Gene turn-off makes meek mice fearless

`Deactivating a specific gene transforms meek mice into daredevils, researchers have found. The team believe the research might one day enable people suffering from fear in the form of phobias or anxiety disorders, for example to be clinically treated.

The research found that mice lacking an active gene for the protein stathmin are not only more courageous, but are also slower to learn fear responses to pain-associated stimuli, says geneticist Gleb Shumyatsky, at Rutgers University in New Jersey, US.’
