代谢调节剂的基因变异,如KEAP1和NRF2 (rs35652124),在乳腺癌组织中显示出不同的分布,可能会影响患者的预后,并突出显示微环境的异质性.
科学领域:
- 在瘤学瘤学.
- 遗传学 遗传学 是一个
- 分子生物学分子生物学
背景情况:
- 乳腺癌是女性癌症死亡的主要原因之一.
- 长期暴露于雌激素与通过半农生产和减弱排毒的致癌性有关.
- 代谢调节基因多态 (KEAP1,NRF2) 可能会影响个体细胞保护.
研究的目的:
- 在乳腺癌患者的血液,瘤和周围组织中基因型KEAP1和NRF2多态.
- 识别体质突变及其与临床病理学数据和预后的相关性.
- 为了研究这些多态的分布模式在不同的组织类型.
主要方法:
- KEAP1 (rs1048290) 和NRF2 (rs35652124, rs6721961, rs6706649) 多态的基因型定型.
- 从血液,周围组织和瘤组织样本中提取DNA.
- 基因型化数据与临床病理特征之间的相关性分析.
主要成果:
- 在血液/周围和瘤/周围组织之间观察到NRF2 rs35652124基因型分布的显著差异 (p=0.023,p=0.041).
- 除了rs35652124之外,其他多态体的组织分布不同,特别是在考虑组织学等级时.
- 与血液和瘤组织相比,周围组织的异构性丧失的趋势被注意到,在2级组织学中变异性更高.
结论:
- 身体突变和多重形态分布的多样性表明乳腺癌中的瘤微环境是异质的和活跃的.
- 这些遗传变化可能会影响乳腺癌的结果.
- 为了预测价值,需要进一步评估组织学等级2,考虑体质突变概况.

Nucleotide Excision Repair
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...
