Powerful whole-species gene editing tool fails first tests in mice | New Scientist
Cooper found that in mice the copying process worked only 70 per cent of the time at best. What’s more, when the copying process failed it induced mutations in the target sequence, meaning that resistance to the gene drive could evolve very quickly and halt the spread of the drive.

Resistance is inevitable
A press release about the study hails these results as “Successful gene drive developed in lab mice”. Yet what Cooper tested was not a self-replicating gene drive but the separated components of a drive. This was done both for safety and convenience.

So it’s neither a gene drive nor successful in the sense of potentially providing a practical method for controlling mammalian pests. But it’s early days still and researchers could well find ways to dramatically improve the copying efficiency in mammals and to prevent resistance developing. “We would need to improve both,” says Cooper.

Meanwhile, the work does have potential benefits. The approach Cooper and her colleagues developed could provide a big boost to efforts to understand the causes of disease.

Researchers trying to work out what effect gene variants have on health often to need combine different traits in a single strain of animals. At present this can be prohibitively expensive, because as the number of traits to be combined goes up, says Cooper, the number of mice that have to be created via cross-breeding rises exponentially.

Using the gene drive concept – or “active genetics” as some call it – could change the odds and make this far more affordable.

Other groups have developed successful gene drives that might one day be used to eliminate the mosquitoes that carry malaria. Last year a team led by Andrea Crisanti of Imperial College London wiped out mosquito populations in small cages in a lab using a gene drive. The team will now carry out tests in much bigger cages in Italy designed to mimic conditions in the tropics.
