Prolactin actions.
Molecular genetics and other contemporary approaches have contributed to a better understanding of prolactin (PRL) actions at the cellular and organismal levels. In this review, several advances in knowledge of PRL actions are highlighted. Special emphasis is paid to areas of progress with consequences for understanding of human PRL actions. The impacts of these advances on future research prio...
متن کاملProlactin receptor signal transduction pathways and actions determined in prolactin receptor knockout mice.
Prolactin-receptor-deficient mice are a good model in which to study the various actions of prolactin. Female homozygous knockout mice are completely infertile and show a lack of mammary development, while hemizogotes are unable to lactate following their first pregnancy. Male and female homozygotes have markedly elevated serum prolactin levels, and in some instances pituitary hyperplasia is pr...
متن کاملImmunobiological actions of antiserum to ovine prolactin in mice.
Neutralization of pituitary prolactin by the administration of antiserum to prolactin in the mouse selectively blocked the pro-oestrous stage of the oestrous cycle and inhibited ovulation in normal cyclic mice. In pseudopregnant mice, the antiserum shortened the duration of pseudopregnancy. Failure of the antiserum to affect uterine cell division, blastocyst implantation and pregnancy suggests ...
متن کاملActions of angiotensin II and dopamine in the medial preoptic area on prolactin secretion.
Dopamine (DA) is known as a primary regulator of prolactin secretion (PRL) and angiotensin II (Ang II) has been recognized as one brain inhibitory factor of this secretion. In this work, estrogen-primed or unprimed ovariectomized rats were submitted to the microinjection of saline or Ang II after previous microinjection of saline or of DA antagonist (haloperidol, sulpiride or SCH) both in the m...
متن کاملActions of Prolactin in the Brain: From Physiological Adaptations to Stress and Neurogenesis to Psychopathology
Prolactin (PRL) is one of the most versatile hormones known. It is considered an adaptive hormone due to the key roles it plays in the modulation of the stress response and during pregnancy and lactation. Within the brain, PRL acts as a neuropeptide to promote physiological responses related to reproduction, stress adaptation, neurogenesis, and neuroprotection. The action of PRL on the nervous ...
