In one cancer therapy, two halves are safer than a whole

Splitting one type of cancer drug in half and delivering the pieces separately to cancer cells could reduce life-threatening side effects and protect healthy, non-cancerous cells, a new study suggests. The study, published in the Proceedings of the National Academy of Sciences, suggests that splitting immunotoxins into two inactive and […]

Accumulating extra genome copies may protect fly brain cells during aging

Scientists at the University of Michigan have discovered a novel anti-aging defense in the brain cells of adult fruit flies: producing extra copies of the genome. The findings could help explain how the brain, which rarely produces new cells, is able to cope with the accumulation of cell damage over […]

Research team pairs 3D bioprinting and computer modeling to examine cancer spread in blood vessels

Lawrence Livermore National Laboratory (LLNL) scientists have paired 3D-printed, living human brain vasculature with advanced computational flow simulations to better understand tumor cell attachment to blood vessels, the first step in secondary tumor formation during cancer metastasis. The unique approach, developed with outside collaborators, lays the foundation for developing a predictive […]

Researchers discover cell communication mechanism that drives cancer adaptation

Collaborative Cancer Research UK-funded studies from University of Oxford researchers have uncovered a new mechanism by which cancer cells adapt to the stresses they encounter as they grow and respond to therapies. This mechanism involves cells releasing small vesicles, known as exosomes. These contain complex mixtures of proteins, RNAs and […]

Fresh biopsies can improve development of cancer drugs

COVID-19 didn’t make all other diseases disappear. Cancer is still killing people like before and scientists are still trying to find new ways to treat it. Now researchers from the University of Queensland found that fresh tumour biopsies respond differently to medicine than the  tissue cultures traditionally used. This could […]

Gene therapy could potentially reverse memory loss from Alzheimer's in humans

Researchers from Macquarie University have discovered a world-first new treatment that reverses the effects of memory loss associated with Alzheimer’s disease in a study of mice with advanced dementia. The research, co-led by two brothers, Dr Arne Ittner and Professor Lars Ittner, from Macquarie University Dementia Research Centre, builds on their work […]

Leading-edge Technology Unmasks Protein Linked to Parkinson’s Disease

An elusive protein that many consider the key of fully understanding the causes of genetic Parkinson’s disease has come much more clearly into focus. Impacting millions around the world, Parkinson’s is a neurological disorder that progressively attacks motor functions, leading to lasting damage in movement and coordination, among other areas. […]

Excessive Fructose Consumption May Cause a Leaky Gut, Leading to Fatty Liver Disease

Excessive consumption of fructose — a sweetener ubiquitous in the American diet — can result in non-alcoholic fatty liver disease (NAFLD), which is comparably abundant in the United States. But contrary to previous understanding, researchers at University of California San Diego School of Medicine report that fructose only adversely affects […]

Inflammatory Bowel Disease Linked to an Immune Cell Run Amok

Inflammatory bowel disease (IBD) is a group of intestinal disorders affecting an estimated six to eight million people worldwide. Although there are many treatments for IBD, a number of patients fail to respond long-term, leaving those afflicted with a host of chronic issues, from abdominal pain and cramping to frequent, […]

Uncontrolled ‘cAMP’ Helps Spark Rare Liver Cancer

Since humans first controlled fire, they have camped around it to circulate information, signaling each other when something approaches. Metaphorically, certain molecules have been carrying information around our cells to help regulate bodily functions as needed. One such molecule, called cyclic AMP or “cAMP,” presumably travels freely inside cells managing […]

Fresh tumour biopsies in world-first technique for cancer treatments

An innovative technique to improve cancer treatments using tumour biopsies less than 30 minutes after they’re taken has been developed at The University of Queensland. The ‘Drug uptake in ex Vivo tumours’ technique was developed after researchers found fresh patient tumour biopsies responded differently to treatments than the tissue cultures […]

Newly discovered ‘support system’ for axons suggests a novel therapeutic target for neurodegenerative diseases

Axons are long, finger-like projections of neurons that transmit critical signals throughout the nervous system. But because they are fragile, they are often among the first casualties of certain neurodegenerative diseases, causing symptoms such as muscle weakness or numbness of limbs. New research from the University at Buffalo reveals that […]

Detecting pancreatic cancer at treatable stages

Pancreatic cancer is rarely detected at its early stages because symptoms often do not present themselves until after the cancer has progressed. By then, invasive procedures such as surgery, chemotherapy or radiation are often needed to treat the cancer. Now, researchers at the University of Missouri’s College of Veterinary Medicine […]

Protein ‘chameleon’ colors long-term memory

A chameleonlike protein in neurons can change its mind, and in the process change our brains. Scientists at Rice University and the University of Texas Health Science Center at Houston (UTHealth) uncovered new clues in the protein CPEB3 as part of their dogged pursuit of the mechanism that allows humans to have […]

A simple blood test could predict the success of immunotherapy

Immunotherapy is a promising technology for cancer treatment. Essentially, body’s own immune system is taught how to recognize cancer cells and kill them. When other treatments have failed, immunotherapy can still shrink tumours and prolong survival. However, it doesn’t work for everyone – how to predict which patients could benefit […]
