Prolactin Activates Tyrosyl Phosphorylation of Insulin
Prolactin (PRL) has been demonstrated to induce tyrosine phosphorylation and activation of the cytoplasmic tyrosine kinase JAK2. The present study represents an initial effort to identify the phosphorylation repertoire of the PRL receptor (PRLR). For this purpose we have modified the rat PRLR cDNA to encode an additional N-terminal epitope specifically designed to allow the rapid purification o...
متن کاملOvarian hormones and prolactin increase renal NaCl cotransporter phosphorylation.
Unique situations in female physiology require volume retention. Accordingly, a dimorphic regulation of the thiazide-sensitive Na(+)-Cl(-) cotransporter (NCC) has been reported, with a higher activity in females than in males. However, little is known about the hormones and mechanisms involved. Here, we present evidence that estrogens, progesterone, and prolactin stimulate NCC expression and ph...
متن کاملAssociation of Prolactin and Prolactin Receptor Gene Polymorphisms with Economic Traits in Breeder Hens of Indigenous Chickens of Mazandaran Province
Polymorphisms in 5’-flanking region of prolactin (PRL), exon 2 and exon 5 of prolactin receptor (PRLR) genesand its association with growth and egg traits were examined in breeder hens of Mazandaran native fowlsbreeding station. A single nucleotide polymorphism at site C-2402T and a 24 bp nucleotide sequence insertionat situation -382 in 5’-flanking regions of PRL gene were id...
متن کاملProlactin induces ERK phosphorylation in epithelial and CD56(+) natural killer cells of the human endometrium.
Functional PRL receptors are expressed in the human endometrium during the secretory phase of the menstrual cycle in which PRL stimulates tyrosine phosphorylation of Janus kinase 2 and STAT (signal transducer and activator of transcription) 1 and 5. In this study, we investigated the effect of PRL on the MAPK/ERK pathway in the human endometrium. Human endometrial tissue was collected during th...
متن کاملStimulation of prolactin receptor induces STAT-5 phosphorylation and cellular invasion in glioblastoma multiforme
Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumor in humans and is characterized with poor outcome. In this study, we investigated components of prolactin (Prl) system in cell models of GBM and in histological tissue sections obtained from GBM patients. Expression of Prolactin receptor (PrlR) was detected at high levels in U251-MG, at low levels in U87-MG and b...
