概括
在食道和胃癌中对温度敏感的TP53突变没有显著影响生存率,尽管出现了更糟糕的结果的趋势. 需要进一步的研究,以了解这些温度敏感TP53突变的独特预后价值.
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:
- 在食道癌 (EC) 和胃癌 (GC) 中,TP53突变很常见.
- 温度敏感 (TS) TP53突变在体温下是不活跃的,但在较低的温度下可以被重新激活.
- TS TP53突变可能提供独特的治疗或预后见解.
研究的目的:
- 研究EC和GC与TSTP53突变的趋势和结果.
- 为了确定TS TP53突变是否与非TS TP53突变相比具有不同的预后形状.
- 评估TS TP53状态和EC和GC患者的整体存活时间之间的关联.
主要方法:
- 利用cBioportal识别了1924名EC或GC和TP53突变患者.
- 根据TP53温度灵敏度 (TS与非TS) 分层的患者.
- 分析了生存结果,并根据突变状态,癌症阶段和其他临床因素对比了人群.
主要成果:
- 在TS/非TSTP53状态和巴雷特食道,癌症阶段或种族之间没有发现任何关联.

02:27Background and Environment Affect Phenotype
6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

7.3K
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...
