慢性疼痛是一种疾病,其病因复杂、发生发展机制尚未明确,临床上尚缺乏有效的治疗手段。表观遗传调控与慢性疼痛的发生存在相关性。深入研究表观遗传调控组分与慢性疼痛的关系,寻找参与疼痛发生发展和药物治疗效果密切相关的表观遗传特定酶类与生物标志物,将有助于相关治疗新靶点的获得和新型镇痛药物的研发。综述表观遗传修饰即DNA甲基化与去甲基化、组蛋白乙酰化与去乙酰化、组蛋白甲基化及非编码RNA等,参与疼痛调控过程的研究进展,以期为临床疼痛药物研发提供可能的靶标分子。 Chronic pain is a disease, its etiology is complex, the mechanism of occurrence and development is not yet clear, and clinically there is a lack of effective treatment. Epigenetic regulation is associated with the occurrence of chronic pain. In-depth study of the relationship between epigenetic regulatory components and chronic pain, to find the epigenetic specific enzymes and biomarkers involved in the development of pain and drug treatment are related to the acquisition of new targets and new Analgesic drug research and development. This review summarizes the progress of epigenetic modification such as DNA methylation and demethylation, histone acetylation and deacetylation, histone methylation and non-coding RNA, which are involved in the process of pain regulation. Provide possible target molecules.
