Teixeira et al., J Neurochem 2000
:
Our results suggest that ET-1 induced expression of cyclins D1 and D3 is dependent on the ERK- and CSK dependent pathways, respectively ; moreover, a decrease in the levels of the cyclin dependent kinase inhibitor (CKI)
p27 was observed as a
consequence of
ERK activation
Das et al., FEBS Lett 2000
:
This implies that a link exists between
ERK activation and p21 ( WAF ) and
p27 ( kip1 )
induction in the process of terminal differentiation
He et al., Immunol Lett 2005
:
Inhibiting
ERK activation
reduced the increased expression of
p27 and Bax, but had no effect on the decreased expression of Bcl-2, suggesting the involvement of ERK activation in the SN-induced increased expression of p27 and Bax
Sakakibara et al., J Biol Chem 2005
(MAP Kinase Signaling System) :
Conversely, direct activation of ERK via adenovirus mediated expression of a constitutively active form of MEK led to a reduction of p27 protein and mRNA, further supporting the central
role of
ERK in regulation of
p27 expression
Hu et al., Mol Biol Cell 2005
:
Furthermore, in response to H2O2, inhibition of
ERK activation
repressed p66shcA dependent phosphorylation of FOXO3a and the down-regulation of its target gene
p27kip1
Bagui et al., Cell cycle (Georgetown, Tex.) 2009
:
Inhibition of
p27 ( Kip1 ) gene expression by PDGF
required protein synthesis and histone deacetylase activity but not Akt or
ERK activity
Pearson et al., Breast Cancer Res 2009
(Disease Progression...) :
Both
ERK1/2 and PI-3 kinase dependent effector pathways were
required for activated Raf : ER to reduce expression of
p27 and promote proliferation
Okumura et al., J Gastroenterol 2010
(Gastrointestinal Neoplasms...) :
p27 ( Kip1 ) accumulation
results from the inhibition of the ubiquitin-proteasome system and/or inhibition of
MEK-ERK signaling
Gopinath et al., Mol Oncol 2011
(Glioma) :
In the present study, shRNA against cathepsin B and uPAR as well as specific inhibitors, Wortmannin ( 10 µM ) and U0126 ( 10 µM ), were used to determine the
roles of AKT and
ERK signaling on
p27 expression ... Immunoblot analysis demonstrated that downregulation of both
p-ERK and p-AKT downstream of EGFR and ß1 integrin are
involved in the
p27 upregulation
Huang et al., PloS one 2012
(Endometrial Neoplasms) :
The present studies demonstrate that E2 stimulates growth of ECA cell lines and normal primary endometrial epithelial cells ( EECs ) and induces
MAPK-ERK1/2 dependent phosphorylation of
p27 on Thr187, a prerequisite for p27 ubiquitylation by nuclear SCF-Skp2/Cks1 and subsequent degradation
McKinley et al., J Nucl Med 2013
(Colorectal Neoplasms...) :
Reduced F-FLT PET reflected a modest, yet significant, reduction of Ki67 immunoreactivity,
inhibition of p-MEK and
p-ERK , and elevated tumor cell
p27 protein levels
