概括
微RNA-371a-3p (M371) 是丸生殖细胞瘤 (GCTs) 的一种特定生物标志物. 这项研究在其他癌症中发现M371的错误阳性率非常低,这证实了其对GCT检测的高特异性.
科学领域:
- 在瘤学瘤学.
- 分子诊断学 分子诊断学
- 生物标志物研究 生物标志物研究
背景情况:
- microRNA-371a-3p (M371) 被认为是丸生殖细胞瘤 (GCT) 的高度敏感和特定的血清生物标志物.
- 关于M371在非丸性恶性瘤中的表达存在有限的数据.
- 了解M371在其他癌症中的表达对于其临床应用至关重要.
研究的目的:
- 在患有非丸性恶性瘤 (NTMs) 的患者中研究M371的表达水平.
- 评估M371测试在其他癌症存在时检测GCT的特异性.
主要方法:
- 在137名NTM患者中量化了12种癌症类型的血清M371水平,使用IVDR认证的M371-Test.
- 在NTM患者,GCT患者 (n=20) 和健康男性对照者 (n=20) 之间比较了M371水平.
- 用描述性统计数据分析了M371的中位数水平和升高率.
主要成果:
- 在患有NTM的患者中观察到5.84%的低虚假阳性率 (FPR).

MicroRNAs
21.2K
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...

lncRNA - Long Non-coding RNAs
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...
