概括
核细胞和关联蛋白1 (NUSAP1) 在肺腺癌中过度表达,特别是在吸烟者中,与预后不佳相关. 这表明NUSAP1是肺癌进展和生存结果的关键因素.
科学领域:

- 分子生物学分子生物学
- 遗传学 遗传学 是一个
背景情况:
- 核细胞和关联蛋白1 (NUSAP1) 对于细胞分裂至关重要,其表达与患者的不良结果有关.
- 了解NUSAP1在肺癌中的作用对于开发向疗法和改善患者预后至关重要.
研究的目的:
- 研究NUSAP1在肺癌中的表达模式和预后意义.
- 探索与肺腺癌中NUSAP1相关的分子网络,特别是与吸烟状况相关.
主要方法:
- 使用了多个公共数据库 (KM Plotter,TNMplot,UALCAN,GEPIA2,TIMER 2.0,等等) 分析肺癌组织中的NUSAP1基因表达与正常组织的基因表达.
- 与临床结果相关的NUSAP1表达,包括整体生存 (OS),第一次进展 (FP) 和后进展生存 (PPS).
- 研究了与其他分子因素的关联,如lncRNA-TMPO-AS1,miRNA hsa-let-7b-5p,E2F1,细胞周期检查点和瘤透免疫细胞.
主要成果:
- 发现NUSAP1在肺腺癌 (LUAD) 和状细胞癌 (LUSC) 中都过度表达.
- 高NUSAP1表达与LUAD患者的低OS,FP和PPS显著相关 (HRs从1.48到1.96不等),特别是在吸烟者中.
- 过度表达lncRNA-TMPO-AS1和高NUSAP1水平与LUAD吸烟者的预后不佳有关,可能由hsa-let-7b-5p海绵介导,并与细胞周期进展和CD4+免疫细胞透有关.
结论:
- 高水平的E2F1,NUSAP1和TMPO-AS1导致肺腺癌吸烟者的预后更差.

lncRNA - Long Non-coding RNAs
9.0K
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...

The Nucleolus
9.2K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
