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).
The genes BRCA1 and BRCA2 play a significant role in hereditary breast and ovarian cancers. Recent media attention has focused on American actress Angelina Jolie's decision to have her ovaries and fallopian tubes surgically removed after genetic testing for such cancers.
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.
Australian researchers have found that so-called 'triple-negative breast cancers' are two distinct diseases that likely originate from different cell types. This helps explain why survival prospects for women with the diagnosis tend to be either very good or very bad.
Cells have two different programs to safeguard them from getting out of control and developing cancer. One of them is senescence (biological aging). It puts cancer cells into a permanent sleep so they no longer divide and grow in an uncontrolled way. Now the research group led by Professor Walter Birchmeier (Max Delbrück Center for Molecular Medicine, MDC, Berlin-Buch) has discovered that an…
The ‘MRI of the Adnexa, Essentials and Beyond’ session from at the MR 2015 symposium held in Garmisch, Austria, presented tips and tricks in clinical routine before moving to research that combines imaging and genomic data to better evaluate ovarian cancer. Report: John Brosky
Molecular profiling is transforming brain cancer management and radiologists must get to grips with the upcoming paradigm that will affect the way they report findings. Renowned neuroradiologist Professor Anne G. Osborn from the University of Utah, School of Medicine, Salt Lake City, unveiled the latest advances in brain pathology during the Nikola Tesla Honorary Lecture last week at ECR…
The mechanical basis of mitosis has only been understood in fragments so far. Scientists at Technische Universität Dresden have now been able to add another piece to the puzzle of cell biological mechanisms, as they report in the latest issue of the renowned scientific journal “Cell” .
A magnetic resonance spectroscopy (MRS) technique that monitors biochemical changes in tissue could improve the management of women at risk of breast cancer.
Women with metastatic breast cancer know they have a slim chance of long-term survival. The question is whether personalised therapy could extend their lives. Report: Cynthia E Keen
The term ‘cancer’ describes more than 200 different diseases and every single one needs to be clearly understood and requires, ideally, individual treatment. To do this we need to deepen our understanding the cancer genome. Report: Anja Behringer
In studies on prostate cancer, scientists from the German Cancer Research Center (DKFZ) simultaneously investigated the genetic and epigenetic development of the tumors.
Johns Hopkins researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that, if confirmed in larger studies, could give doctors a simple blood test to reliably predict a person’s risk of attempting suicide.
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.
