概括
这项研究发现,在印度非小细胞肺癌 (NSCLC) 患者中,microRNA-193b的调节显著上升,这表明其作为非侵入性生物标志物的潜力. 为了验证微RNA作为可靠的诊断工具,进一步的特定人群分析是必不可少的.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 生物标志物发现发现
背景情况:
- 非小细胞肺癌 (NSCLC) 是全球癌症死亡的主要原因.
- 目前的NSCLC早期检测方法存在局限性,包括高错误阳性率和辐射暴露.
- 需要非侵入性生物标志物来改善NSCLC的早期检测.
研究的目的:
- 在印度人群中验证循环的微RNA (miRNA) 作为NSCLC的非侵入性生物标志物.
- 研究NSCLC中特定循环miRNA和临床病理参数之间的相关性.
- 评估选择的miRNAs在区分NSCLC与对照的诊断潜力.
主要方法:
- 分析了101名NSCLC患者和28名对照组的血清样本.
- 测量了四种循环中的microRNAs (miR-193b,miR-301a,miR-7和miR-25) 的表达水平.
- 对miR-193b进行了接收器操作特征 (ROC) 曲线分析.
主要成果:
- 与对照组相比,MiR-193b在NSCLC患者中显示出显著的上调调节 (P=0.034).
- 在NSCLC中,miR-7也受到上调,而miR-25和miR-301a则受到下调,尽管没有达到统计学意义.
- 对于miR-193b的ROC分析表明AUC为0.636 (P=0.036),这表明诊断潜力.
结论:
- 在印度NSCLC群体中,循环的miR-193b被显著上调.

3.0K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

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...

3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
