A unique ribonuclease, active only in the presence of Ca2+, was present in lactating mammary gland and milk of the rat. This enzyme was absent from virgin-rat mammary gland and non-mammary tissues of lactating rats. The presence of moderate activity in differentiated mammary tumours, together with an increase in activity in normal tissue parelleling… CONTINUE READING
