概括

使用无细胞DNA (cfDNA) 的非侵入性产前查现在可以检测出不仅仅是常见的胎儿瘤. 新兴的表观遗传和RNA生物标志物可以预测妊娠并发症,将产科护理转向预防.

科学领域:

基因组学就是基因组学.
表观遗传学在表观遗传学中,表观遗传学是指表观遗传学.
生物标志物发现发现

背景情况:

非侵入性产前查 (NIPS) 通常使用母体循环无细胞DNA (cfDNA) 来检测胎儿形状.
cfDNA包含母体和胎儿的遗传物质,以及表观遗传信息.

研究的目的:

探索遗传,表观遗传和片段性cfDNA特征超越化病,以了解孕产妇和胎儿的健康.
突出细胞自由RNA (cfRNA) 作为预测妊娠并发症的生物标志物.

主要方法:

对cfDNA遗传内容的分析.
评估cfDNA表观遗传特征和碎片组学.
对cfRNA进行生物标志物潜力的评估.

主要成果:

对cfDNA的遗传分析可以揭示超出常见形积分病的信息.
表观遗传和片段性cfDNA特征显示出作为健康和疾病生物标志物的前景.
cfDNA和cfRNA分析能够早期预测妊娠并发症,如产前激素和妊娠期糖尿病.

结论:

扩大NIPS的范围超出了动脉增生症,为母亲和胎儿健康提供了重要的见解.
cfDNA和cfRNA分析正在将产科护理转变为预防性,个性化医疗.
这种方法有望将产科护理从反应性转变为主动性管理.

Genetic Screens

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...
