The mouse is a mouse is a mouse -- unless you're a scientist. For many researchers, the genetically engineered mouse is one of the most powerful research tools of the 20th century. A two-day seminar May 8-9 sponsored by University Extension at UC Davis is bringing together UC scientists and the biotechnology community in California to discuss the best ways and scientific methods to utilize this important animal model. "The Genetically Altered Mouse: A Practical Guide to Development and Analysis" consists of lectures and discussions that will examine the mouse as a genetic animal at both the theoretical and applied levels. The seminar will teach research assistants and lab and colony managers to analyze the mouse as an entire research system, bringing together various aspects of science including genetic manipulation, reproductive biology and breeding management, use of the genetically altered mouse in specific research programs and methods for interpreting results more accurately. "The ability to manipulate the genetic makeup of the mouse has allowed us to further our understanding of basic biological science as well as to pioneer discoveries in the treatment of human disease," says Jeff Roberts, coordinator of the seminar and assistant director of the California Regional Primate Research Center at UC Davis. The seminar takes place on campus. The fee for participants is $300.
