- 分子生物学分子生物学
- 遗传学 是一个遗传学.
背景情况:
- 在全球范围内,结肠癌 (CC) 的发病率正在增加.
- 长非编码RNAs (lncRNAs) 在基因调节和癌症发展中起着至关重要的作用,包括CC.
研究的目的:
- 调查特定 lncRNAs 在结肠癌发展中的功能.
- 为了识别潜在的 lncRNA 生物标志物用于 CC 诊断和治疗.
主要方法:
- 对CC组织中差异表达的lncRNAs (DElncRNAs) 和mRNAs (DEmRNAs) 的GEO数据集 (GSE104836) 的分析.
- 通过在31个结对的瘤和相邻的正常组织中评估表达水平,选择和验证FENDRR和LINC00092.
- 使用GEPIA2的生存分析和通过ROC方法的诊断能力评估.
- 使用甲基化特异性PCR (MSP) 调查促进体甲基化模式.
主要成果:
- 在所有阶段的结肠癌组织中,FENDRR和LINC00092的表达显著下降.

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...

MicroRNAs
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...

Non-LTR Retrotransposons
11.4K
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...
