MEK5 activation of
ERK5
Chen et al., J Neurochem 2008
:
Although
mitogen activated protein kinase kinase ( MEK ) and extracellular signal regulated protein kinase ( ERK ) are activated by GW5074, pharmacological inhibition of
MEK-ERK signaling by U0126 or PD98059 does not
reduce neuroprotection suggesting that B-Raf signals through a non-canonical signaling pathway

These findings indicate that flow inhibits TNF mediated signaling events in EC by a mechanism

MEK5-BMK1 , but not

The involvement of epidermal growth factor receptor (EGFR)-extracellular signal regulated kinase ( ERK ) 1/2 cascade in CSC induced damage was shown by the observation that exposure to CSC ( 5 % ) induced a marked phosphorylation of ERK1/2, already detectable after 5-min incubation and confirmed by the demonstration that not only
ERK1/2 phosphorylation but also CSC induced TJ disassembly and DNA fragmentation were partially
inhibited by a
mitogen activated protein kinase kinase inhibitor ( U0126 ) and completely blocked by a EGFR inhibitor ( AG1478 )
