AKT3 — RELA
Pathways - manually collected, often from reviews:
Text-mined interactions from Literome
Sizemore et al., Mol Cell Biol 1999
:
Additionally, the expression of a constitutively activated form of either p110 or the PI3K activated protein kinase
Akt also
induces p65/RelA mediated transactivation
Ozes et al., Nature 1999
:
Wortmannin ( a PI(3)K inhibitor ), dominant negative PI(3)K or kinase-dead
Akt inhibits TNF mediated
NF-kappaB activation ... Constitutively active
Akt induces
NF-kappaB activity and this effect is blocked by dominant negative NIK ... Conversely, NIK activates
NF-kappaB and this is
blocked by kinase-dead
Akt ... Thus, both
Akt and NIK are
necessary for TNF activation of
NF-kappaB ... Mutation of this amino acid blocks phosphorylation by
Akt or TNF and
activation of
NF-kappaB
Madrid et al., Mol Cell Biol 2000
:
Oncogenic Ras, an upstream activator of
Akt ,
requires NF-kappaB to initiate transformation, at least partially through the ability of NF-kappaB to suppress transformation associated apoptosis ... In this study, we show that oncogenic H-Ras
requires PI3K and
Akt to stimulate the transcriptional activity of
NF-kappaB ... Our work demonstrates that, unlike activated Ras, which can stimulate parallel pathways to activate both DNA binding and the transcriptional activity of NF-kappaB,
Akt stimulates
NF-kappaB predominantly by upregulating of the transactivation potential of p65
Burow et al., Biochem Biophys Res Commun 2000
:
PI3K and
Akt stimulated
NF-kappaB activation in a dose dependent manner, suggesting a common link between these two pathways ... We demonstrate that while both TNFR1 and NIK are partially involved in
Akt induced
NF-kappaB stimulation, a dominant negative IkappaBalpha completely blocked Akt-NF-kappaB cross-talk ...
PI3K-Akt signaling
activated NF-kappaB through both TNFR signaling dependent and -independent mechanisms, potentially representing a mechanism by which Akt functions to suppress apoptosis in cancer
Rauch et al., FEBS Lett 2000
:
PDGF induced
Akt phosphorylation does not
activate NF-kappa B in human vascular smooth muscle cells and fibroblasts ... The present study investigates the
role of
Akt in the activation of
NF-kappa B by tumor necrosis factor-alpha ( TNF alpha, 10 ng/ml ) and PDGF-BB ( 20 ng/ml ) in human vascular smooth muscle cells ( SMC ), skin and foreskin fibroblasts ... These data suggest that
Akt phosphorylation is not
involved in
NF-kappa B activation in human SMC and fibroblasts
Yang et al., J Biol Chem 2001
:
Whereas constitutively active PI-3K and
Akt induce
NF-kappaB activation, Ly294002 ( a PI-3K inhibitor ), dominant negative PI-3K, and kinase-dead Akt block IFN dependent NF-kappaB activation
Pianetti et al., Oncogene 2001
(Breast Neoplasms...) :
Overexpression of Her-2/neu and EGFR-4 in Ba/F3 cells led to constitutive PI3- and
Akt kinase activities, and
induction of classical
NF-kappaB ( p50/p65 )
Factor et al., Hepatology 2001
(Liver Neoplasms, Experimental) :
Roles of
Akt/PKB and IKK complex in constitutive induction of
NF-kappaB in hepatocellular carcinomas of transforming growth factor alpha/c-myc transgenic mice
Zhen et al., Mol Pharmacol 2001
:
Activation of NF-kappa B by 1 microM PD168077 was attenuated in D ( 4 ) MN9D cells that were transfected with a kinase-deficient Akt but not in cells transfected with a dominant negative Ras ( N17Ras ), suggesting that
NF-kappa B activation
requires Akt but is independent of Ras
Shao et al., Cancer Res 2001
(Ovarian Neoplasms) :
To test whether
Akt is regulated by E1A and is
involved in radiation induced
