Effect of lysine on survival of AKR leukemic mice.

The effect of lysine/arginine antagonism on the survival of mice with virally - produced leukemia was investigated by feeding AKR mice diets low in arginine with varying amounts of lysine. Over a period of one year, a diet containing 5.6% lysine and no arginine resulted in a significantly lower mortality than one with lower levels of lysine, plus arginine.
