MAPK3 — PRL
Text-mined interactions from Literome
Kanasaki et al., Biol Reprod 1999
(Pituitary Neoplasms...) :
We examined whether
mitogen activated protein ( MAP ) kinase is activated by thyrotropin releasing hormone (TRH) in GH3 cells, and whether MAP kinase activation is
involved in secretion of
prolactin from these cells
Wang et al., Mol Endocrinol 1999
(Pituitary Neoplasms) :
A role for the
mitogen activated protein kinase in mediating the ability of thyrotropin releasing hormone to
stimulate the
prolactin promoter ... Treatment with the MAPKK inhibitor, PD98059, blocked TRH induced activation of MAPK and also reduced TRH induction of a PRL-luciferase reporter gene, confirming that
MAPK activation is
necessary for TRH effects on
PRL gene expression
Barash et al., Mol Cell Endocrinol 1999
:
However, a line of evidence suggested that although this kinase phosphorylates PHAS-I in vitro, it does not actively participate in its phosphorylation in vivo : ( a ) the level of insulin needed to enable
PRL induced
ERK-1/ERK-2 activation was one order of magnitude higher than that needed for PHAS-I phosphorylation ; and ( b ) PD 098059, a MEK-1 inhibitor, completely inhibited insulin dependent, PRL induced ERK-1/ERK-2 activation but had no effect on the PRL induced PHAS-I phosphorylation
Goupille et al., Mol Cell Endocrinol 2000
:
Effect of
PRL on
MAPK activation : negative regulatory role of the C-terminal part of the PRL receptor ... The aim of the present study was to delineate the functional domains of the PRL receptor involved in
PRL induced
MAPK regulation ... Using various PRL-R mutants of the cytoplasmic domain we found, that the membrane proximal domain is necessary for
PRL induced
MAPK activation and that the C-terminal part of the receptor exerts a negative regulatory role ... A pharmacological approach, using different types of inhibitors, provided evidence that
PRL induced
MAPK activation requires both a MEK dependent pathway and a PI3K dependent pathway
Watters et al., Mol Endocrinol 2000
(MAP Kinase Signaling System) :
We report here that estrogeninduced
PRL expression
requires an intact mitogen activated protein kinase (
MAPK ) signal transduction pathway in cultured rat pituitary cells ( PR1 lactotroph and GH3 somatolactotroph cell lines )
Kievit et al., Mol Endocrinol 2001
(Pituitary Neoplasms) :
Analysis of the
role of the
mitogen activated protein kinase in mediating cyclic-adenosine 3',5'-monophosphate effects on
prolactin promoter activity ... Treatment of GH ( 3 ) cells with PD98059, an inhibitor of the MAPK pathway, reduced the ability of forskolin to activate a PRL reporter gene, providing evidence that
MAPK contributes to cAMP mediated effects on the
PRL promoter

MAPK inhibitor, PD98059,
blocked IGF-I evoked
PRL release as well as GH release inhibition over an 18-20-h incubation

MAPK phosphorylation and
PRL gene
activation

(Autoimmune Diseases...) :
p38
MAPK ( but not p42/p44 MAPK ) was
activated by
PRL in both leukocyte populations
Acosta et al., Mol Endocrinol 2003
:
We initially observed that
PRL dependent
activation of focal adhesion kinase ( Fak ),
Erk1/2 , and cell proliferation was mediated by c-Src in T47D cells, because expression of a dominant negative form of c-Src ( SrcDM, K295A/Y527F ) blocked the PRL dependent effects ... Expression of Fak mutant Y397F abrogated
PRL dependent activation of Fak,
Erk1/2 , and thymidine incorporation, but had no effect on p70S6K and Akt kinases ... MAPK kinase 1/2 ( Mek1/2 ) inhibitor PD184352 blocked
PRL induced stimulation of
Erk1/2 and cell proliferation ; however, p70S6K and Akt activation were unaffected ... The phosphatidylinositol 3-kinase (PI3K) inhibitor LY294002 abolished cell proliferation and activation of p70S6K and Akt ; however,
PRL dependent activation of
Erk1/2 was not modified
Amaral et al., Horm Metab Res 2003
:
PRL also induced JAK2, SHC, ERK1 and ERK2 phosphorylation in neonatal islets, demonstrating that
PRL can
activate MAPK
Domínguez-Cáceres et al., Oncogene 2004
:
Stimulation of W53 cell proliferation by
PRL required activation of
MAPK , as the Mek1/2 inhibitor PD184352 eliminated Erk1/2 stimulation, cell proliferation, and expression of c-Fos mRNA ... However, it reinforced
PRL activation of
Erk1/2
Lee et al., Cancer Res 2005
(MAP Kinase Signaling System) :
16-kDa
PRL effectively
inhibited IL-1beta-inducible p38
MAPK phosphorylation, resulting in blocking Stat1 serine phosphorylation, its subsequent nuclear translocation and activation of the Stat1 target gene IRF-1
Huang et al., Oncogene 2006
(Breast Neoplasms) :
Both PRL and EGF caused robust signaling in T47D cells ;
PRL acutely
activated JAK2, signal transducer and activator of transcription-5 ( STAT5 ), and
extracellular signal regulated kinase-1 and -2 ( ERK1 and ERK2 ), whereas EGF caused EGFR activation and consequent src homology collagen (SHC) activation and ERK activation

Inhibitors of Janus kinase ( JAK ), p38 MAPK, and
MAPK/ERK kinase (MEK) suppressed
prolactin- plus IFN-gamma induced CXCL9, CXCL10, and CXCL11 production and NF-kappaB, STAT1, and IRF-1 activities ...
Prolactin induced phosphorylation of JAK2 and ERK, whereas IFN-gamma induced phosphorylation of JAK1, JAK2, and p38

effect of
Prl on the well characterized
mitogen activated protein kinase ( MAPK ) and S6 kinase ( S6K ), the enzyme responsible for S6 phosphorylation in vivo, and their relationship to Nb2 macromolecular biosynthesis and mitogenesis were investigated
Johnson et al., J Biol Chem 1996
:
Prolactin inhibits epidermal growth factor induced
Ras-MAPK signaling in mammary epithelial cells ... To determine the
effects of
PRL on EGF induced
MAPK activation and phosphorylation, MAPK or phosphotyrosine ( Tyr ( P ) ) was immunoprecipitated from normal murine mammary epithelial ( NMuMG ) cells treated with PRL ( 100 ng/ml ) and/or EGF ( 10 ng/ml ) for 10-min periods ... The studies demonstrate that
PRL either directly or indirectly
inhibits the ability of EGF to induce EGF-R association with Grb2, to activate Ras, and to activate and phosphorylate
MAPK

From these data, it can be concluded that ( 1 ) the stimulation of CKII by prolactin in Nb2 cells is concomitant with cell multiplication : ( 2 )
MAPK stimulation is not
necessary for
prolactin to induce Nb2 cell multiplication ; and ( 3 ) PKC is stimulated in mammary and Nb2 cells, but this stimulation is not required for prolactin to stimulate casein, c-myc, beta-actin and stathmin gene expression and Nb2 cell division