NF-kappaB activity, we examined the phosphorylation status of Akt in the E1A transfectants and parental cells and in irradiated cells ... We found that dominant negative
Akt and wortmannin did not
block radiation induced
NF-kappaB activity
Thomas et al., J Biol Chem 2002
:
Finally, both PI 3-K inhibition by LY294002 and
AKT inhibition by transfection of a dominant negative enzyme
blocked RSV induced
NF-kappaB transcriptional activity
Hatano et al., Am J Physiol Gastrointest Liver Physiol 2001
:
Active
Akt induces
NF-kappa B transcriptional activity but not NF-kappa B binding activity or I kappa B degradation
Yum et al., J Immunol 2001
(Endotoxemia...) :
In the present study, we found that exposure of neutrophils to endotoxin resulted in phosphorylation of
Akt ,
activation of
NF-kappaB , and expression of the proinflammatory cytokines IL-1beta and TNF-alpha through PI3-K dependent pathways
Vancurova et al., J Virol 2002
(Laryngeal Neoplasms...) :
Increased
NF-kappaB activity and cytoplasmic accumulation of p21 ( CIP1/WAF1 ) might counteract death promoting effects elicited by overexpressed PTEN and
reduced activation of
Akt and STAT3 previously noted in these tissues
Mayo et al., J Biol Chem 2002
:
Although the Akt pathway has been implicated in regulating NF-kappaB activity, it is controversial as to whether
Akt activates
NF-kappaB predominantly through mechanisms that regulate nuclear translocation or transactivation potential ... Maintenance of the PTEN tumor suppressor protein is therefore required to modulate
Akt activity and to concomitantly
control the transcriptional activity of the anti-apoptotic transcription factor
NF-kappaB
Chen et al., J Biol Chem 2002
:
In human embryonic kidney 293 cells, IL-1beta induces IkappaB kinase beta (IKKbeta) activation, IkappaBalpha degradation,
NF-kappaB transactivation , and weak
Akt activation ... Taken together, these results indicate a novel regulatory mechanism for IL-1beta signaling and suggest that CaMKK dependent
Akt activation
inhibits IL-1beta induced
NF-kappaB activation through interference with the coupling of IRAK1 to MyD88
Kane et al., Mol Cell Biol 2002
:
Akt appears to function upstream of Cot, as
Akt can
enhance Cot induction of
NF-kappa B-dependent transcription, and dominant negative Cot blocks the activation of this element by Akt
Mitsiades et al., Oncogene 2002
(Multiple Myeloma) :
In contrast, IL-6 does not cause sustained
NF-kappaB activation,
induces less pronounced
Akt activation and FKHRL-1 phosphorylation than IGF-1, and increases the expression of only survivin
Bozinovski et al., J Biol Chem 2002
(MAP Kinase Signaling System) :
Granulocyte/macrophage-colony stimulating factor ( GM-CSF ) regulates lung innate immunity to lipopolysaccharide through
Akt/Erk activation of
NFkappa B and AP-1 in vivo
Condorelli et al., FASEB J 2002
:
Here we demonstrate in neonatal rat cardiomyocytes that 1 ) TNF-alpha induces phosphorylation of AKT, activation of NF-kappaB, and the phosphorylation of JUN kinase ; 2 ) blocking
AKT activity
prevents NF-kappaB activation, suggesting a role for AKT in regulating NF-kappaB function ; 3 ) AKT and JUN are both critical for the hypertrophic effects of TNF-alpha, since dominant negative mutants of these genes are capable of inhibiting TNF-alpha induced ANF-promoter up-regulation and increase in cardiomyocyte cell size, and 4 ) blocking NF-kappaB, AKT, or JUN alone or in combination does not sensitize cardiomyocytes to the proapoptotic effects of TNF-alpha, in contrast to other cell types, suggesting a cardiac-specific pathway regulating the anti-apoptotic events induced by TNF-alpha
