Text-mined interactions from Literome
Alexander et al., Invest Ophthalmol Vis Sci 2001
:
Agents that modulate
protein kinase A (PKA) or
inhibit phosphatidylinositol 3-kinase (PI3K) had minimal effects on trabecular MMP or TIMP induction by TNFalpha, whereas several agents that modulate PKC activity were effective
Trümper et al., J Endocrinol 2002
(MAP Kinase Signaling System) :
These interactions included : ( i ) a central role of tyrosine phosphorylation for stimulation of PKA/CREB, MAPK and PI3-kinase/PKB, ( ii ) inhibition of
PKA/CREB by the MAPK pathway at the level of MAPK kinase-1 or downstream, ( iii )
activation of MAPK signaling by
PI3-kinase and PKA at the level of extracellular-signal regulated kinase 1/2 or upstream, and ( iv ) activation of PKB by MAPK and PKA signaling at the level of PKB or upstream
Luconi et al., J Cell Sci 2004
:
These results demonstrate that
PI 3-kinase negatively
regulates sperm motility by interfering with
AKAP3-PKA binding, providing the first evidence of a molecular mechanism by which PKA can be targeted to sperm tails by interaction with tyrosine phosphorylated form of AKAP3
Carini et al., Gastroenterology 2004
(Reperfusion Injury) :
In the cells treated with CGS21680,
PI3K activation was
prevented either by inhibiting adenylate cyclase and
PKA with, respectively, 2,5-dideoxyadenosine and H89 or by blocking Galphai-protein and Src tyrosine kinase with, respectively, pertussis toxin and PP2
Park et al., Biochem Biophys Res Commun 2009
:
HO-1 expression by PGE ( 2 ) was inhibited by LY294002,
PI3K inhibitor and H89,
PKA inhibitor
Agati et al., J Biol Chem 1998
:
Thus, insulin inhibition of
PKA induced PEPCK expression does not require MAPK activation but does
require activation of
PI3-kinase , although this signal is not transmitted through the PKB or PKC pathways
