Gene-regulating enzyme is also a target for anti-depressive drugs

...rs of that second enzyme are currently in clinical trails as cancer therapies. "Might particular monoamine oxidase inhibitors, currently used primarily to treat depression, have anti-cancer activity too?" Shiekhattar says. "Our findings indicate this could be the case, and we are currently screening these d...
