EPHB2 — LIF
Text-mined interactions from Literome
Nagamoto-Combs et al., J Neurochem 1999
(Second Messenger Systems) :
These results indicate that
LIF mRNA levels can be
regulated by
ERK activation via stimulation of PKC in Schwann cells
Kodama et al., Am J Physiol Heart Circ Physiol 2000
(Cardiomegaly) :
LIF sequentially
activated Raf-1, MEK1/2,
ERK1/2 , and p90 ( RSK )
Schuringa et al., Exp Cell Res 2002
(Teratocarcinoma) :
In contrast,
LIF does not
activate STAT3,
ERK , or the gp130 receptor in human N tera-2/D1 EC cells, although all receptor components are expressed
Nakao et al., Br J Pharmacol 2002
:
3 : Both PD98059 (
MAPK/ERK kinase inhibitor ) and SB203580 ( p38 MAPK inhibitor )
attenuated FCS induced
LIF protein production and gene expression ... 5 : These findings demonstrate that both
ERK and p38 MAPK are
involved in FCS induced
LIF secretion, whereas only p38 MAPK is important for IL-6 secretion, and that FCS induced activation of JNK has no effect on the production of LIF and IL-6
Chan et al., Blood 2003
:
LIF stimulated phospho-Stat3 ( known to be critical for ES cell self-renewal and maintenance of an undifferentiated state ) and
phospho-Erk levels were examined by immunoblotting
Kritikou et al., Development 2003
:
Inhibition of
LIF mediated
ERK1/2 phosphorylation potentiates the proapoptotic effects of STAT3
Yanagisawa et al., Genes Cells 2004
:
Disruption of lipid rafts by MBCD inhibited
LIF induced
ERK activation but not STAT3 activation
Yanagisawa et al., J Biochem 2005
(MAP Kinase Signaling System) :
Leukemia inhibitory factor (LIF) induced
ERK activation was also abolished in PDMP treated NECs, suggesting that PDMP specifically represses the Ras-MAPK pathway
Dekanty et al., J Biol Chem 2006
:
However,
LIF and PGF2alpha can
trigger increases in
ERK1/2 activity, which are required for their mitogenic responses because U0126, a MEK1/2 inhibitor, prevents both ERK1/2 activation and induction of DNA synthesis by LIF or PGF2alpha treatment
Mohri et al., J Biol Chem 2006
:
Here we describe that
leukemia inhibitory factor (LIF) , a member of IL-6 related cytokines,
activated STAT3 and
ERK1/2 in cardiac Sca-1+ stem cells
Levy et al., J Cell Biochem 2010
:
Tumor necrosis factor alpha
induces LIF expression through
ERK1/2 activation in mammary epithelial cells ... Our results show that TNFalpha was able to
induce LIF transcription through
ERK1/2 activation in a non-tumorigenic mouse mammary epithelial cell line, SCp2
Arthan et al., Cancer Lett 2010
(Carcinoma, Medullary...) :
Ras/Raf/MEK/ERK activation was
sufficient to induce growth inhibition and
LIF expression in the human MTC line MZ-CRC-1
Prakash et al., Reprod Fertil Dev 2011
:
Stimulation with
LIF resulted in the activation of both signal transducer and activator of transcription ( STAT ) 3 Tyr ( 705 ) and
ERK1/2 , but inhibition of ERK1/2 signalling by pretreatment of cells with U0126 ( 10 µM ) for 2h resulted in abrogation of LIF mediated increases in G ( 2 ) /M transition, with a significant decrease ( P < 0.05 ) in absolute cell numbers compared with control
Li et al., Protein Cell 2012
:
We recently found that while
LIF signaling
augments ERK activity, BMP signaling inhibits ERK activity in mouse ES cells via direct upregulation of an ERK phosphatase-dual-specificity phosphatase 9