Figueroa et al., Exp Hematol 2002
(Anoxia) :
Genetic inhibition of
AKT resulted in significant inhibition of
NF-kappaB and HIF-1 mediated transactivation, as well as EPO gene expression, in response to hypoxia ... Overexpression of constitutively active
AKT resulted in increased
NF-kappaB and HIF-1 transactivation
Dhawan et al., Cancer Res 2002
(Disease Progression...) :
The purpose of this study was to explore the
role of
Akt in the activation of
NF-kappaB during melanoma tumor progression
Santos et al., J Biol Chem 2003
(Skin Neoplasms) :
Given the
roles of
Akt in
NF-kappa B signaling and the importance of these processes in the epidermis, a study was made into the possible alterations of the NF-kappa B pathway in transgenic mice expressing K10 in the proliferative basal layer ... It was found that the inhibition of
Akt , mediated by K10 expression,
leads to impaired
NF-kappa B activity
Lee et al., J Biol Chem 2003
:
LY294002, dominant negative ( DN ) phosphatidylinositol 3-kinase (PI3K), or
AKT ( DN )
inhibited NFkappaB activation, p65 transactivation, and cyclooxygenase-2 (COX-2) expression induced by lauric acid or constitutively active ( CA ) TLR4 ...
AKT ( DN )
blocked MyD88 induced
NFkappaB activation, suggesting that AKT is a MyD88 dependent downstream signaling component of TLR4 ...
AKT ( CA ) was
sufficient to induce
NFkappaB activation and COX-2 expression ... DHA also suppressed
NFkappaB activation
induced by TLR4 ( CA ), but not MyD88 ( CA ) or
AKT ( CA ), suggesting that the molecular targets of DHA are signaling components upstream of MyD88 and AKT
Kumar et al., Neoplasia (New York, N.Y.) 2003
(Prostatic Neoplasms) :
Overexpression of constitutively active
Akt , but not the kinase dead mutant of Akt,
activated the basal
NFkappaB transcriptional activity
Li et al., Infect Immun 2003
:
The dominant negative mutant of
Akt partially
inhibited the
NF-kappa B luciferase activity evoked by LPS and IL-1 beta ... Further, these studies suggest that PI3-kinase is an important mediator of LPS and IL-1 beta signaling leading to NF-kappa B activation in endothelial cells and that
Akt is
necessary but not sufficient for
NF-kappa B activation by TLR4
Cenni et al., Biochem J 2003
:
We also demonstrate that
Akt activity is
necessary for IL-1 dependent
NF-kappaB transactivation, since a kinase-defective mutant of Akt impairs IRAK2- and MyD88 dependent, but not IRAK1 dependent, NF-kappaB activity, as monitored by a gene reporter assay ... However, NF-kappaB binding to DNA was not affected by inhibition of Akt, indicating that
Akt regulates
NF-kappaB at a level distinct from the dissociation of p65 from IkappaBalpha and its translocation to the nucleus, possibly involving phosphorylation of the p65 transactivation domain
Gustin et al., J Biol Chem 2004
:
Phosphatidylinositol (PI)
3-kinase/Akt signaling
activates NF-kappa B through pleiotropic, cell type-specific mechanisms ... Thus, noncoordinate expression of I kappa B kinases plays a role in determining the cell type-specific
role of
Akt in
NF-kappa B activation
Chandrasekar et al., J Biol Chem 2004
(Arteriosclerosis...) :
However, treatment with pertussis toxin ( G ( i ) inhibitor ), wortmannin or LY294002 ( phosphatidylinositol 3-kinase ( PI3K inhibitors ) ), or Akt inhibitor or overexpression of dominant negative ( dn ) PI3K gamma, dnPDK-1, kinase-dead ( kd )
Akt , kdIKK-beta, dnIKK-gamma, dnI kappa B-alpha, or dnI kappa B-beta significantly
attenuated CXCL16 induced
NF-kappa B activation
Imose et al., Liver Int 2003
