概括

这项研究在COVID-19患者中识别了350多种新型仿制RNA,为病毒感染提供了潜在的生物标志物. 这些发现增强了我们对SARS-CoV-2的理解.

科学领域:

基因组学就是基因组学.
分子生物学分子生物学
病毒学病毒学

背景情况:

COVID-19 (冠状病毒疾病2019) 仍然是一个全球健康挑战,对其对宿主基因表达的影响的理解不完全.
转录组分析对于了解宿主对SARS-CoV-2 (严重急性呼吸系统综合征冠状病毒2) 感染的反应至关重要.
化学RNA表达是病毒感染中宿主转录组学研究不足的一个方面.

研究的目的:

在COVID-19患者的全血中特征化基因组RNA.
为了识别与SARS-CoV-2感染相关的新型仿制RNA.
探索仿制RNA作为COVID-19生物标志物的潜力.

主要方法:

来自178名COVID-19患者的全血转录组的分析.

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...
