Drugs targeting tumour metabolism will not stop our ‘Natural Killer’ cells

Scientists have just made an important discovery as to how cancer-targeting ‘Natural Killer’ (NK) cells are fuelled in the body, which has significant implications for related therapies. They found that glutamine – vital for making the energy that fuels tumour cell growth – is not an important fuel for making […]

Genome-editing tool could increase cancer risk in cells, say researchers

More research needs to be done to understand whether CRISPR-Cas9 – molecular ‘scissors’ that make gene editing a possibility – may inadvertently increase cancer risk in cells, according to researchers from the University of Cambridge and the Karolinska Institutet. The team, led by Professor Jussi Taipale, now at the Department […]

Targeting strategy may open door to better cancer drug delivery

Bioengineers may be able to use the unique mechanical properties of diseased cells, such as metastatic cancer cells, to help improve delivery of drug treatments to the targeted cells, according to a team of researchers at Penn State. Many labs around the world are developing nanoparticle-based, drug delivery systems to […]

Camouflaged nanoparticles used to deliver killer protein to cancer

A biomimetic nanosystem can deliver therapeutic proteins to selectively target cancerous tumors, according to a team of Penn State researchers. Using a protein toxin called gelonin from a plant found in the Himalayan mountains, the researchers caged the proteins in self-assembled metal-organic framework (MOF) nanoparticles to protect them from the […]

Greater Levels of Vitamin D Associated with Decreasing Risk of Breast Cancer

Researchers at University of California San Diego School of Medicine suggest higher levels of vitamin D are associated with decreasing risk of breast cancer. Their epidemiological study is published in the journal PLOS ONE, in collaboration with Creighton University, Medical University of South Carolina and GrassrootsHealth, an Encinitas-based nonprofit organization that […]

Gene therapy restores hand function after spinal cord injury in rats

Researchers at King’s College London and the Netherlands Institute for Neuroscience have shown that rats with spinal cord injuries can re-learn skilled hand movements after being treated with a gene therapy. People with spinal cord injury often lose the ability to perform everyday actions that require coordinated hand movements, such as […]

Fetal T cells are first responders to infection in adults

Cornell researchers have discovered there is a division of labor among immune cells that fight invading pathogens in the body. The study, published in the journal Cell, finds for the first time that fetal immune cells are present in adults and have specialized roles during infection. In fact, the first immune […]

New Gene Therapy Heals Spinal Cord Injuries in Mice

Rats with spinal cord injuries regained the use of their limbs after receiving a new gene therapy which helps mend damaged nerves in the spine. The new therapy works by inducing cells to produce an enzyme called chondroitinase which breaks down the thick scar tissue surrounding the site of injury, […]

Genome-editing tool could increase cancer risk

CRISPR-Cas9 is a molecular machine first discovered in bacteria that can be programmed to go to an exact place in the genome, where it cuts the DNA. These precise ‘molecular scissors’ can be used to correct faulty pieces of DNA and are currently being used in clinical trials for cancer […]

Antibody Blocks Inflammation, Protects Mice from Hardened Arteries and Liver Disease

Researchers at University of California San Diego School of Medicine discovered that they can block inflammation in mice with a naturally occurring antibody that binds oxidized phospholipids (OxPL), molecules on cell surfaces that get modified by inflammation. Even while on a high-fat diet, the antibody protected the mice from arterial […]

University of Tokyo's RCAST, Fujitsu, and Kowa Successfully Create Promising New Compounds to Fight Drug-Resistant Cancer

The University of Tokyo's Research Center for Advanced Science and Technology (RCAST), Fujitsu Limited, and Kowa Company Ltd. today announced that using IT-based drug discovery technologies, which entails computer-based virtual design and evaluation, they have successfully created new small molecule compounds that can inhibit cancer-causing “target proteins,” and that demonstrate […]

Genes linked to Alzheimer’s contribute to damage in different ways

Multiple genes are implicated in Alzheimer’s disease. Some are linked to early-onset Alzheimer’s, a condition that develops in one’s 30s, 40s and 50s, while others are associated with the more common late-onset form of the disease. Eventually, all Alzheimer’s patients develop dementia, and their brain cells die. But not all […]

The Making of a Brain

The cerebral cortex—the brain’s epicenter of high-level cognitive functions, such as memory formation, attention, thought, language and consciousness—has fascinated neuroscientists for centuries. Scientists have long known that this command center is organized into six distinct regions, or layers, but how this complex organization arises during development has remained largely a mystery. […]

Male guppies grow larger brains in response to predator exposure

Male guppies exposed to predators in the wild or in captivity have heavier brains than those living in relatively predator-free conditions, according to new research published in the journal Functional Ecology. Behavioural ecologists at McGill University in Montreal sampled guppies from two rivers in northern Trinidad. In each river, guppies live […]

AIDS and aging focus of research study

When the general public thinks of HIV, they do not think of a neurological disease, yet people living with HIV infection know they need to worry about their brain health. Untreated, HIV can cause severe dementia. Even with good control of the infection, a third or more of patients have […]

Laser technology provides detailed images of skin cancer

The first patients are expected to benefit from the new improved images in 2018. The project revolves around infrared light and finding the ideal wavelengths. Optical crystal fibres and laser technology. And shrinking a laser source that roughly fills two offices into shoebox-sized device. It draws on extensive knowledge of […]

Magnetic contrast agent behind clear MRI images

For decades, MRI scans have delivered stunningly beautiful images of the body’s anatomy. It is now possible to use MRI imaging at cellular level to observe cell metabolism. This is particularly useful in cancer treatment. With the help of a new technology, doctors may be able to determine on the […]

Diabetes results from a breakdown of epigenetic control

Diabetes affects more than 400 million individuals worldwide. In what is becoming a paradigm shift, researchers have begun to find that the disease may result in part through pancreatic beta cells losing their functional identity and shutting down their ability to release the blood sugar-lowering hormone, insulin. Researchers from the […]

Biomaterial Particles Educate Immune System to Accept Transplanted Islets

By instructing key immune system cells to accept transplanted insulin-producing islets, researchers have opened a potentially new pathway for treating type 1 diabetes. If the approach is ultimately successful in humans, it could allow type 1 diabetes to be treated without the long-term complications of immune system suppression. The technique, […]

Lipid molecules can be used for cancer growth

Tumour growth and spread rely on angiogenesis, a process of growing new blood vessels that supply the cancer cells with nutrients and hormones, including glucose (sugar). Treatment with antiangiogenic drugs reduces the number of blood vessels in the tumour as well as the blood glucose supply. Many such drugs have […]

The secret to longevity is in the microbiome and the gut

You are what you eat. Or so the saying goes. Science now tells us that we are what the bacteria living in our intestinal tract eat and this could have an influence on how well we age. Building on this, McGill University scientists fed fruit flies with a combination of […]
