estimates.S ...
Horizontal gene transfer (HGT) is widespread in bacteria and archaea and plays a significant role in prokaryotic evolution. One mode of HGT is natural competence for genetic transformation, which allows the organism to take up free DNA from its surrounding ...
Insertional mutagenesis represents a serious adverse effect of gene therapy with integrating vectors. However, although uncontrolled activation of growth-promoting genes in stem cells can predictably lead to oncological processes, this is far less likely i ...
Phenotypically identical mammalian cells often display considerable variability in transcript levels of individual genes. How transcriptional activity propagates in cell lineages, and how this varies across genes is poorly understood. Here we combine live- ...
Background: Superinfection with drug resistant HIV strains could potentially contribute to compromised therapy in patients initially infected with drug-sensitive virus and receiving antiretroviral therapy. To investigate the importance of this potential ro ...
Angiogenesis is the process by which new blood vessels arise from existing ones by the budding out of endothelial cell capillaries from the luminal side of blood vessels. Blood vessel formation is essential for organ development during embryogenesis and is ...
Transcription factor binding site(s) (TFBS) gain and loss (i.e., turnover) is a well-documented feature of cis-regulatory module (CRM) evolution, yet little attention has been paid to the evolutionary force(s) driving this turnover process. The predominant ...
An important aspect of the development of systems biology approaches in metazoans is the characterization of expression patterns of nearly all genes predicted from genome sequences. Such "localizome" maps should provide information on where (in what cells ...
The distribution of 20 variable regions resulting from insertion-deletion events in the genomes of the tubercle bacilli has been evaluated in a total of 100 strains of Mycobacterium tuberculosis, Mycobacterium africanum, Mycobacterium canettii, Mycobacteri ...
Lineage tracing is a basic concept in developmental biology, as well as diseases related to organ development. A reliable method to track cell lineages in human tissues has the potential to greatly contribute to the fields of oncogenesis, tissue renewal, a ...
