Prolactin (also known as lactotropin and PRL) is a hormone that’s responsible for lactation, certain breast tissue development and contributes to hundreds of other bodily processes. Prolactin levels are normally low in people assigned male at birth (AMAB) and non-lactating and non-pregnant people.
Prolactin (PRL), also known as lactotropin and mammotropin, is a protein best known for its role in enabling mammals to produce milk. It is influential in over 300 separate processes in various vertebrates, including humans. [5] Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation and ...
Prolactin (PRL) is a protein hormone with a molecular weight of approximately 23 KD, although variants in size exist. It binds to receptor dimers on the cytoplasmic surface of its target cells and acts primarily through the activation of the STAT5 pathway, which in turn alters gene activity.
21 mar 2019 · The principal role of prolactin in mammals is the regulation of lactation. Prolactin is a hormone that is mainly synthesized and secreted by lactotroph cells in the anterior pituitary...
24 lip 2023 · Prolactin is a polypeptide hormone responsible for lactation, breast development, and hundreds of other actions needed to maintain homeostasis. The chemical structure of prolactin is similar to the structure of growth and placental lactogen hormones.
6 lut 2024 · Prolactin (PRL) is a pleiotropic hormone released from lactotrophic cells of the anterior pituitary gland that also originates from extrapituitary sources and plays an important role in regulating lactation in mammals, as well as other actions.
The main function of prolactin is during pregnancy and lactation in the development of mammary glands, milk synthesis and maintenance of milk secretion. Serum prolactin levels rise rapidly during pregnancy with increase in the size and number of lactotrophs.
