概括
在代61的RAS突变在转移性结直肠癌 (mCRC) 中很少见. 这些突变与mCRC患者的整体存活率降低和腹膜或卵巢扩散的增加有关.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 遗传学 是一个遗传学.
背景情况:
- RAS突变是各种癌症的关键驱动因素,但在转移性结直肠癌 (mCRC) 中,代码子61突变并不常见.
- 最近的发现表明,在患有抗EGFR疗法耐药性的患者中,在循环瘤DNA (ctDNA) 中出现codon 61 RAS突变.
研究的目的:
- 在转移性结肠直肠癌中研究代码子61RAS突变的临床特征和预后意义.
- 为了比较具有codon 61 RAS突变的患者与各种比较组的结局.
主要方法:
- 在2013年至2021年期间治疗的50名具有codon 61 RAS突变的mCRC患者的回顾性分析.
- 与648名患有codon 61 RAS野生型mCRC的患者进行比较,并与非codon 61 RAS突变,BRAF V600E突变和RAS/BRAF野生型队列进行比较.
- 总生存 (OS) 是预后评估的主要终点.
主要成果:
- 与其他组相比,Codon 61 RAS-突变的mCRC显示腹或卵巢转移的频率 (54%) 显著更高.
- 与RAS/BRAF野生型患者 (36.0个月) 相比,具有codon 61 RAS突变的患者的平均整体存活时间较短 (26.9个月).
- 在codon 61 RAS突变和非codon 61 RAS突变或BRAF V600E突变队列之间没有发现显著的OS差异.
结论:
- 在mCRC中的Codon 61 RAS突变与一个独特的临床表型有关,包括增加腹和卵巢转移.
- 这些突变对转移性结直肠癌患者的整体生存期有负面的预后影响.
- 这些发现突显了识别codon 61 RAS突变对于理解mCRC进展和治疗耐药性的重要性.

The Ras Gene
6.2K
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.

Abnormal 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...

Small GTPases - Ras and Rho
3.9K
Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.

The 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,...

Rous Sarcoma Virus (RSV) and Cancer
5.1K
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.

mTOR Signaling and Cancer Progression
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.
