Fish no exception to trend in marine-organism disease

...: "This is the first quantitative study to provide solid evidence that rates of disease do seem to be increasing in the ocean. It has been hard to tell if disease is increasing because we didn't have proper baselines. It's been much tougher to understand the frequency of marine disease than it is to monito...

DNA research highlights prostate cancer mechanisms

Tadpoles and tumors

...w that FAP is present in about 90 percent of human solid malignancies, so that makes this protein a target well worth pursuing," Cheng said. "Antibodies have an inherent advantage in that they can specifically target FAP and not other proteins. Although the antibody we have studied so far has had only mo...

Awards honor Alt's three decades of genetic cancer research

...in mice, they get all sorts of cancers lymphomas, solid tumors, you name it," Alt says. Interestingly, simply reducing H2AX activity is enough to cause genomic instability. "You can't just think that a tumor suppressor gene has to be completely mutated or gone to contribute to cancer," he says. "We need...
