PRKAR1A — TNF
Text-mined interactions from Literome
Nakamura et al., J Am Soc Nephrol 2001
:
However, inhibition of MAPK ( p42/p44 ) and
TNF-alpha promoter activity was partially
prevented by the
cAMP-protein kinase (PKA) inhibitors, H-89 ( 5 x 10 ( -6 ) M ) and KT5720 ( 10 ( -5 ) M ), whereas the suppression of p38 MAPK or NF-kappa B ( p50 ) was not blocked by these inhibitors ... It is likely that
cAMP-PKA and MAPK ( p42/p44, p38 ) may
play a critical role in the regulation of the Stx-2 induced
TNF-alpha transcription via beta(2)-adrenoceptor activation
Yoon et al., J Biol Chem 2003
:
Taken together, our results indicate that stimulation of
PKA by alpha-MSH causes inhibition of LPS induced activation of p38 kinase and NF kappa B to
block TNF-alpha production
Chen et al., Endocrinology 1992
:
TNF alpha increased cAMP and also increased relative
PKA and PKC activity in 1-40 min. Phorbol myristate acetate ( PMA ), an activator of PKC, increased [ 3H ] thymidine incorporation and DNA content
Aronoff et al., J Immunol 2005
:
By contrast, activation of
PKA , but not Epac-1,
suppressed AM production of leukotriene B ( 4 ) and
TNF-alpha , whereas stimulation of either PKA or Epac-1 inhibited AM bactericidal activity and H ( 2 ) O ( 2 ) production
Zhao et al., Cell Immunol 2005
(MAP Kinase Signaling System) :
Although gAd partially increased cAMP concentration and
PKA activity, it directly reduced leptin induced ERK1/2 and p38 MAPK phosphorylation thus
inhibiting TNF-alpha production
Hichami et al., Mediators Inflamm 1996
:
We investigated the
effects of specific inhibitors of cAMP dependent
protein kinase (PKA) and cGMP dependent protein kinase ( PKG ) on the inhibitory activity of phosphodiesterase ( PDE ) type 4 inhibitors and of the cell permeable analogue of cAMP, db-cAMP on LPS induced
TNF-alpha release from human mononuclear cells
Beck et al., Biochem Pharmacol 2009
(Inflammation) :
Although H89 can inhibit both MSK1 and PKA,
TNF does not
activate PKA ( EC 2.7.11.11 ) and as such PKA inhibition does not mediate H89 instigated repression of TNF stimulated gene expression
Wall et al., Science signaling 2009
(Inflammation...) :
Suppression of LPS induced
TNF-alpha production in macrophages by cAMP is
mediated by
PKA-AKAP95-p105
Kim et al., J Biol Chem 2011
:
AKAP10 also mediated PGE ( 2 ) potentiation of the expression of cytokines IL-10 and IL-6, whereas PGE ( 2 ) suppression of
TNF-a was
mediated by AKAP8 anchored
PKA-RII
Ji et al., Hepatology 2013
(Liver Diseases...) :
In vitro, PACAP treatment not only diminished macrophage
tumor necrosis factor alpha/IL-6/IL-12 levels in a
PKA dependent manner, but also prevented necrosis and apoptosis in primary mouse hepatocyte cultures
Scheurich et al., J Exp Med 1989
:
As activation of PKA does not slow down the degradation rate of TNF-Rs, but rather enhances protein synthesis dependent reexpression of TNF-Rs after transient PKC mediated transmodulation and after tryptic digestion of TNF-Rs, it is concluded that
PKA stimulates
TNF-R synthesis ...
PKA mediated enhancement of
TNF-R expression was predominantly observed in normal peripheral blood monocytes and tumor cell lines of myeloid origin ... As in these typical TNF producer cells, the production of
TNF is also
controlled by
PKA and PKC, a regulatory circuit is proposed, by which these two independent signal pathways antagonistically regulate TNF production and, at the receptor level, TNF sensitivity
Seldon et al., Mol Pharmacol 1995
:
When PGE2 was used to activate adenylyl cyclase, however, rolipram potentiated cAMP accumulation,
PKA activation, and
inhibition of
TNF-alpha generation
