reach
"The effect of cochlin was opposite to the well-known effects of shear stress stimulation by fluid flow or arachidonic acid (20microM), which significantly increased TREK-1 current by 72.1 +/-21.9% and 148.7 +/-50.1%, respectively (n = 5 each; Fig."
reach
"Our data suggest that the opening of background K (+) channels, like TREK-1 and TRAAK, which are activated by arachidonic acid and other polyunsaturated fatty acids such as docosahexaenoic acid and linolenic acid, is a significant factor in this neuroprotective effect."
reach
"Furthermore, as predicted based on arachidonic acid activation of both TREK-1 and TREK-2, some of the small molecules from this TREK-2 HTS were found to activate both TREK-1 and TREK-2."

sparser
"Arachidonic acid (AA) which is generated during CRH stimulation activates TREK-1 channels and causes hyperpolarization."
reach
"It is unlikely that block of phospholipase A 2 underlies the substantive effects on TREK and TRESK channels seen here, because arachidonic acid enhances TREK (and TRAAK) channels (Fink et al., 1996; Enyedi and Czirjak, 2010) and blocks TRESK channels (Sano et al., 2003; Kang et al., 2004)."

reach
"These data, combined with previous studies of PLD2 activation of TREK-1, led us to propose a model where PIP 2 can directly antagonize TREK-1."
reach
"Channels like TREK-1 that are agonized by PA and directly inhibited by PIP 2 [XREF_BIBR] are likely the most affected since PEtOH and PIP 2 would combine to antagonize PA, and PA is in relatively low concentrations in the cell."
reach
"So why does PIP 2 antagonize TREK-1 in liposomes when PA and PG are activating?"
sparser
"The opposite effect of low and high levels of PIP 2 in the presence of PG ( xref and xref ) may suggest multiple sites for PIP 2 binding to TREK-1."

reach
"In contrast with PG and PA, increasing concentrations of PIP 2 (0.5, 1, and 2 mol%) failed to activate TREK-1 : the highest concentration of PIP 2, 2 mol%, induced the least flux (XREF_FIG and XREF_FIG)."