(Liver Failure) :
The inducible activation of
NF-kappaB and constitutive
activation of
Akt regulate hepatocyte survival against TNF-alpha, which occurs independent of Bcl-2 families
Afaq et al., Toxicol Appl Pharmacol 2004
(Edema...) :
In search for novel markers of skin tumor promotion, we found that TPA application to mouse skin resulted, as an early event, in an increased expression of phosphatidyinositol 3-kinase (PI3K), phosphorylation of
Akt at threonine308 and
activation of
nuclear factor kappa B (NF-kappaB)
Richmond et al., Novartis Found Symp 2004
(Cell Transformation, Neoplastic...) :
We have shown that the constitutive activation of NF-kappaB in human melanoma tumours is accompanied by constitutive activation of the
NF-kappaB inducing kinase (NIK) as well as the constitutive
activation of
AKT
Saleem et al., Oncogene 2004
(Edema...) :
We found that Lupeol treatment to mouse skin resulted in the inhibition of TPA induced ( i ) activation of PI3K, ( ii ) phosphorylation of
Akt at Thr ( 308 ), ( iii )
activation of
NF-kappaB and IKKalpha, and ( iv ) degradation and phosphorylation of IkappaBalpha
Wang et al., Lab Invest 2004
(Brain Neoplasms...) :
Functional correlation between
Akt activation and the
activation of
NFkappaB was confirmed in U251MG GBM cells in which inhibition of Akt activation either by stable expression of PTEN or by the PI3-kinase inhibitors, wortmannin and LY294002, led to a concomitant decrease in NFkappaB binding activity ... Thus, our results demonstrate that constitutive activation of Akt and NFkappaB, but not Stat3, contributes significantly to the progression of diffuse gliomas, and activation of
Akt may
lead to
NFkappaB activation in high-grade gliomas
Hsieh et al., Cell Signal 2004
(MAP Kinase Signaling System) :
In accordance with these findings, BK-induced phosphorylation of p42/p44 MAPK and
Akt and
activation of
NF-kappaB was attenuated by prior treatment with PD98059, LY294002, and helenalin, respectively
Kitagawa et al., Am J Physiol Gastrointest Liver Physiol 2004
:
Our results indicate that EGF and IL-1beta stimulate two essential signals for iNOS induction in IEC-6 cells : the upregulation of IL-1R1 through
PI3-kinase/Akt and the
activation of
NF-kappaB through IkappaB kinase, respectively
Palamakumbura et al., J Biol Chem 2004
:
Here we report, for the first time, that the lysyl oxidase propeptide, and not the lysyl oxidase enzyme, inhibits ras dependent transformation as determined by effects on cell proliferation assays, growth in soft agar, and
Akt dependent
induction of
NF-kappaB activity
Ahn et al., Cell Physiol Biochem 2005
:
Wortmannin inhibited NF-kappaB binding and transcriptional activity without inhibiting NF-kappaB translocation to the nucleus, indicating that
PI3K/Akt signaling
activates NF-kappaB transcriptional activity directly
Fan et al., Oncogene 2005
:
The ability of HGF/SF to activate
NF-kappaB signaling was
dependent on
c-Akt -- > Pak1 ( p21 associated kinase-1 ) signaling ( with Pak1 downstream of c-Akt ) and was inhibited by the tumor suppressor PTEN ( phosphatase and tensin homolog )
Petlickovski et al., Blood 2005
(Leukemia, Lymphocytic, Chronic, B-Cell...) :
This response was characterized by transient phosphorylation of extracellular signal related kinase ( ERK ) and
Akt ( protein kinase B [ PKB ] ), lack of activation of c-JUN NH2-terminal kinase (JNK) and p38 mitogen activated protein kinase ( MAPK ), and variable
activation of phospholipase Cgamma2 ( PLCgamma2 ) and
nuclear factor-kappaB (NF-kappaB)
Lee et al., Clin Cancer Res 2005

