For good and ill, immune response to cancer cuts both ways

For good and ill, immune response to cancer cuts both ways

The difference between an immune response that kills cancer cells and one that conversely stimulates tumor growth can be as narrow as a “double-edged sword,” report researchers at the University of California, San Diego School of Medicine in the April 7, 2014 online issue of the Proceedings of the National Academy of Sciences . “We have found that the intensity difference between an immune response that stimulates cancer and one that kills it may not be very much,” said principal investigator Ajit Varki, MD, Distinguished Professor of Medicine and Cellular and Molecular Medicine. “This may come as a surprise to researchers exploring two areas typically considered distinct: the role of the immune system in preventing and killing cancers and the role of chronic inflammation in stimulating cancers.

Mortality risks of being overweight or obese are underestimated

Mortality risks of being overweight or obese are underestimated

New research by Andrew Stokes, a doctoral student in demography and sociology in the School of Arts and Sciences at the University of Pennsylvania, suggests that many obesity studies substantially underestimate the mortality risks associated with excess weight in the United States. His study, “Using Maximum Weight to Redefine Body Mass Index Categories in Studies of The Mortality Risks of Obesity,” was published in the March issue of the open-access journal Population Health Metrics Continue reading

Well-known cancer gene NRAS produces 5 variants, study finds

A new study shows that a gene discovered 30 years ago and now known to play a fundamental role in cancer development produces five different gene variants (called isoforms), rather than just the one original form, as thought. Continue reading

Helium ions may provide superior, better-targeted treatment in pediatric radiotherapy, study suggests

Helium ions may provide superior, better-targeted treatment in pediatric radiotherapy, study suggests

For the first time, researchers have been able to demonstrate that the use of helium ions in radiation therapy could provide accurate treatment to tumours while helping to spare healthy organs. A treatment planning study to be presented at the ESTRO 33 congress today Sunday has been able to show that helium may have effects that are superior to radiotherapy using protons, themselves a considerable advance on conventional photon beam radiotherapy Continue reading

Self-healing engineered muscle grown in the laboratory

Biomedical engineers have grown living skeletal muscle that looks a lot like the real thing. It contracts powerfully and rapidly, integrates into mice quickly, and for the first time, demonstrates the ability to heal itself both inside the laboratory and inside an animal Continue reading
