Researchers Create First Targeted Knockout Rats Using Zinc Finger Nuclease Technology

In a paper published in the July 24, 2009 issue of Science, researchers describe the novel application of ZFNs to generate rats with permanent, heritable gene mutations, paving the way for the development of novel genetically modified animal models of human disease. ZFN technology will make the generation of such animals faster and will create new opportunities in species other than mice.


"Until now, rat geneticists lacked a viable technique for 'knocking out,' or mutating, specific genes to understand their function," said Howard Jacob, Ph.D. Director of the Human and Molecular Genetics Center at the Medical College of Wisconsin. "This study demonstrates that ZFN technology bypasses the current need to conduct cumbersome experiments involving nuclear transfer (cloning) or embryonic stem cells and allows rapid creation of new animal models."

Genetic clue to brain cancer risk

UK and US scientists identified genetic indicators that someone is at greater risk of developing a glioma - which accounts for 50% of all brain. 34 SNPs linked with glioma.
