- 为了确定体质DELs,暴露和NMSC中的基因通路失调之间的相互作用.
- 基于这些分子发现,探索潜在的治疗点.
主要方法:
- 对NMSC瘤组织 (n=32) 和配对的血液样本进行比较分析.
- 从单独的队列中分析健康的皮肤和配对的血液样本 (n=16).
- 识别与NMSC相关的小删除 (DEL).
- 转录形状分析以评估关键通路 (例如TGF-β,IL-17,PD-L1) 中的差异性基因表达.
- 检查DELs,暴露水平和基因通路表达之间的相互作用.
主要成果:
- 确定了与NMSC相关的小删除 (DEL),其中许多位于短串重复 (STR) 区域.
- 包括TGF-β,IL-17和PD-L1在内的途径中的差异性基因表达与体质DEL和暴露有显著的相互作用.
- 在低的病例中,APC DEL与炎症T细胞基因增加了8.9倍;在高的病例中,APC DEL增加了5.8倍.
结论:
- 这项研究是第一个报告NMSC组织体质DEL,暴露和失调的基因通路之间的显著关联的研究.
- 这些发现强调了NMSC发育中的遗传变化和环境因素之间的相互作用.
- 这些见解可能会为针对性治疗的患者分层提供信息,包括PD-L1,IL-17和TGF-β抑制剂.

Gene-Environment Interactions
248
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

The Tumor Microenvironment
6.5K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
