概括

研究人员使用RNA-seq数据在从未吸烟者中确定了三种肺腺癌亚型 (NS-LUAD). 一个侵略性的亚型,一个侵略性的亚型.

科学领域:

在瘤学瘤学.
基因组学就是基因组学.
文字转录学 (Transcriptomics) 是一个学科.

背景情况:

了解瘤细胞动态对于肺腺癌的预后和治疗至关重要,特别是在从未吸烟者 (NS-LUAD) 中.
目前对NS-LUAD瘤细胞动态和亚型的了解有限.
转录组数据为对侵略性瘤亚型的分类提供了潜在的途径.

研究的目的:

在从不吸烟的肺腺癌 (NS-LUAD) 中识别和表征不同的瘤细胞亚型.
调查这些亚型的预后影响.
为改进NS-LUAD预后开发一个转录基因签名.

主要方法:

分析了684名NS-LUAD患者的RNA测序数据.
综合基因组和组织学数据用于亚型表征.
开发并验证了60个基因签名用于分类和生存预测.

主要成果:

确定了三种NS-LUAD亚型:"稳定" (预后有利),"繁殖" (中间) 和"混乱" (预后最差).
"混沌"亚型表现出高的上皮细胞到介质酶细胞过渡标记,并且只能通过转录组学识别.
60基因签名准确地回顾了亚型分类,并预测了不同临床亚组的生存率.

结论:

转录基因分析揭示了NS-LUAD中明显的,具有预后相关的亚型.
"混沌"亚型代表了一个需要进一步调查的新,积极的实体.
一个60基因的签名具有显著的潜力,以提高NS-LUAD的临床预后.

lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
