Research Abstract

Chronic ingestion of ethanol upregulates the Ca^<2+> channel activity, which in turn increases the intracellular Ca^<2+>-concentration, resulting in neuronal cell damage. Intracellular elevation of Ca^<2+> via the activation of Ca^<2+> channel is also revealed in dementia such as Alzheimer's disease (AD), etc. In the present study, it was shown that ethanol exposure to cultured neuronal cells augments annexin A4 expression and accompanied by the activation of NF-κB. Annexin A4 directly bound to NF-κB and the Ca^<2+> binding sites on annexin A4 were involved in this event. We further investigated the quantitative alteration of the secreted proteins by Ca^<2+>-stress with neuronal culture cells. The amounts of secreted proteins were investigated after exposure to Ca^<2+>-ionophre (A23187) under the condition where cell viability was comparable with untreated control. Several proteins were shown to be increased by A23187. After two dimensional-gel electrophoresis, the proteins were identified by LC-MS spectrometry. The data base searching indicated that these three spots are annexin A2, fetuin, annexin A5 and SLUG. These proteins might be biological markers of dementia. We next focused on annexin A5 and analyzed it in blood plasma of dementia patients using sandwich ELISA. It was shown that plasma level of annexin A5 was significantly higher in dementia patients (AD, vascular and alcoholic dementia) than in healthy controls. However, it is hard to detect early stage of AD by this method. The physiological feature of these proteins in the etiology of AD is uncovered in the next step.
