When our cells copy their DNA to grow and replicate, it’s vital the process runs smoothly. To get this right, cells use a complex “machine”, made from many hundreds of components. This machine is built afresh, moment by moment as it’s needed during the copying process. This assembly–de-assembly is vital to accurate and efficient copying.
A new study at the University of Haifa has used “big data” analytical methods to reveal the “social character” of genes – a phenomenon in certain diseases whereby genes operate jointly rather than independently. “The problem is that the possible number of combinations of different genes is enormous, and it is almost impossible to examine them all effectively and reliably,” the…
An LMU team has uncovered a new role for the protein Atrx, which is involved in various aspects of gene expression. The new work shows that the protein is also involved in silencing endogenous retroviral genomes integrated in cellular DNA.
A new technology that will dramatically enhance investigations of epigenomes, the machinery that turns on and off genes and a very prominent field of study in diseases such as stem cell differentiation, inflammation and cancer, is reported in the research journal Nature Methods.
Chemists at Caltech have developed a new sensitive technique capable of detecting colorectal cancer in tissue samples—a method that could one day be used in clinical settings for the early diagnosis of colorectal cancer.
American Society of Human Genetics issues recommendations on age-appropriate genetic testing in children and adolescents.
A group of researchers, lead by Vasily M. Studitsky, professor at the Lomonosov Moscow State University, discovered a new mechanism of DNA repair, which opens up new perspectives for the treatment and prevention of neurodegenerative diseases. The article describing their discovery is published in AAAS' first open access online-only journal Science Advances.
It may come as a bit of a surprise to learn that bacteria have an immune system – in their case to fight off invasive viruses called phages. And like any immune system – from single-celled to human – the first challenge of the bacterial immune system is to detect the difference between “foreign” and “self.” This is far from simple, as viruses, bacteria and all other living things…
In collaboration with colleagues from California and New York, researchers of the Paul-Ehrlich-Institut have identified a cytosolic receptor which enables cells of the immune system to recognize HIV and to trigger an immune response. The findings of the researchers may be a useful tool for creating an effective endogenous immune response against HIV and helpful to boost vaccine responses.
LMU researchers demonstrate for the first time that bacteriophages (bacterial viruses) carry genetic instructions for proteins that mediate the transport of their DNA to specialized replication sites in the host cell.
Scientists from the Hubrecht Institute and the University Medical Center Utrecht (UMC Utrecht) have developed a cell culture model of human colon cancer progression. This model mimics the situation in patients more closely than any other colon cancer model so far. It enables researchers to study processes involved in colon cancer development and find new cancer drugs.
Researchers from the Universitat Autònoma de Barcelona (UAB) and the UAB Institute of Biotechnology and Biomedicine discovered that the signalling route triggered by the ATM protein regulates DNA repair during the production of spermatocytes by meiosis, the cell division process which yields spermatozoa.
Johns Hopkins scientists have discovered that neurons are risk takers: They use minor ‘DNA surgeries’ to toggle their activity levels all day, every day. Since these activity levels are important in learning, memory and brain disorders, the researchers think their finding will shed light on a range of important questions.
Researchers discovered that NSF unravels a single SNARE complex using one round ATP turnover by tearing the complex with a single burst, contradicting a previous theory that it unwinds in a processive manner.
USA - Oocyte modification to eliminate inherited mitochondrial defects in a human embryo was the subject of a globally scrutinised Food and Drug Administration (FDA) hearing held in February.
Future of DNA sequencing will shift from a laboratory-based setup to point of care testing in the next 5 years
