概括
在缺乏凝聚力的胃癌 (GC) 中,HIV-1 Tat 交互蛋白 2 (HTATIP2) 的下调. 过度表达HTATIP2与早期疾病,转移率降低和生存率提高有关,这表明它有可能成为预后标志物.
科学领域:
- 分子生物学分子生物学
- 在瘤学瘤学.
- 基因组学就是基因组学.
背景情况:
- 胃癌 (GC) 呈现出不同的亚型,包括缺乏凝聚力的癌症 (PCC) 和分化良好的管状腺癌 (WD).
- 这些亚型之间的转录组差异尚未完全阐明,这影响了对GC进展和预后的理解.
- 艾滋病毒-1 Tat 交互蛋白2 (HTATIP2) 在胃癌发生中的作用在很大程度上仍未被探索.
研究的目的:
- 为了比较胃癌的PCC和WD亚型的转录组.
- 为了研究HTATIP2在胃癌患者的预后意义.
- 探索HTATIP2在胃癌细胞行为中的功能作用.
主要方法:
- 下一代测序在8个GC手术样本 (5WD,3PCC) 和3个GC细胞系 (1WD,2PCC) 上进行.
- 免疫组织化学被用来验证HTATIP2表达.
- 功能性测试涉及HTATIP2过度表达 (OE),使用Kaplan-Meier图表和PrognoScan数据库进行生存分析.
主要成果:
- 与WD相比,HTATIP2,ESRP1,GRHL2,ARHGEF16,CKAP2L和ZNF724在PCC中的表达显著减少.
- 过度表达HTATIP2与早期胃癌 (EGC),淋巴结转移减少和TNM较低阶段有关.
- HTATIP2 OE与更好的生存率以及癌细胞迁移和入侵的减少相关,可能是通过减少牛/牛的表达.
结论:
- 在缺乏凝聚力的胃癌中,HTATIP2的下调显著.

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...

3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:20The Retinoblastoma Gene
4.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

02:23Abnormal Proliferation
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...
