概括
低LZTR1表达预测肝细胞癌 (HCC) 的早期复发. LZTR1充当瘤抑制剂,其水平可以帮助预测手术后的HCC复发风险.
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:
- 手术后肝细胞癌 (HCC) 复发是一个重大的临床挑战.
- 目前缺乏有效的生物标志物来预测HCC早期复发 (ER).
- 已知瘤抑制剂LZTR1已与HCC发展有关.
研究的目的:
- 调查LZTR1表达和HCC的ER之间的相关性.
- 评估LZTR1对HCC复发的预测能力.
- 阐明LZTR1在HCC细胞增殖和转移中的机制性作用.
主要方法:
- 从101名HCC患者的临床数据中分析了预后因素.
- 采用接收器操作特征 (ROC) 曲线分析来评估LZTR1的预测值.
- 使用HCC细胞系 (Huh7和SK-Hep-1) 的体外实验涉及LZTR1敲击,以研究其对细胞行为的影响.
主要成果:
- 确定了LZTR1,以及α-fetoprotein,瘤数和门静脉瘤血栓,作为与HCC ER相关的独立因素 (P <0.05).
- 与表达较低 (<1.7) (41.4%,P=0.009) 的患者相比,具有高LZTR1表达 (≥1.7) 的患者在一年内无复发率 (73.2%) 显著更高 (41.4%,P=0.009).
- ROC分析表明,LZTR1表达对HCC具有早期预测价值 (AUC=77.9%). 在体外,LZTR1的淘汰促进了HCC细胞的增殖和转移,通过增加RAS/MAPK通路激活和上皮-介质酶过渡.
结论:
- 在HCC的病理进展中,LZTR1作为瘤抑制剂起作用.
- LZTR1表达是HCC患者早期复发的潜在预测生物标志物.
- 向LZTR1可能为缓解HCC进展和复发提供治疗策略.

Non-LTR Retrotransposons
11.8K
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...

lncRNA - Long Non-coding RNAs
8.9K
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...
