Stimulation of luteinizing hormone secretion by food intake: evidence against a role for insulin.

abstract：:Experiments were carried out to characterize the prolactin stimulation of labeled uridine uptake into mammary gland explants which were initially preincubated for 2 days in medium containing insulin plus hydrocortisone. Prolactin was found to enhance labeled uridine uptake after 4 h but not after 2 h when uridine conc...
