The intestinal ecosystem is even more dynamic than previously thought, according to two studies by UT Southwestern Medical Center researchers published in the latest issue of Science. Taken together, these studies provide a new understanding of the unique intestinal environment and suggest new strategies for the prevention of inflammatory bowel disease (IBD) and viral infections, the researchers said. "Mammals have evolved ways to limit invasion by the naturally occurring bacteria that...

People who frequently use tanning beds may be spurred by an addictive neurological reward-and-reinforcement trigger, researchers at UT Southwestern Medical Center have found in a pilot study. This could explain why some people continue to use tanning beds despite the increased risk of developing melanoma, the most lethal form of skin cancer. The brain activity and corresponding blood flow tracked by UT Southwestern scientists involved in the study is similar to that seen in people addicted to...

A person's ability to battle viruses at the cellular level remarkably resembles the way deadly infectious agents called prions misfold and cluster native proteins to cause disease, UT Southwestern Medical Center researchers report. This study marks the first discovery of so-called "good" prion-like proteins in human cells and the first to find such proteins involved in innate immunity: the way the body recognizes and responds to threats from viruses or other external agents, said Dr. Zhijian...

UT Southwestern Medical Center researchers have narrowed the potential drug targets for advanced prostate cancer by demonstrating that late-stage tumors are driven by a different hormonal pathway than was thought previously. While testosterone is generally known to stimulate the growth of the disease, advanced prostate cancer that is resistant to standard hormonal therapy actually is driven by a pathway that circumvents the male hormone, said Dr. Nima Sharifi, assistant professor of internal...

Researchers at UT Southwestern Medical Center say there are at least 70 genetic mutations involved in the formation of colon cancer, far more than scientists previously thought. Based on the study, published in the July 2011 Cancer Research (Priority Reports), researchers are suggesting a new approach to colon cancer treatments targeting multiple genes and pathways simultaneously. Current cancer treatments target just one or two known cancer-driver genes believing this would be beneficial to...

Surgery and all its implications can be scary, especially so for pediatric patients and their parents who dread sometimes disfiguring scars. Now a UT Southwestern Medical Center urologist has developed a new "hidden" minimally invasive procedure that makes scarring virtually invisible yet is just as effective as more common surgical methods. "Currently used incisions, even with minimally invasive surgery, leave the child with up to three scars that are visible any time the abdomen is exposed....
