Every 12 minutes, someone in the United States dies of pancreatic cancer, which is often diagnosed late, spreads rapidly and has a five-year survival rate at approximately 10 percent. Treatment may involve radiation, surgery and chemotherapy, though often the cancer becomes resistant to drugs. Researchers at University of California San […]

Bioengineers at the University of California San Diego and San Diego State University have discovered a key feature that allows cancer cells to break from typical cell behavior and migrate away from the stiffer tissue in a tumor, shedding light on the process of metastasis and offering possible new targets […]

A gene therapy for chronic pain could offer a safer, non-addictive alternative to opioids. Researchers at the University of California San Diego developed the new therapy, which works by temporarily repressing a gene involved in sensing pain. It increased pain tolerance in mice, lowered their sensitivity to pain and provided […]

For certain blood cancers, such as acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), deciding whether patients need an aggressive treatment typically hinges on a set of lab tests to identify genetic changes. Some of these tests rely on technology that was invented more than 60 years ago and has […]

Eating is a dangerous business. Naturally occurring toxins in food and potentially harmful foodborne microbes can do a number on our intestines, leading to repeated minor injuries. In healthy people, such damage typically heals in a day or two. But in people with Crohn’s disease, the wounds fester, causing abdominal […]

In response to brain injury, neural stem cells cluster and migrate to the site of injury. The clustering is key – without it, the cells don’t travel. But what causes it? To investigate, Yale researchers created a 3-D model of the brain’s workings. The results of the study, led by […]

Scientists at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study, published in Nature, also shows that movement-induced stimulation is required for the maintenance of this niche, […]
