A single protein helps the body keep watch over the Epstein-Barr virus
Some 90 percent of people are exposed to the Epstein Barr virus at some point in their life. Even though it is quickly cleared from the body, the virus can linger silently for years in small numbers of infected B cells. According to researchers, the immune system subdues the virus by watching for a single viral protein called LMP1.

Metastatic breast cancer hitches a free ride from the immune system
Inflammatory breast cancer (IBC) is the most lethal form of breast cancer . It spreads easily through the lymphatic and blood vessels, forming metastasis which can lead to multi-organ failure. New research demonstrates how IBC cells use IL-8, secreted as part of the anti-inflammatory response by a specific set of white blood cells (monocytes), to increase fibronectin expression.

Complex wiring of the nervous system may rely on a just a handful of genes and proteins
Researchers have discovered a startling feature of early brain development that helps to explain how complex neuron wiring patterns are programmed using just a handful of critical genes. The findings may help scientists develop new therapies for neurological disorders, such as amyotrophic lateral sclerosis, and provide insight into certain cancers.

Nanotube therapy takes aim at breast cancer stem cells
Researchers have again shown that injecting multiwalled carbon nanotubes (MWCNTs) into tumors and heating them with a quick, 30-second laser treatment can kill them.

DNA sequencing helps identify cancer cells for immune system attack
DNA sequences from tumor cells can be used to direct the immune system to attack cancer, according to scientists. The immune system relies on an intricate network of alarm bells, targets and safety brakes to determine when and what to attack. The new results suggest that scientists may now be able to combine DNA sequencing data with their knowledge of the triggers and targets that set off immune alarms to more precisely develop vaccines and other immunotherapies for cancer.

Scientists use old theory to discover new targets in fight against breast cancer
Reviving a theory first proposed in the late 1800s that the development of organs in the normal embryo and the development of cancers are related, scientists have studied organ development in mice to unravel how breast cancers, and perhaps other cancers, develop in people. Their findings provide new ways to predict and personalize the diagnosis and treatment of cancer.

Regular use of vitamin and mineral supplements could reduce the risk of colon cancer, study suggests
Could the use of vitamin and mineral supplements in a regular diet help to reduce the risk of colon cancer and protect against carcinogens? A study published in the Canadian Journal of Physiology and Pharmacology found that rats given regular multivitamin and mineral supplements showed a significantly lower risk of developing colon cancer when they were exposed to carcinogens.

New genetic subtype of lung cancer defined
Investigators have defined the role of a recently identified gene abnormality – rearrangements in the ROS1 gene – in a deadly form of lung cancer. ROS1-rearranged tumors represent one to two percent of non-small-cell lung cancers, the leading cause of cancer death in the US. The researchers also show that ROS1-driven tumors can be treated with crizotinib and describe the remarkable response of one patient to crizotinib treatment.

Visual nudge improves accuracy of mammogram readings
False negatives and positives plague the reading of mammograms, limiting their usefulness. Computer scientists have now shown that the accuracy of novice readers can be improved by nudging them visually to follow the scanpath of an expert radiologist. The “nudge” is a brief change in the brightness or warmth in the image in the peripheral field of view.
