...eutic approaches. 'Admittedly, the ERK has so many tasks to do that there would probably be side-effects if it was impeded directly,' says Heinz Beck. 'However, the attempt could be made to protect the Kv4.2 channels from ERK attack, or reverse the chemical changes in the channels.'...Ecologist calls for creation of an international panel to assess human behavior
