概括

在15%的肺腺癌患者中发现RICTOR突变,通常与EGFR,KRAS和TP53变异同时发生. 这确定了非小细胞肺癌 (NSCLC) 中的一个独特的分子子组.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
基因组学就是基因组学.

背景情况:

瑞克托是mTORC2复合体的关键组成部分,调节AKT信号传递,并参与瘤发育.
虽然已知RICTOR放大,但它在非小细胞肺癌 (NSCLC) 中的突变模式和分子背景需要进一步表征.

研究的目的:

研究转移性肺腺癌中RICTOR突变的流行率和共同变异模式.
定义与NSCLC中RICTOR突变相关的分子子组.

主要方法:

对137名转移性肺腺癌患者的回顾性分析.
使用下一代测序 (NGS) 进行基因组分析.
编目致病性变化并比较共突变模式.

主要成果:

在15%的患者中发现了RICTOR突变.
突变经常与EGFR (65%),KRAS (55%) 和TP53 (45%) 一起发生.
观察到不常见的EGFR变体 (G719X,外显子20插入) 的丰富以及其他同时发生的变化,如PIK3CA,STK11,KEAP1,HER2和BRAF V600E.

结论:

在肺腺癌中,RICTOR突变定义了一个独特的分子子组.
这一小组的特点是与EGFR,KRAS,TP53频繁共发生,以及各种各样的基因组变化.
需要在更大的队列中进行进一步的研究,以了解RICTOR在复杂的致癌环境中的作用.

关键词:

共同突变是一种共同突变.基因组特征分析基因组特征分析肺部腺癌瘤是肺部腺癌.在MTORC2中,我们使用了MTORC2.这就是RICTOR突变.

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

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...
