概括

对无细胞DNA (cfDNA) 的片段学分析可以使用向的外因子面板,而不仅仅是全基因组测序 (WGS). 这种方法可以实现癌症表型,使cfDNA分析更容易获得临床应用.

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.
分子生物学分子生物学

背景情况:

无细胞DNA (cfDNA) 的碎片学为表观遗传和转录数据提供了洞察力.
目前的方法通常依赖于全基因组测序 (WGS),其临床可用性有限.
向的外面板是临床cfDNA变异检测的标准.

研究的目的:

调查基于WGS的已建立的碎片组学方法在向癌症外面板上的适用性.
用临床测序面板评估不同片段学策略的性能.
为了确定cfDNA碎片组学是否可以通过向测序适应临床环境.

主要方法:

应用多个已发表的WGS碎片组学方法,以癌症向的外面板数据.
评估策略使用规范深度指标和面板上所有可用的外形.
对癌症表型定型的各种瘤部分的性能进行比较.

主要成果:

规范化的深度度度指标和利用所有面板外因子通常改善了癌症表型预测.
特定的fragmentomics指标在特定应用中显示出高性能.
商业临床向测序小组显示了可比的癌症表型表现性能,最小的减少.

结论:

使用有针对性的测序面板,cfDNA的碎片分析是可行的.
全基因组测序 (WGS) 对于cfDNA碎片组学来说并不严格必要.
这种适应增强了cfDNA碎片组学在癌症检测和表型化方面的临床实用性.

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...
