Sasha is still spunky at 12 - a white dog with a smattering of black, floppy ears and a sweet face. Even after she lost her right foreleg to bone cancer, her owners said, she could jump and catch a Frisbee. Doctors at Penn's School of Veterinary Medicine pumped a modified listeria bacteria into her bloodstream, hoping to push her immune system to kill remaining cancer cells. If the treatment works, it is likely to be tested next on humans with this type of bone cancer, called osteosarcoma.

In his June 12, 2012 article, Rep. Roscoe Bartlett (R-Md.) argues that ending experimentation on chimpanzees is the right choice. While Rep. Bartlett is entitled to his views, we believe strongly that the passage of S. 810/H.R. 1513, the Great Ape Protection and Cost Savings Act (GAPCSA), which he introduced, would have a devastating impact upon the advancement of medicine and human health.

The ability to control whether certain stem cells ultimately become bone cells holds great promise for regenerative medicine and potential therapies aimed at treating metabolic bone diseases. Now, UCLA School of Dentistry professor and leading cancer scientist Dr. Cun-Yu Wang and his research team have made a significant breakthrough in that direction. The scientists have discovered two key epigenetic regulating genes - using mice- that govern the cell-fate determination of human bone marrow stem cells.

New vaccines promote weight loss. A new study, published in BioMed Central’s open access journal, Journal of Animal Science and Biotechnology, assesses the effectiveness of two somatostatin vaccinations, JH17 and JH18, in reducing weight gain and increasing weight loss in mice.

Researchers have created the first mouse model demonstrating the role of a cancer promoting gene, Astrocyte elevated gene-1 (AEG-1), in hepatocellular carcinoma, or liver cancer. The mouse model represents a critical step in understanding the molecular mechanisms of liver cancer progression and could lead to novel therapies for the disease.

Researchers at Virginia Commonwealth University (VCU) Massey Cancer Center's Bone Marrow Transplant Program have demonstrated that the use of antibodies derived from rabbits can improve the survival and relapse outcomes of leukemia and myelodysplasia patients receiving a stem cell transplant from an unrelated donor.

It's not often that the Department of Homeland Security makes it into a science blog, but this is an unusual week. The department announced this week that it has developed the first vaccine for foot-and-mouth disease that can be manufactured and licensed in the United States and that could be used in the event of an outbreak of the disease in this country.

Scientists at Texas Biomed have developed the laboratory opossum as a new animal model to study the most common liver disease in the nation – afflicting up to 15 million Americans – and for which there is no cure.

The human airway is a pretty inhospitable place for microbes. There are numerous immune defense mechanisms poised to kill or remove inhaled bacteria before they can cause problems. But cystic fibrosis disrupts these defenses, leaving patients particularly susceptible to airway infection, which is the major cause of disease and death in cystic fibrosis. Using a unique animal model of cystic fibrosis, pigs, a team of scientists from the University of Iowa has discovered a difference between healthy airways and airways affected by cystic fibrosis that leads to reduced bacterial killing in cystic fibrosis airways.

University of British Columbia scientists, in collaboration with an industry partner, have successfully reversed diabetes in mice using stem cells, paving the way for a breakthrough treatment for a disease that affects nearly one in four Canadians.

UCLA researchers have discovered that a diet enriched with a popular omega-3 fatty acid and an ingredient in curry spice helps to preserve walking ability in rats that have experienced damage to their spinal cords.

As the world fights obesity at the human level, scientists at the University of Michigan and their colleagues have made a surprising finding at the microscopic level that could help fuel that fight.Their work, using mice, helps explain why fat-storing cells get fatter, and burn fat slower, as obesity sets in. If their findings from mice can be shown to apply to humans, they may provide a new target for obesity-fighting drugs.
