Genetic Retrofitting? (Score 1)

Will we be able to benefit directly from this research in the form of a 'cure' along similar lines for humans? Or are we merely planning on breeding the mice to develop other forms of treatments which won't require human genetic retrofitting? It sounds rather wonderful, really, but cancer-free mice that had to be bred in the lab via eugenic mousemaking seems to have limited application if the only way to make humans immune to cancers would be to genetically engineer them that way. Would we continue to be human at that point, or would we finally have crossed over to Homo sapiens superiori. ? I'm just wondering the "What next?" implications this has.
