概括
长非编码RNA LINC00921 在肺腺癌 (LUAD) 中是下调的. 较低的LINC00921表达与较短的存活率和瘤免疫力改变有关,这表明其作为LUAD生物标志物的潜力.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 基因组学就是基因组学.
背景情况:
- 肺腺癌 (LUAD) 通常在晚期呈现,需要新的生物标志物用于早期检测和预后.
- 长非编码RNAs (lncRNAs) 与瘤发生有关,但LINC00921在LUAD中的作用尚不清楚.
研究的目的:
- 研究LINC00921在肺腺癌中的表达,诊断价值和预后意义.
- 探索LINC00921表达与瘤突变负担,免疫细胞透以及LUAD中的潜在治疗点之间的关系.
主要方法:
- 利用了来自癌症基因组图谱 (TCGA) 的基因表达数据,用于LUAD患者.
- 进行了诊断能力,生存,瘤突变负担和免疫细胞透分析.
- 使用实时聚合酶链反应对血液样本进行验证的结果.
主要成果:
- 与正常组织相比,LINC00921表达在LUAD瘤组织中明显较低.
- 较低的LINC00921表达与中位生存时间缩短和免疫细胞透率降低有关.
- 在高和低的LINC00921表达组之间观察到瘤突变负担的差异,影响了生存率.
结论:
- LINC00921 作为肺腺癌的潜在诊断生物标志物.
- 它的表达水平与患者预后,瘤微环境特征和突变格局有关.
- 与甘-3-酸盐脱酶相关的药物可能为LUAD提供治疗潜力.

02:39lncRNA - Long Non-coding RNAs
8.6K
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...

11.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
