Calcium channel links radiation to salivary gland problems in mice

Mice lacking the channel resisted early salivary gland dysfunction after irradiation; the authors linked its effects to cells entering a nondividing state.Mice lacking the channel resisted early salivary gland dysfunction after irradiation; the authors linked its effects to cells entering a nondividing state.
