概括
结肠癌相关的转录-1 (CCAT1) 在结肠直肠癌 (CRC) 患者中显著升高,为早期诊断和预后提供了一个有前途的生物标志物. 它的表达在检测CRC方面超过CEA和CA 19-9的表达.
科学领域:
- 表观遗传学和分子瘤学
- 发现了胃肠道癌症的生物标志物
背景情况:
- 大肠直肠癌 (CRC) 具有显著的死亡风险,特别是在晚期诊断时.
- 表观遗传因素,包括长非编码RNAs (lncRNAs),在CRC启动,进展和转移中发挥着至关重要的作用.
- 结肠癌相关转录-1 (CCAT1) 是CRC中的失调的lncRNA,具有作为非侵入性诊断标记物的潜力.
研究的目的:
- 评估结直肠癌中CCAT1表达的诊断和预后价值.
- 为了比较CCAT1表达水平与已确定的瘤标记物,癌胚抗原 (CEA) 和碳水化合物抗原19-9 (CA 19-9).
主要方法:
- 分析了41名CRC患者,39名良性结肠直肠疾病患者和20名健康对照患者的血清样本.
- 使用实时聚合酶链反应 (RT-PCR) 来量化CCAT1表达.
- 血清CEA和CA 19-9水平通过自动免疫测试进行测量.
主要成果:
- 与良性疾病和对照组相比,CRC患者的CCAT1表达显著上调 (分别为p = 0.009和p < 0.001).
- 在良性疾病组与对照组 (p = 0.004) 中也观察到高CCAT1表达.
- 血清CEA水平在CRC患者中显著更高,而CA 19-9在不同组之间没有显著差异.
结论:
- 对于早期诊断和结直肠癌的预后,CCAT1比CEA和CA 19-9更有效的生物标志物.
- 这些发现突显了CCAT1作为CRC管理中的一个有价值的非侵入性生物标志物的潜力.

lncRNA - 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...

Real Time RT-PCR
57.3K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
