在II期和III期结肠直肠癌中原基HRAS转录水平和整体存活率
在PubMed上查看摘要
概括
此摘要是机器生成的。高HRAS基因表达,通常不被认为是致癌的,与大肠直肠癌 (CRC) 患者的更好的生存率有关. 这一发现挑战了关于RAS基因的现有观念,并建议HRAS作为潜在的预后生物标志物.
科学领域
- 癌症学
- 分子生物学
- 遗传学
背景情况
- 结直肠癌 (CRC) 的突变格局显著影响预后.
- 具有驱动突变的RAS瘤基因如KRAS和NRAS与不良结果有关.
- 病理性HRAS突变很罕见,其预后意义尚不清楚.
研究的目的
- 研究RAS基因表达与CRCII和III阶段的生存结果之间的关联.
- 探索HRAS转录水平在结肠直肠癌中的预后价值.
主要方法
- 来自ORIEN联盟的瘤RNA-Seq数据的回顾性分析.

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.

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...
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.
Three regulatory proteins control their activity:
Guanine nucleotide exchange factors or GEF,
GTPase-activating proteins or GAPs, and
Guanine nucleotide-dissociation inhibitors or GDIs.
The GEF activates the GTPase by exchanging the bound-GDP with GTP. The...
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.
The mTOR pathway or the...
