概括
长非编码RNA RP11 (RP11) 在肝细胞癌 (HCC) 中高度表达,促进瘤生长并表明预后不佳. 沉默RP11抑制HCC细胞增殖并诱导细胞亡,这表明它作为潜在的诊断标记物的作用.
科学领域:
- 分子生物学分子生物学
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
背景情况:
- 肝细胞癌 (HCC) 是一个主要的全球健康问题.
- 长非编码RNAs (lncRNAs) 在各种癌症中发挥关键作用,包括HCC.
- 在HCC中,lncRNA RP11-556E13.1 (RP11) 的特定功能和临床意义在很大程度上仍未被探索.
研究的目的:
- 阐明lncRNA RP11在肝细胞癌中的功能作用.
- 研究RP11在HCC患者中的临床意义和预后价值.
主要方法:
- 在HCC和相邻组织中使用微阵列进行LncRNA和mRNA表达概况.
- 定量实时PCR (sqRT-PCR) 用于验证RP11表达式.
- 在HCC细胞系中,siRNA介导的RP11的淘汰.
- 细胞增殖,细胞亡和细胞循环测试以确定RP11的功能.
- 西方涂抹测试以评估蛋白质表达变化.
- 生物信息分析 (GO和KEGG路径丰富) 探索潜在的机制.
主要成果:
- 与邻近组织相比,HCC组织中的RP11显著上调 (折叠变化=20.24,p<0.05).
- 较高的RP11表达与较大的瘤大小,较差的分化和较低的HCC患者的整体存活率相关 (p <0.05).
- RP11的淘汰抑制了HCC细胞增殖,诱导了亡,并导致G1/S停止,增加了分裂的PARP1和分裂的caspase-3水平.
结论:
- lncRNA RP11作为一种瘤基因,促进肝细胞癌的进展.
- RP11作为HCC的潜在预后生物标志物.

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...

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...

4.5K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
