概括

研究人员确定了一种特定的RASGEF1A基因异型 (ENST00000374459),该异型在乳腺癌患者的血液中减少. 这一发现可能有助于将乳腺癌与健康个体区分开来,并与瘤扩散的增加有关.

科学领域:

分子生物学分子生物学
免疫学免疫学免疫学
在瘤学瘤学.

背景情况:

乳腺癌 (BC) 有各种各样的亚型,影响免疫力,预后和治疗.
非侵入性血液检查提供了有关癌症期间系统免疫力的见解.
在外周血液中识别免疫生物标志物可以帮助检测BC.

研究的目的:

分析BC患者和健康妇女的外周血液单核细胞 (PBMC) 中的转录异形表达.
使用异型级生物信息学识别潜在的BC免疫生物标志物.
调查已识别的异型与临床病理特征的关联.

主要方法:

从BC患者和健康对照对PBMC进行RNA测序和异型水平生物信息学.
使用定量逆转录PCR (qRT-PCR) 验证异型表达.
在较大的队列中与临床病理学数据进行相关性分析.

主要成果:

在BC患者的PBMC中,与健康人群相比,观察到ENST00000374459RASGEF1A异型的显著减少 (p < 0.001).
这种异构体的下调与循环瘤DNA (ctDNA) 和Ki-67的较高水平相关,这是增殖的标志物.
异形分析揭示了疾病特异性的表达变化,这种变化可能会被标准RNA测序遗漏.

结论:

RASGEF1A异型ENST00000374459显示出作为生物标志物的潜力,可以将BC患者与健康个体区分开来.
乳腺癌中ENST00000374459的水平降低与瘤增殖和ctDNA流失的增加有关.
先进的生物信息学,包括异构体分析,对于发现新的,具有生物学意义的,与疾病相关的生物标志物至关重要.

The Ras Gene

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...

Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...
