Cancer-linked mutation accelerates growth of abnormal stroke-causing brain blood vessels

Researchers have discovered an explanation for why cerebral cavernous malformations (CCMs)—clusters of dilated blood vessels in the brain—can suddenly grow to cause seizures or stroke. Specifically, they found that a specific, acquired mutation in a cancer-causing gene (PIK3CA) could exacerbate existing CCMs in the brain. Furthermore, repurposing an already existing […]

Scientists develop new class of cancer drug with potential to treat leukaemia

Scientists have made a promising step towards developing a new drug for treating acute myeloid leukaemia, a rare blood disorder. In a study published today in Nature, Cambridge researchers report a new approach to cancer treatment that targets enzymes which play a key role in translating DNA into proteins and which […]

New cancer algorithm flags genetic weaknesses in tumours

A new way to identify tumours that could be sensitive to particular immunotherapies has been developed using data from thousands of NHS cancer patient samples sequenced through the 100,000 Genomes Project. The MMRDetect clinical algorithm makes it possible to identify tumours that have ‘mismatch repair deficiencies’ and then improve the personalisation of cancer therapies to exploit […]

New technology could allow more cancer patients to benefit from immunotherapy

Professor Naoto Hirano of the Temerty Faculty of Medicine and collaborators have developed a new technology that rigorously and robustly identifies the immune cells that are capable of recognizing and eliminating cancer cells. The findings, published in Nature Biotechnology, pave the way for novel immunotherapies to help more patients, regardless of their genetic ancestry, […]

Epilepsy discovery reveals why some seizures prove deadly

New research from the University of Virginia School of Medicine has shed light on the No. 1 cause of epilepsy deaths, suggesting a long-sought answer for why some patients die unexpectedly following an epileptic seizure. The researchers found that a certain type of seizure is associated with sudden death in a […]

New method preserves viable fruit fly embryos in liquid nitrogen

Cryopreservation, or the long-term storage of biomaterials at ultralow temperatures, has been used across cell types and species. However, until now, the practical cryopreservation of the fruit fly (Drosophila melanogaster) — which is crucial to genetics research and critical to scientific breakthroughs benefiting human health — has not been available. […]

DNA replication: A game of precision

Stretching out the DNA in all 46 chromosomes packed into one human cell would make a string of DNA two meters long. Accurately replicating all that DNA is vital to survival; cells must control this process with tremendous precision in time and space. Origin recognition complexes (ORCs) initiate the task […]

Understanding how DNA repairs itself may lead to better cancer treatments

From cancer treatment to sunlight, radiation and toxins can severely damage DNA in both harmful and healthy cells. While the body has evolved to efficiently treat and restore damaged cells, the mechanisms that allow this natural repair remain misunderstood. In a new study, Northwestern University researchers have used cryogenic electron […]

Genetic Changes in Head and Neck Cancer, Immunotherapy Resistance Identified

A multi-institutional team of researchers has identified both the genetic abnormalities that drive pre-cancer cells into becoming an invasive type of head and neck cancer and patients who are least likely to respond to immunotherapy. “Through a series of surprises, we followed clues that focused more and more tightly on […]

Early MR scans found more people with broken-heart syndrome

In almost ten per cent of myocardial infarctions, no obvious cause in the coronary artery can be found. Some of the patients are diagnosed with the broken-heart syndrome, while others are left without a diagnosis. A new study from Karolinska Institutet in Sweden suggests that early magnetic resonance (MR) imaging […]

Overweight or obese COVID-19 patients at risk of more severe disease

COVID-19 patients who are overweight or obese have more severe symptoms and are highly likely to require invasive respiratory support, according to a new international study. The research, led by The University of Queensland and the Murdoch Children’s Research Institute (MCRI), found obese patients had a 73 per cent greater chance of […]
