概括
克里米亚 - 刚果出血热 (CCHF) 病变可能涉及长非编码RNA NRAV. 较高的NRAV表达与患者中CCHF严重程度和致命结局有显著的相关性.
科学领域:
- 病毒学 病毒学
- 分子生物学分子生物学
- 遗传学 是一个遗传学.
背景情况:
- 克里米亚 - 刚果出血热 (CCHF) 是一种严重的动物性疾病,由CCHF病毒引起.
- 目前尚不清楚CCHF病变的确切机制.
- 长非编码RNAs (lncRNAs) 与病毒性疾病进展有关,但它们在CCHF中的作用尚未研究.
研究的目的:
- 为了研究两种lncRNAs,NRAV和Lethe的表达水平,在被诊断为CCHF的患者中.
- 为了确定NRAV和Lethe表达是否与CCHF疾病严重程度和患者结局相关.
主要方法:
- 分析了80名CCHF患者的血液样本.
- 使用定量实时聚合酶链反应 (qPCR) 来测量NRAV和Lethe表达.
- 患者按疾病严重程度 (轻度,中度,严重) 和生存状态 (幸存者,非幸存者) 分层.
主要成果:
- 与中度和轻度病例相比,严重的CCHF病例中的NRAV表达显著增加 (分别为21.86x和22.74x高).

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...

8.5K
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...
