Nat Commun:鼻甲基化组可以作为儿童哮喘和气道炎症的生物标记

2019-08-04 AlexYang MedSci原创

鼻细胞表观基因组学可能能够作为气道疾病和环境响应的生物标记。最近,有研究人员从547名儿童(平均年龄12.9岁)中搜集了前鼻孔的鼻拭子并测量了DNA甲基化情况。研究人员对哮喘、过敏原敏感、过敏性鼻炎、呼出气一氧化碳(FeNO)和肺功能进行了鼻表观基因组关联分析(EWAS)。研究人员发现了哮喘(285-CPGS)、FeNO(8,372-CPGS;191-DMRs)、总IgE(3-CPGS;3-DMR

鼻细胞表观基因组学可能能够作为气道疾病和环境响应的生物标记。最近,有研究人员从547名儿童(平均年龄12.9岁)中搜集了前鼻孔的鼻拭子并测量了DNA甲基化情况。

研究人员对哮喘、过敏原敏感、过敏性鼻炎、呼出气一氧化碳(FeNO)和肺功能进行了鼻表观基因组关联分析(EWAS)。研究人员发现了哮喘(285-CPGS)、FeNO(8,372-CPGS;191-DMRs)、总IgE(3-CPGS;3-DMRs)、环境IgE(17-CPGS;4-DMRs)、过敏性哮喘(1,235-CPGS;7-DMRs)和支气管扩张剂反应(130-CPGS)多个不同的甲基化CpGs(FDR<0.05)和区域(DMRs;≥5-CpGs和FDR<0.05)。所发现的DMRs中注释的基因与过敏性哮喘、Th2激活和嗜酸粒细胞增多(EPX, IL4, IL13)相关基因有关,也包括了之前报道血液EWAS中的与哮喘和lgE相关的基因。另外,哮喘、lgE和FeNO与鼻表观年龄加速有关。

最后,研究人员指出,鼻表观基因组是哮喘、过敏和气道炎症的敏感生物标记。
