1 C-jun N-terminal kinase regulates the interaction between 14-3-3 and Bad in ethanol-induced cell death. Ethanol mitogen-activated protein kinase 8 Rattus norvegicus
2 Activation of the c-jun N-terminal kinase (JNK) is known to be an important step during ethanol-induced cell death, but it has yet to be identified how JNK regulates apoptosis. Ethanol mitogen-activated protein kinase 8 Rattus norvegicus
3 Activation of the c-jun N-terminal kinase (JNK) is known to be an important step during ethanol-induced cell death, but it has yet to be identified how JNK regulates apoptosis. Ethanol mitogen-activated protein kinase 8 Rattus norvegicus
4 Therefore, we investigated the mechanism by which JNK induces cell death following ethanol treatment. Ethanol mitogen-activated protein kinase 8 Rattus norvegicus
5 Ethanol exposure induced phosphorylation of JNK but did not affect the expression levels of pro- and antiapoptotic proteins. Ethanol mitogen-activated protein kinase 8 Rattus norvegicus
6 Furthermore, interactions of phospho-JNK (p-JNK) with 14-3-3 as well as with Bad were enhanced in the cerebral cortices of ethanol-treated rats. Ethanol mitogen-activated protein kinase 8 Rattus norvegicus
7 Furthermore, interactions of phospho-JNK (p-JNK) with 14-3-3 as well as with Bad were enhanced in the cerebral cortices of ethanol-treated rats. Ethanol mitogen-activated protein kinase 8 Rattus norvegicus
8 Pretreatment with JNK inhibitor (SP600125) of SH-SY5Y cells inhibited JNK phosphorylation and interaction between p-JNK and 14-3-3 resulting from ethanol. Ethanol mitogen-activated protein kinase 8 Rattus norvegicus
9 We hypothesize that JNK may play an important role during ethanol-induced cell death via the inhibition of antiapoptotic function of 14-3-3 as well as activation of proapoptotic function of Bad. Ethanol mitogen-activated protein kinase 8 Rattus norvegicus
