Women with inflammatory breast cancer — a rare, highly aggressive form of the disease — are living about twice as long after diagnosis than their counterparts in the mid-to-late 1970s, according to a new University of Michigan Rogel Cancer Center study. The researchers found that from 1973-1977, patients diagnosed with inflammatory breast […]

Lower levels of the vitamin negatively impacted balance and coordination. When it comes to vitamin D, most adults exhibit either frank deficiency, which results in clear clinical symptoms, or insufficiency, which often goes undetected. But how that insufficiency impacts physical health and the vulnerability of older adults to frailty as […]

In response to certain types of injury and inflammation, many organs produce tough scar tissue, a process called fibrosis, which can ultimately lead to organ failure or even death. Fibrosis is such a central component of so many different diseases – from cardiovascular disease to kidney failure – that scientists […]

Oregon State University scientists have developed a method that could potentially predict the cancer-causing potential of chemicals released into the air during wildfires and fossil fuel combustion. The research, which was recently published in the journal Toxicology in Vitro, was conducted as a part of the OSU Superfund Research Program.  The findings […]

A greater density of cells in a key reward centre of the brain is associated with obesity in children and predicts future weight gain, a new Yale-led study finds. The findings, published in the Proceedings of the National Academy of Sciences, suggest that a greater concentration of specialized cells in […]

The white blood cell TH17 helps the immune system fight infection by promoting inflammation. But it can be too much of a good thing: Excessive inflammation from TH17 overload has been tied to autoimmune disorders, such as inflammatory bowel disease (IBD) and arthritis. Researchers led by Hening Lin, professor of chemistry […]

A University of Oregon-initiated project using tiny roundworms has identified defects tied to infertility that result when too much DNA is exchanged in the formation of sperm and eggs. The fundamental research, detailed in a paper placed online in PLOS Genetics, probed what happens when too many DNA exchanges, called […]

University of Alberta chemists have developed new tools for studying the human immune system that lay the foundation for research that could improve understanding of cancer and neurodegenerative diseases such as Alzheimer’s. “Our lab studies sugar-binding receptors called Siglecs that control cells in our immune system,” explained Matthew Macauley, assistant professor […]

Cancer vaccines have shown promise in treating certain tumors, such as melanoma. But such vaccines have limitations. They often target normal proteins that may be more abundant in the tumor but also are present in healthy tissue, which can lead to off-target effects that cause autoimmune disorders and also reduce […]

A study lead by KI researcher and SciLifeLab Fellow Simon Elsässer elucidates a new flavour of heterochromatin, used by embryonic stem cells to silence ‘parasitic’ DNA-elements within the context of their highly dynamic pluripotent chromatin. The study was recently published in Nature Communications. So-called transposons are abundant DNA-elements found in […]

Electrical engineers, computer scientists and biomedical engineers at the University of California, Irvine have created a new lab-on-a-chip that can help study tumor heterogeneity to reduce resistance to cancer therapies.
