概括
这项研究使用了门德尔的随机化来将肠道细菌与口腔癌风险联系起来. 某些细菌 (如Burkholderiales) 可能会增加风险,而其他细菌 (如Bacteroidales) 可能会降低风险,需要进一步研究.
科学领域:
- 微生物学 微生物学
- 遗传学 遗传学 是一个
- 在瘤学瘤学.
背景情况:
- 肠道微生物群和口腔癌 (OCC) 之间的因果关系尚不清楚.
- 调查这种联系对于理解OCC病因和开发有针对性的干预措施至关重要.
研究的目的:
- 系统地评估肠道微生物群和口腔癌 (OCC) 之间的因果关系,使用双样本双向门德尔随机化 (MR) 方法.
- 为了确定与OCC风险因果相关的特定细菌种群.
主要方法:

主要成果:
- 布尔克霍德利埃尔类和Alcaligenaceae家族因果关系与OCC.的风险增加有关.
- 细菌群 Bacteroidales,细菌群 Victivallales,细菌群 Clostridiaceae1,细菌群 Clostridiumsensustricto1,细菌群 Eggerthella和细菌群 Holdemanella与降低OCC风险存在因果关系.
- 像Desulfovibrio和Eubacterium fissicatena群这样的特定属也显示出与OCC风险的因果关系.
结论:
- 确定了特定的肠道细菌种群,对口腔癌 (OCC) 风险产生因果作用.
- 伯克霍尔德里亚斯,阿尔卡利根,Desulfovibrio和Eubacterium fissicatena群可能会增加OCC的风险.

What is Monogastric Digestion?
71.1K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Mismatch Repair
4.8K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
