It is the Methusalem among fishkind: The colorful Clownfish lives longer than 20 years in the Aquarium. Researchers of the Scuola Normale Superiore in Pisa, Italy, in collaboration with the Leibniz Institute on Aging (FLI) in Jena, Germany, have investigated the genetics behind the longevity of Clownfish. By sequencing the genome and comparing the sequences with other species, they were able to…
New findings about a fatal form of blood cancer could aid the development of new drugs with significantly less harmful side effects than existing chemotherapy. The discovery could lead to novel treatments that efficiently eliminate blood cancer cells in acute myeloid leukaemia (AML), without harming healthy blood cells. Researchers have discovered how a protein in the body plays a key role in AML…
Women with early, low risk, hormone-driven breast cancer are less likely to have a recurrence of their disease if they have radiotherapy after surgery, as well as anti-hormone treatment, according to results from a trial that has followed 869 women for ten years. New findings from the 8 A trial of the Austrian Breast and Colorectal Cancer Study Group (ABCSG), presented at the ESTRO 38 conference,…
Scientists could help match cancer patients with no other treatment options to clinical trials with experimental medicines, by analysing the genetic faults in a sample of their blood. The researchers, funded by Cancer Research UK, The Christie Charity, AstraZeneca and the NIHR Manchester Biomedical Research Centre (BRC), demonstrated in their feasibility study that a blood test can be carried out…
When the first antibiotics were discovered in the early 20th century, the rate of death from infectious diseases fell dramatically. But the emergence of multidrug-resistant bacteria as a result of antibiotic misuse is raising fears that by 2050, these same diseases will once again become the leading cause of death worldwide. In a bid to boost the arsenal available to tackle this threat,…
Half of patients prescribed statins in primary care fail to reach ‘healthy’ cholesterol levels after two years of treatment with these drugs, reveals research published online in the journal Heart. The findings back up those of previous studies, and highlight the need for personalised medicine to tackle high cholesterol and lower the significantly increased risks of future heart disease and…
BioMérieux and the Laboratory of Medical Microbiology at the University of Antwerp announced at ECCMID (European Congress of Clinical Microbiology & Infectious Diseases) the 2018 results of the Global Point Prevalence Survey (GLOBAL-PPS), a study of antibiotic use and antimicrobial resistance (AMR) in hospitals around the world. Since its launch in 2015, this survey has been conducted in…
Non-alcoholic fatty liver disease (NAFLD) is a condition where fat accumulates in the liver and has become the most common liver disease worldwide. While NAFLD shows few or no symptoms at initial stages, it is a potentially serious disease which can progress to an inflammatory state called steatohepatitis (NASH), which can lead to liver cirrhosis and cancer. Fatty liver disease can be managed by…
A new study provides critical insight into a little-known, yet relatively common, inherited neurological condition called Charcot-Marie-Tooth disease (CMT). The findings point to a pathway to possible treatments for this disease and better understanding of other neurodegenerative disorders, including Alzheimer's disease, that affect millions. The study focused on two related proteins, MFN2 and…
Researchers at Mount Sinai have developed a novel approach to cancer immunotherapy, injecting immune stimulants directly into a tumor to teach the immune system to destroy it and other tumor cells throughout the body. The “in situ vaccination” worked so well in patients with advanced-stage lymphoma that it is also undergoing trials in breast and head and neck cancer patients, according to a…
Scientists have identified key changes in immune cells within cancerous tumours that could help improve the development of treatments. The study, which has been published in the journal Cancer Cell, also found a set of genes that are expressed at high levels in breast cancer tumours and linked to more aggressive cancer types. Researchers say the discoveries offer clues to diagnosis and predicting…
Viruses are often used as vehicles for delivery in gene therapy because they’re engineered not to damage the cell once they get there, but neglecting to consider how the virus will exit the cell could have consequences. Some viruses use a molecule called heparan sulfate to help them attach to cells. The molecule, found in many different kinds of cells (including those from animal tissue), could…
