Resumo
Consolidation of the conditioned food aversion response in Helix lucorum was associated with induction of histone H3 acetylation and methylation. We hypothesized that not only activatory, but also inhibitory p38 MARK-mediated pathways are involved in these processes. To assess the contribution of p38 MAPK to epigenetic processes, we studied the effect p38 MAPK inhibitor SB203580 on acetylation of histone H3 during training of Helix lucorum. Administration of SB203580 decreased learning-induced enhancement of histone H3 acetylation in the CNS of Helix lucorum, which was accompanied by long-term memory impairment. Thus, p38 MAPK is involved in the regulation of epigenetic mechanisms of long-term memory.
