Nat Commun:英研究表明痛觉敏感性并非全由先天决定

2014-02-18 刘石磊 中国科学报

人的痛觉敏感性通常被认为主要是“天生”的,很难受后天影响而有所改变。但英国的一项新研究显示,生活方式和环境因素可通过“表观遗传”变化来改变基因表达,从而影响人们对疼痛的敏感性。 英国伦敦大学国王学院等机构的研究人员在新一期《自然—通讯》杂志上报告说,他们征集了25对同卵双胞胎进行痛觉敏感性测试,受试者手臂上装有自动升温的热探测器,他们在感觉探测器变烫时须按下按钮。 测试结果显示,虽然同卵双胞胎

人的痛觉敏感性通常被认为主要是“天生”的,很难受后天影响而有所改变。但英国的一项新研究显示,生活方式和环境因素可通过“表观遗传”变化来改变基因表达,从而影响人们对疼痛的敏感性。

英国伦敦大学国王学院等机构的研究人员在新一期《自然—通讯》杂志上报告说,他们征集了25对同卵双胞胎进行痛觉敏感性测试,受试者手臂上装有自动升温的热探测器,他们在感觉探测器变烫时须按下按钮。

测试结果显示,虽然同卵双胞胎拥有100%相同的基因,但他们对疼痛的敏感性并不一样。这说明,在某对双胞胎的基因序列未发生变化的情况下,其基因表达却因长期外部环境或生活方式等因素的影响发生了改变,这种现象就是“表观遗传”变化。研究人员进一步对这些同卵双胞胎进行了基因测序,发现有9种与痛感相关的基因存在“表观遗传”变化所特有的标记,其中就包括已知的痛感基因“TRPA1”,这种基因已被一些止痛药用作治疗靶点。