Research from King’s College London provides the first evidence of an association between air pollution and psychotic experiences in adolescence. The study, published in JAMA Psychiatry, provides a potential explanation for why growing up in cities is a risk factor for psychosis. This is the first time researchers have linked detailed geographical air pollution data with a representative sample…
Inside the body, disease and injury can leave behind quite the mess — a scattering of cellular debris, like bits of broken glass, rubber and steel left behind in a car accident. Inside the central nervous system (CNS), a region that includes the brain and spinal cord, it is the job of certain cells, called microglia, to clean up that cellular debris. Microglia have counterparts called…
For some cancers, initial treatment with chemotherapy brings positive, but only temporary, results: tumors shrink, but then rebound as the cancer becomes drug-resistant. This pattern of remission-resistance-relapse is particularly true for pancreatic cancer, an aggressive disease in which early success is often countered by eventual disease progression. To wit: The one-year relative survival rate…
Pathological infertility is a condition affecting roughly 7% of human males, and among those afflicted, 10-15% are thought to have a genetic cause. However, pinpointing the precise genes responsible for the condition has been difficult, due to the extensive number involved in generating and developing sperm cells. In a new paper appearing in Science Signaling, a Japanese team reports unravelling…
Babies born with congenital hyperinsulinism (CHI) are at risk of suffering from permanent brain damage and life-long disability. Yet some will go on to suffer more severely than others as a result of their disease profile, report the researchers in an article published in Frontiers in Endocrinology. The research team have found that it is possible to predict when and how the disease may affect…
A team of researchers across The University of Manchester have shown that a new class of drugs are able to stop ovarian cancer cells growing. The Cancer Research UK and Wellcome Trust funded study, published in the journal Cancer Cell, showed that the drugs, called PARG inhibitors, can kill ovarian cancer cells by targeting weaknesses within their ability to copy their DNA. The first-in-class…
Why do cancer cells react differently to treatments? Researchers from Mount Sinai and IBM have discovered a novel clue in explaining how cancer cells with identical genomes can respond differently to the same therapy. In a Nature Communications paper, researchers reveal for the first time that the number of mitochondria in a cell is, in great part, associated with how the cancer responds to drug…
Researchers at Karolinska Institutet have found that type IgG antibodies play an unexpected role in atherosclerosis. A study on mice shows that the antibodies stabilise the plaque that accumulates on the artery walls, which reduces the risk of it rupturing and causing a blood clot. It is hoped that the results, which are published in the journal Circulation, will eventually lead to improved…
Cancel the cheese omelet. There is sobering news for egg lovers who have been happily gobbling up their favorite breakfast since the 2015-2020 Dietary Guidelines for Americans no longer limited how much dietary cholesterol or how many eggs they could eat. A large, new Northwestern Medicine study reports adults who ate more eggs and dietary cholesterol had a significantly higher risk of…
A one-off operation that targets the nerves connected to the kidney has been found to maintain reduced blood pressure in hypertension patients for at least six months, according to the results of a clinical trial led in the UK by Queen Mary University of London and Barts Health NHS Trust, and supported by the National Institute for Health Research (NIHR). The study, published in the journal…
With a weak alternating electrical current sent through electrodes attached to the scalp, UNC School of Medicine researchers successfully targeted a naturally occurring electrical pattern in a specific part of the brain and markedly improved depression symptoms in about 70 percent of participants in a clinical study.
Research in the past several years has shown that children can outgrow a diagnosis of autism spectrum disorder (ASD), once considered a lifelong condition. In a new study, researchers at Albert Einstein College of Medicine and Montefiore Health System have found that the vast majority of such children still have difficulties that require therapeutic and educational support.
Having a genetic predisposition to high testosterone levels could play a role in the development of major heart problems in men, such as blood clots and heart failure, finds a study published by The BMJ. The findings may also have implications for men who take testosterone supplements to boost energy levels and sex drive. Some evidence suggests that genetically predicted (“endogenous”)…