NF-kappaB activity in gastric cancer cells is controlled by and
controls Akt

(Cell Transformation, Viral) :
Activated
AKT regulates
NF-kappaB activation, p53 inhibition and cell survival in HTLV-1 transformed cells
Mehta et al., J Immunol 2005
(MAP Kinase Signaling System) :
Neither overexpression or inhibition of MEK, Ras, or
Akt affected HB-EGF mediated inhibition of
NF-kappaB activation
Wang et al., Cancer Res 2005
(MAP Kinase Signaling System) :
Because PTEN is a well-known phosphatase involved in the regulation of phosphatidylinositol 3-kinase (PI-3K)/Akt signaling pathway, taken together with the evidence that
PI-3K/Akt plays an important role in the activation of AP-1 and
NF-kappaB during tumor development, we anticipate that inhibition of AP-1 and NF-kappaB by tumor suppressor p53 seems to be mediated via PTEN, which may be a novel mechanism involved in anticancer activity of p53 protein

:
Inhibition of PI 3-kinase and
Akt attenuated RV39 induced
NF-kappaB transactivation and IL-8 expression

Davies et al., Mol Cell Biol 2005
:
In fibroblasts lacking TRAF2 or in carcinoma cells in which TRAF2 has been depleted by RNA interference, the CD40 mediated activation of
NF-kappaB and JNK is significantly reduced, and the activation of p38 and
Akt is severely
impaired
Sugimori et al., J Bone Miner Metab 2005
:
BMP-2 prevents apoptosis of the N1511 chondrocytic cell line through
PI3K/Akt mediated
NF-kappaB activation ... We investigated the involvement of phosphatidylinositol 3-kinase
(PI3K)/Akt mediated
NF-kappaB activation by BMP-2 stimulation in the modulation of this antiapoptotic process in a chondrocytic cell line, N1511 ... Thus, BMP-2 induced
NF-kappaB activation is
mediated by
PI3K/Akt signaling
Choi et al., Mol Cells 2005
(MAP Kinase Signaling System) :
Even though the crucial involvement of the PI3-kinase/Akt pathway in the anti-apoptotic activation of NF-kB is well known, the exact
role of PDK-1 as well as

NF-kB activation is not understood
Kobashi et al., Circ Res 2005

NFkappaB and CXCL10 expression
Narayan et al., Mol Cell Biol 2006
:
We previously demonstrated a
role for the serine/threonine kinase
Akt in CD28 mediated
NF-kappaB induction ... Using a CARMA1-deficient T-cell line, we have now found that the CARMA complex is required for
induction of
NF-kappaB by
Akt , in cooperation with protein kinase C activation ... Furthermore, using a novel selective inhibitor of Akt, we confirm that
Akt plays a modulatory role in
NF-kappaB induction by the TCR and CD28
Hsieh et al., J Cell Physiol 2006
:
Moreover, S1P stimulated activation of NF-kappaB promoter activity was blocked by phosphatidylinositol 3-kinase (PI3K) inhibitor LY294002 and helenalin, but not by U0126, suggesting that
involvement of
PI3K/Akt in the activation of
NF-kappaB

reduced the LA-induced activation of
nuclear factor kappa B (NF-kappaB)
Gustin et al., J Biol Chem 2006
:
Constitutively active
Akt augments non-canonical
NF-kappaB activity, whereas kinase dead Akt or inhibition of phosphatidylinositol 3-kinase have the opposite effect ... These observations show that
Akt plays a role in activation of basal and induced non-canonical
NF-kappaB activity

:
Therefore, 5-FU was suggested to inhibit the LPS induced NO production in activated macrophages through preventing
Akt dependent

Quercetin also inhibited TNF-alpha induced PI 3-kinase activity,
Akt phosphorylation, intracellular H ( 2 ) O ( 2 ) production,
NF-kappaB transactivation , IL-8 promoter activity, and steady-state mRNA levels, consistent with the notion that quercetin inhibits chemokine expression by attenuating NF-kappaB transactivation via a PI 3-kinase/Akt dependent pathway

Liu et al., Mol Immunol 2007
:
Further studies show that the triptolide mediated inhibitory effects of LPS induced activation of phosphatidylinositol-3 kinase

NF-kappaB activation are involved in down-regulation of COX-2 and CCR7 expression resulting in impaired migration to secondary lymphoid organs of DC
Wang et al., Biochem Biophys Res Commun 2007
(Lung Neoplasms) :
The results show that
Akt contributes to TNF induced
NF-kappaB activation in lung cancer cells through regulating phosphorylation of the p65/RelA subunit of NF-kappaB ... Although individually blocking IKK or

Fan et al., J Biol Chem 2009
(MAP Kinase Signaling System...) :
The ability of Src to enhance SF stimulation of NF-kappaB activity was due, in part, to its ability to stimulate
