Major gene study uncovers secrets of leukemia

... gene in this pathway could be accurately analyzed using this methodology," Downing said. The mutations identified in "PAX5," "EBF" and "Ikaros" are likely to directly contribute to this block in normal lymphocyte differentiation, according to Downing. These genes encode proteins called transcription f...

Arsenic in chicken feed may pose health risks to humans, C&EN reports

...y. A growing number of food suppliers have stopped using the compound, including the nation’s largest poultry producer, Tyson Foods, according to the article. Still, about 70 percent of the 9 billion broiler chickens produced annually in the U.S. are fed a diet containing roxarsone, the article points out....

The sturdier sex? -- Study by Pittsburgh scientists finds female stem cells work better

... an animal model of the disease, his laboratory is using stem cells to deliver dystrophin to muscles. In this study, Dr. Huard’s team injected female and male muscle-derived stem cells into dystrophic mice and then measured the cells?ability to regenerate dystrophin-expressing muscle fibers. They the...

Nanotextured implant materials: blending in, not fighting back
