Exp Eye Res. 2007 May;84(5):978-90. Epub 2007 Feb 11. Similar declines occurred with either a high-K+ (20 mM) supplemented solution or the K+ channel inhibitor 4-aminopyridine. Activation of extracellular signal-regulated kinase (ERK), p38, and stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK) was time and tonicity-dependent. |

Epub 2007 Oct 13. Moreover, an activation of p38 MAPK was associated with the cytotoxicity of beta-Bgt. MK801 (an NMDA receptor antagonist), antibodies against NMDA receptor and 4-aminopyridine (a potassium channel blocker) markedly reduced the cytotoxic effects of beta-Bgt, B chain and catalytically inactivated beta-Bgt. |

| 20044444 | Gao L, Li Y, Schultz HD, Wang WZ, Wang W, Finch M, Smith LM, Zucker IH: Downregulated Kv4.3 expression in the RVLM as a potential mechanism for sympathoexcitation in rats with chronic heart failure. Am J Physiol Heart Circ Physiol. 2010 Mar;298(3):H945-55. Epub 2009 Dec 31. Employing this cell line, we also found that the ANG II-induced inhibition of Kv4.3 mRNA expression was attenuated by the scavenger Tempol and the p38 MAPK inhibitor SB-203580. In intact animals, we found that microinjection of the voltage-gated potassium channel blocker, 4-aminopyridine, into the RVLM evoked a sympathoexcitation and hypertension in both normal and CHF rats. |

Am J Physiol Gastrointest Liver Physiol. 2005 Nov;289(5):G815-21. Epub 2005 Jul 14. Blockade of K+ efflux with tetraethylammonium, 4-aminopyridine, stromatoxin, chromanol 293B, and the recently described K+ channel inhibitor 48F10 prevents DNA fragmentation, caspase activation, release of cytochrome c from mitochondria, and loss of mitochondrial membrane potential. Apoptotic K+ efflux critically depends on activation of p38 MAPK. |

J Neurosci. 2006 Nov 8;26(45):11652-64. Chronic exposure of human microglia to Abeta (1-42) led to enhanced p38 mitogen-activated protein kinase and nuclear factor kappaB expression with factors inhibited by 4-AP. |

Epub 2003 Feb 5. Significantly, the increased excitability evoked by IGF-I in the DCN cells depends both in vivo and in vitro, on activation of p38 mitogen-activated protein kinase (MAPK), a Ser-kinase known to modulate K+ channel activity. |

J Pharmacol Exp Ther. 2007 May;321(2):699-706. Epub 2007 Feb 22. The relaxant response to 8 was unaffected by the estrogen receptor antagonist ICI 182,780 (7alpha-[9-[(4,4,5,5,5-pentafluoropentyl]-sulfinyl] nonyl]-estra-1,3,5 (10)- triene-3,17beta-diol) and K+ channel blockers, i.e., TEA, glibenclamide, and 4-aminopyridine. Furthermore, the vasodilatory effect of 8 was unaffected by the adenylyl cyclase inhibitor SQ 22536 [9-(tetrahydro-2-furanyl)- the guanylyl cyclase inhibitor ODQ [1H-[1,2,4] oxadiazolo [4,3-a] quinoxalin-1-one], the protein kinase A inhibitor KT 5720 [(9S,10S,12R)-2,3,9,10,11,12-hexahydro-10--9-methyl-1-oxo-9,12-epox y-1H-diindolo [1,2,3-fg: 3',2',1'-kl] pyrrolo [3,4-i][1,6] benzodiazocine-10-carboxylic acid hexyl ester], the protein kinase G inhibitor KT 5823 [(9S,10R,12R)-2,3,9,10,11,12-hexahydro-10-methoxy-2,9-dimethyl-1-oxo-9,12- epoxy-1H-diindolo [1,2,3-fg:3',2',1'-kl] pyrrolo [3,4-i][1,6] benzodiazocine-1 0-carboxylic acid methyl ester], and the p38 mitogen-activated protein kinase (MAPK) inhibitor SB 203580 [4-(4-fluorophenyl)-2-(4-methylsulfinylphenyl)-5-(4-pyridyl)- . |

Exp Cell Res. 2004 Jul 15;297(2):461-71. UV-induced, but not H (2) O (2)-induced, JNK-1 phosphorylation was inhibited by pretreatment with 4-aminopyridine (4-AP), a K (+) channel blocker. 4-AP also blocked UV-induced increase in JNK activity as well as p38 phosphorylation. |
