中文摘要
实验前24 h用5 -HT_1A受体激动剂预处理情绪应激小鼠,发现情绪应激小鼠海马乙酰化组蛋白H3增加,组蛋白去乙酰化酶抑制剂阿司他丁A对急性束缚应激引起的情绪变化也有保护作用,组蛋白H3乙酰化也有保护作用。本研究结果表明,基因调控的表观遗传机制可能在应激刺激的情绪抵抗力的发展中发挥重要作用。
英文摘要
We found that acetylated histone H3 was increased in the hippocampus of mice that had developed resistance to emotional stress by pretreatment with 5 -HT_1Areceptor agonist 24 h before testing.Interestingly, the histone deacetylase inhibitor trichostatin A also protected against the emotional changes induced by acute restraint stress, as well as histone H3 acetylation. The present findings suggest that the epigenetic mechanisms of gene regulation may play an important role in the development of emotional resistance to stress stimuli.
