支气管肺发育不良的表观遗传学机制研究进展

Epigenetic mechanisms of bronchopulmonary dysplasia:a review

支气管肺发育不良是早产儿常见的慢性呼吸系统并发症,其发病机制尚未完全阐明,且暂无有效防治措施,严重影响早产儿存活率及预后。已有研究证实,组蛋白修饰、非编码RNA和DNA甲基化等表观遗传学机制在支气管肺发育不良的发生、发展过程中发挥重要作用,且相关表观遗传变化多为可逆性改变,可能为临床治疗提供重要靶点。因此,表观遗传学研究将为进一步认识支气管肺发育不良的发病机制及防治支气管肺发育不良提供新方向和思路。

Bronchopulmonary dysplasia(BPD)is a common chronic respiratory complication in preterm infants without fully understand the mechanism or effective treatment,which could significantly affect the survival rate and prognosis of these infants.Studies have confirmed that epigenetic mechanisms,including histone modification,non-coding RNA and DNA methylation may play an essential role in the onset and development of BPD.And most related epigenetic changes are reversible,which might serve as a potential target for BPD treatment.Therefore,further studies on epigenetics will shed light on a better understanding of the pathogenesis,prevention,and treatment of BPD.
