Data from a clinical trial at the Virginia-Maryland College of Veterinary Medicine at Virginia Tech to treat brain tumors in dogs may eventually be used to help humans. The study is trying to determine the safety of a new chemotherapeutic drug and drug delivery method in the treatment of brain tumors in dogs. It’s […]

High cholesterol levels have been associated with breast cancer spreading to other sites in the body, but doctors and researchers don’t know the cause for the link. A new study by University of Illinois researchers found that the culprit is a byproduct of cholesterol metabolism that acts on specific immune cells so […]

Many approved cancer therapies target a protein called epidermal growth factor receptor (EGFR) that regulates many crucial cellular processes and can speed the proliferation of tumor cells. Yale Cancer Center scientists now have made a fundamental discovery about EGFR signaling, reported in the journal Cell, that may open the potential for new types […]

Melanoma, a cancer of skin pigment cells called melanocytes, will strike an estimated 87,110 people in the U.S. in 2017, according to the Centers for Disease Control and Prevention. A fraction of those melanomas come from pre-existing moles, but the majority of them come from sources unknown – until now. […]

Scientists have had positive results from a laboratory-based study using a well-known alcohol aversion drug to try to combat chemotherapy resistance in the most common type of lung cancer, non-small cell lung cancer (NSCLC). The findings from the scientists at Trinity College Dublin and St James’s Hospital have been published […]

Researchers from Trinity College Dublin have made a discovery around treatment-resistant breast cancer that may turn the phrase, ‘don’t shoot the messenger’, on its head. The scientists have found that cell to cell messengers released by cancer cells which are not responding to treatment, can negatively affect the body’s immune […]

New King’s College London research reveals how blood inflammation affects the birth and death of brain cells, which could offer new treatment targets for antidepressants. Mounting evidence points to high levels of inflammation as an important biological abnormality leading to depression in at least one third of patients. However, this […]

UCLA scientists have discovered a potential combination treatment for glioblastoma, the deadliest form of brain cancer in adults. The three-year study led by David Nathanson, a member of UCLA’s Jonsson Comprehensive Cancer Center, found that the drug combination tested in mice disrupts and exploits glucose intake, essentially cutting off the […]

An international team of researchers at University of California San Diego School of Medicine and Moores Cancer Center, with colleagues at Sun Yet-sun University Cancer Center and other collaborating institutions, have developed a new diagnostic and prognosis method for early detection of hepatocellular carcinoma (HCC), based on a simple blood […]

  An international team led by scientists at the National Institutes of Health is the first to discover a new way that cells fix an important and dangerous type of DNA damage known as a DNA-protein crosslink (DPC). The researchers found that a protein named ZATT can eliminate DPCs with […]

You would not expect diamonds to have anything to do with cancer treatment. But they can actually they improve patients’ chances of survival. “Using traditional techniques, it’s almost impossible to determine whether a cancer treatment has been 100 per cent or 99.9 per cent effective. The difference can have major […]

A team of researchers at Cardiff University’s Schools of Pharmacy and Pharmaceutical Sciences, Medicine, and Biosciences, together with the Basque Foundation for Science in Spain, has discovered a new way of tagging these nanobodies that are made naturally by cells. Exosomes play an important role in the way in which […]

Researchers from the Aboobaker lab in the Department of Zoology used the worms (planarians) which are known for their ability to regenerate their tissues and organs repeatedly. This process is enabled by their stem cells, which constantly divide to make new cells. Cell migration – or the movement of cells […]

Proteins and drugs are often attached to lipids to promote crystallization or ensure delivery to targeted tissues within the body, but only the smallest proteins and molecules fit within these fat structures. A new study reveals a lipid structure that can support much larger proteins and molecules than before, potentially […]

UCLA biophysicists have developed a new method to rapidly determine a single cell’s stiffness and size — which could ultimately lead to improved treatments for cancer and other diseases. The method allows researchers to make standardized measurements of single cells, determine each cell’s stiffness and assign it a number, generally […]

New research will seek to understand why people who are HIV positive are more susceptible to a progressive cerebrovascular disease that can ultimately give rise to dementia.  One of the goals of the research is to identify new ways to prevent the blockages that occur in blood vessels and cause […]

The immune system is contantly performing surveillance to detect foreign organisms that might do harm. But pathogens, for their part, have evolved a number of strategies to evade this detection, such as secreting proteins that hinder a host’s ability to mount an immune response. In a new study, a team […]

A new collaboration between two UC Santa Barbara labs explores the underlying molecular mechanism of a remarkable process called anastasis, a Greek word meaning “rising to life.” Building on earlier work showing that cells can recover from the brink of death, the new study demonstrates that anastasis is an active […]

Biological clocks are ticking everywhere throughout our body. They trigger the release of the hormone melatonin during sleep, leading to the secretion of digestive enzymes at lunchtime or keep us awake at the busiest moments of the day. A “master clock” in the brain synchronises all the subsidiary ones in […]

A new cancer treatment with the ability to normalise tumour blood vessels and boost the body’s immune system has been developed by researchers from The University of Western Australia and the Harry Perkins Institute of Medical Research. Many tumours can become resistant to the body’s immune system by creating a […]

In a first-of-its-kind study, University of California San Diego School of Medicine researchers report that a blood sample, or liquid biopsy, can reveal which patients will respond to checkpoint inhibitor-based immunotherapies. “We can help predict response to immunotherapy by measuring the number of mutations in circulating tumor DNA using a […]

In a new study, Yale researchers have described how nervous systems and immune systems talk to each other to control metabolism and inflammation. Their finding furthers scientists’ understanding of why older adults fail to burn stored belly fat, which raises the risk of chronic disease. The study also points to […]

Like a string of pearls, the spine is made of a series of similar vertebrae. A so-called segmentation clock creates this repetitive arrangement in developing embryos: Each time the clock ticks, a vertebra starts to form. In a paper published Sept. 21 in Cell, Harvard Medical School genetics professor Olivier Pourquié—whose lab […]

Cancers driven by mutations in the KRAS gene are among the most deadly. For decades, researchers have tried unsuccessfully to directly target mutant KRAS proteins as a means to treat tumors. Instead of targeting mutant KRAS itself, researchers at University of California San Diego School of Medicine are now looking […]
