Gene Deficiency is a Protective Barrier to Obesity (7/2/2007)

A search for the molecular clues of longevity has taken Mayo Clinic researchers down another path that could explain why some people who consume excessive calories don't gain weight. The study, which was done in laboratory mouse models, points to the absence of a gene called CD38. When absent, the gene prevented mice on high-fat diets from gaining weight, but when present, the mice became obese. ...> Full Article

Antibodies Protect Mice from Developing Respiratory Tularemia (6/29/2007)

The respiratory form of tularemia, a potentially serious bacterial disease, is a significant public health concern because it is highly infectious, it has a high mortality rate if untreated, and it could be introduced into a population in an intentional act of bioterror. Though much research is focused on developing drugs and vaccines targeted to the bacterium that causes tularemia, Francisella tularensis, little is known about the role that antibodies play in protecting against infection. ...> Full Article

Researchers Find Gene Is Needed For Healthy Sperm (6/29/2007)

Human sperm cells travel up to 6 meters in their transit from testes to penis, and most of that journey occurs in the epididymis, a tightly coiled tube that primes the cells for their ultimate task: fertilization. In a paper released this week in the Proceedings of the National Academy of Sciences, researchers at the University of Illinois report that they have discovered a gene – and related mechanism – essential to the embryonic development of the epididymis. ...> Full Article
