Animal lovers should be among the biggest supporters of animal medical research. For example, researchers at the University of Wisconsin have identified a protein that’s present in greater-than-normal quantities in dogs with osteosarcoma, a type of bone cancer that afflicts more than 10,000 dogs a year. Eight in ten of these dogs don’t live more than a year after their diagnosis. Future research could determine whether the protein actually causes tumor production – and which genes are responsible for ordering higher concentrations of the protein.
