Why do east Asian lung cancer patients respond better to chemotherapy than other ethnic groups? The answer could be useful in tailoring cancer treatments to individual patients.
"Genetic differences may help explain why so many Asian women who never smoked develop lung cancer," said Dr. Adi Gazdar, professor of pathology at UT Southwestern and senior author of a study appearing online today in Public Library of Science Medicine.
Proper formation of the proteins that power heart and skeletal muscle seems to rely on a precise concentration of a "chaperone" protein known as UNC-45, according to a new study.
This basic discovery may have important implications for understanding and eventually treating heart failure and muscle wasting elsewhere in the body resulting from burns, brain trauma, diabetes, cancer and the effects of aging, the senior author of the paper said. The finding resulted from experiments using tiny, genetically engineered worms at the University of Texas Medical Branch at Galveston (UTMB), and is reported in a paper featured on the cover of the April 23, 2007, issue of the Journal of Cell Biology.
Imagine a world where damaged organs in your body—kidneys, liver, heart—can be stimulated to heal themselves. Envision people tragically paralyzed whose injured spinal cords can be repaired. Think about individuals suffering from the debilitating effects of Parkinson’s or Alzheimer’s relieved of their symptoms – completely and permanently.
Scientists have discovered one of the reasons why bladder cancer is so much more prevalent in men than women: A molecular receptor or protein that is much more active in men than women plays a role in the development of the disease. The finding could open the door to new types of treatment with the disease.
In an article in the April 4 issue of the Journal of the National Cancer Institute, Chawnshang Chang, Ph.D., of the University of Rochester Medical Center and colleagues show that the androgen receptor, which is central to the action of testosterone and other hormones that are much more plentiful in men than women, appears to play a key role in the disease.
An effective way to fight leukemia might be to knock out a specific protein that protects cancer cells from dying, a new study shows.
The findings suggest that a drug that can block this "survival protein" might on its own be an effective therapy.
Strawberries are good for you, but serving them in daiquiri form may make them even healthier, scientists show.
While exploring ways to help keep strawberries fresh during storage, researchers from Thailand and the US discovered that treating the berries with alcohol led to an increase in antioxidant capacity and free radical scavenging activity within the fruit. While such a boost helped the berries resist decay, the same compounds would also be expected to make the strawberries healthier to eat.
Where there is cigarette smoking there is probably misuse of alcohol too, according to a study by Yale School of Medicine researchers in the Archives of Internal Medicine.
"This means cigarette smoking status can be used as a clinical indicator for alcohol misuse, which presents an opportunity for intervention," said the principal investigator, Sherry McKee, assistant professor of psychiatry.
Eur-eek!-a, they have found it!
Los Angeles: Just a short dispatch from the press room of the annual convention of the American Association for Cancer Research, which is celebrating its centennial this year. Considering the scale of the gathering--it fills the LA Convention Center--one would expect a basketball game to take place. But no. This is a convening of some of the most serious-minded people in the world, working on a disease that claims the lives of millions every year. It is, of course, an industry in itself--and that makes the trade show floor just as interesting ( and a bit less tedious) as the scientific workshops going on at the same time. And it is an industry largely built on the very tiny shoulders of our friend, mus musculus.
There's a lot of "Can X make you gay?" articles being written these days. This fellow says soy is making you gay
and even the New York Times wonders if you have a gay car.
Now a study from the University of Pittsburgh says that fish from Pittsburgh rivers contain substances that act like estrogen.
Estrogen. The female
Chemicals in cruciferous vegetables, such as broccoli, watercress, cabbage and cauliflower, appear to not only stop human prostate cancer cells from growing in mice but also may cut off the formation of blood vessels that "feed" tumors, says a University of Pittsburgh Cancer Institute study.
