LPA — RAC3
Text-mined interactions from Literome
He et al., Hypertension 2001
(Cardiovascular Diseases...) :
The nonreceptor tyrosine kinase Src and the small GTPase
Rac mediate the effects of both ET and
LPA in stimulation of the hBNP promoter ... These data suggest that ( 1 ) ET activates the hBNP promoter through a transcriptional mechanism ; ( 2 ) LPA, perhaps generated by iPLA ( 2 ), is involved in the effect of ET ; ( 3 ) Src and
Rac mediate ET and
LPA stimulation of the hBNP promoter ; and ( 4 ) ET regulation of the hBNP promoter targets both distal and proximal cis elements
Mayeenuddin et al., J Biol Chem 2006
:
LPA increased the amount of GTP bound Rac in the cells and isoproterenol reduced basal levels of GTP bound
Rac and blunted the effect of LPA
Sugimoto et al., Exp Cell Res 2006
:
Rho dependent, Rho kinase independent inhibitory
regulation of
Rac and cell migration by
LPA1 receptor in Gi-inactivated CHO cells ... Without PTX pretreatment,
LPA stimulates
Rac and cell migration yet similarly activates Rho, indicating that Rho activation by itself is not sufficient for inhibition of cell migration
Pilquil et al., J Biol Chem 2006
:
These included decreased
LPA induced activation of ERK and Rho, and the basal activities of
Rac and Cdc42
Lee et al., Mol Biol Cell 2008
(Colonic Neoplasms...) :
Consistent with negative modulation of the phosphatidylinositol 3 kinase pathway by LPA ( 4 ),
LPA ( 4 ) deficiency
potentiated Akt and
Rac but decreased Rho activation induced by LPA
Chen et al., Cancer Res 2010
(Neoplasm Metastasis...) :
Instead, we find that
LPA can
activate Rac only in metastatic cells and that metastatic colonization of ovarian cancer cells necessitates Rac activity ... These results thus suggest that
LPA induced
Rac activation is a prerequisite for ovarian cancer metastasis
Stam et al., EMBO J 1998
(Lymphoma, T-Cell...) :
Our results indicate that T-lymphoma invasion is driven by
Tiam1/Rac or Cdc42 activation, and is
dependent on
LPA/S1P receptor mediated RhoA and PLC signaling pathways which lead to pseudopod formation and enhanced infiltration
