Every organism—from a seedling to a president—must protect its DNA at all costs, but precisely how a cell distinguishes between damage to its own DNA and the foreign DNA of an invading virus has remained a mystery. Now, scientists at the Salk Institute have discovered critical details of how a cell’s response system tells the difference between these two perpetual threats. The discovery…
Researchers at the Virginia Bioinformatics Institute at Virginia Tech have uncovered key cellular functions that help regulate inflammation -- a discovery that could have important implications for the treatment of allergies, heart disease, and certain forms of cancer.
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.
For patients with an often-deadly form of leukemia, new research suggests that lingering cancer-related mutations – detected after initial treatment with chemotherapy – are associated with an increased risk of relapse and poor survival.
Innovative presentations, ground-breaking science and inspirational lectures underlined the diversity of sessions at the British Cardiovascular Society 2015 conference held in Manchester this June.
As new cardiac genetic testing panels become available, cardiologists have been warned not to lose sight of the importance of comprehensive clinical evaluation. While genetic testing is helping to identify more people at risk of inherited conditions, experts stress they are only part of the diagnostic toolkit.
A ground-breaking genetic testing programme for an inherited and potentially-deadly high cholesterol condition has been extended to more United Kingdom health trusts.
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.

For over one hundred years, scientists have debated the question of the origins of the lymphatic system – a parallel system to the blood vessels that serves as a conduit for everything from immune cells to fat molecules to cancer cells. This issue has now been resolved by Dr. Karina Yaniv of Weizmann Institute’s Biological Regulation Department. In a study reported in Nature, she and her team…
American Society of Human Genetics issues recommendations on age-appropriate genetic testing in children and adolescents.
Tumor suppressor genes protect against cancer. Until now, scientists have had to perform complex experiments to detect whether or not a mutation or loss of this gene type does, in fact, cause cancer. Scientists from the German Cancer Research Center (DKFZ) have now used a new gene technology method called CRISPR/Cas9 technology for this detection.
Weizmann Institute scientists identify a potential drug molecule that stops cancer cells, but not healthy ones, from getting their “mail”.
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…
This article discusses examples of applications of genetic analyses in coagulation disorders and haematological and oncological diseases. Professor Christine Mannhalter highlights the impact changes have on the occurrence and severity of diseases and their influence on therapy response. Report: Christine Mannhalter
Researchers in Canada and the U.K. have for the first time sequenced and assembled de novo the full genome of a living organism, the bacteria Escherichia Coli, using Oxford Nanopore's MinIONTM device, a genome sequencer that can fit in the palm of your hand.
“I am very concerned about the impact that Angelina Jolie has on the media,” Walter Rocca, professor of epidemiology and neurology at the Mayo Clinic in Rochester, Minnesota, stated. He wasn’t hinting to Jolie’s acting choices or waifish silhouette, but to the confusion surrounding her decision to remove her ovaries to prevent ovarian cancer. By Mélisande Rouger
Mutations in ARID1a, which are common in many cancer types, disrupt DNA damage repair in cancer cells, allowing the cancer to progress. This gene may also be an Achilles' heel when treating certain tumors, according to a team of researchers at The University of Texas MD Anderson Cancer Center.
The EU-funded MycoSynVac project combines gene engineering and biotechnology to design a novel veterinary vaccine chassis based on the bacterium Mycoplasma pneumoniae.
Knee injuries are the bane of athletes everywhere, from professionals and college stars to weekend warriors. Current surgical options for repairing damaged cartilage caused by knee injuries are costly, can have complications, and often are not very effective in the long run. Even after surgery, cartilage degeneration can progress leading to painful arthritis. But a University of Iowa orthopedics…
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.
The UK pathology sector faces numerous challenges as it strives to create a future medical laboratory workforce. As in many divisions of the National Health Service (NHS), this area has an ageing population yet must evolve against a backdrop of fast-developing technologies, emerging science, financial constraints and the challenge of working in tandem with the private sector. Report: Mark…
The proposed EU draft IVD regulation looks set to have major implications for IVD manufacturers and laboratory-developed tests (LDTs). Replacing a current system that is inflexible, unresponsive and does not effectively protect patients, the new regulation will apply directly to all 28 EU countries and govern the manufacture and marketing of in vitro diagnostic devices (IVDs).
