[Prolactin and serotonin].

ABSTRACT

An overview of the results of studies on prolactin (PRL) is given. The molecular and genetic characteristics of PRL and its receptor (PRLR) are presented. The PRLR polymorphism in patients with tumors of the breast is described. Synthesized analogues of human PRL inhibited its peripheral effects. The vegetative nervous system modulate PRL secretion. PRL is a risk factor for breast and prostate cancer. The signaling mechanisms of PRL and its possible clinical use in therapy of breast cancer are characterized.
