Mammary nucleic acids and pituitary prolactin secretion during prolonged lactation in mice



Mammary nucleic acids and pituitary prolactin secretion during prolonged lactation in mice



Journal of Endocrinology 70(3): 389-395



Lactation was prolonged until 61 days by repeated renewal of litters every wk after day 12 in primiparous C3H/He strain mice. On days 12, 19, 40 and 61 of lactation, litters were removed for 5 h and after 1 h of resuckling the synthesis of DNA and RNA in the mammary gland was estimated by the incorporation of hymidine and ridine into mammary DNA and RNA in vitro respectively. Mammary nucleic acid content and pituitary and plasma levels of prolactin (PRL) were also assayed.
