prolactin

 [pro-lak´tin]
a hormone secreted by the anterior pituitary gland that promotes the growth of breast tissue and stimulates and sustains milk production in postpartum mammals, and shows luteotropic activity in certain mammals. Called also lactogenic hormone and mammotropin.

pro·lac·tin (PRL),

(prō-lak'tin), [MIM*176760]
A protein hormone of the anterior lobe of the hypophysis that stimulates the secretion of milk and possibly, during pregnancy, breast growth.
[pro- + L. lac, lact-, milk, + -in]

prolactin

(prō-lăk′tĭn)
n.
A pituitary hormone that stimulates and maintains the secretion of milk in mammals and also plays a role in metabolism and in modulation of the immune response.

prolactin

A gonadotropic hormone encoded by PRL on chromosome 6p22.2-p21.3 and secreted by the anterior pituitary, which in females stimulates mammary gland growth and lactation after childbirth.

pro·lac·tin

(PRL) (prō-lak'tin)
A protein hormone of the anterior lobe of the hypophysis that stimulates the secretion of milk and possibly, during pregnancy, breast growth.
Compare: bioregulator
Synonym(s): lactogenic hormone.

prolactin

One of the PITUITARY GLAND hormones. Prolactin stimulates the development and growth of the breasts (mammary glands) and helps to start and maintain milk production at the end of pregnancy.

Maternal and neonatal samples were kept in the refrigerator and analysed, on a daily basis, for prolactin by a fluorescence immunoassay that uses a sandwich immunodetection method [AFIAS prolactin kit (SMFP-8), Biotechnology, Boditech, Korea].
Sixty subjects who were enrolled in this RCT were patients of both gender, age ranging between 18-60 years (Mean +- SD 36.77 +- 9.686), who had psychosis as accompanying symptom/feature in any of the various psychiatric illnesses according to ICD-10 diagnostic criteria and had normal serum prolactin levels (below 20 ug/L in males and below 25 ug/L in females) at the start of study.
Dopamine receptor agonists, such as cabergoline or bromocriptine, have been shown to suppress prolactin secretion.
Mean prolactin level (464+- mIU/ml) was also significantly elevated (p = 0.039) in females with hormonal imbalance (Table 2).
The mean of age group, TSH, and prolactin level for subjects [Table 2] which shows that both the level of TSH and the level of prolactin are higher in the study subjects (males and females).
For prolactin and TLR4 gene expression analyses, average relative quantity of gene expression in the control group of the anterior pituitary explants collected from saline-treated ewes was set to 1.0.
Additionally, elevated prolactin directly inhibits basal and gonadotropin-stimulated ovarian secretion of estradiol and progesterone [2].
She was diagnosed to have a giant prolactinoma (40 x 45 x 30 mm, Figure 1(b)) with hyperprolactinaemia (serum prolactin 8930 ng/dL).
Serum prolactin was assayed from samples of children undergoing thyroid function evaluation who fulfilled the above criteria and who were diagnosed to have either ScH, overt primary hypothyroidism, or normal thyroid function.
