概括
一项双向的门德尔随机化研究发现,增加腰围,是代谢综合征的一个组成部分,因果上会增加结直肠癌的风险. 然而,代谢综合征整体及其其他组成部分并没有显示与结直肠癌的因果关系.
科学领域:
- 遗传学 是一个遗传学.
- 流行病学 流行病学
- 代谢障碍 代谢障碍 代谢障碍
背景情况:
- 观察性研究表明,代谢综合征 (Mets) 和结直肠癌 (CRC) 之间存在联系.
- 梅茨和CRC之间的因果关系尚不清楚.
- 调查单个Mets组件的因果作用至关重要.
研究的目的:
- 确定代谢综合征及其组成部分是否因果关系影响结肠直肠癌风险.
- 进行双向门德尔随机化分析以评估因果关系.
- 为了澄清肥胖和结直肠癌之间的病因关系.
主要方法:
- 利用了Mets的全基因组关联数据,其组成部分 (高血压,腰围,禁食血糖,血清甘油三,高密度脂蛋白胆固醇) 和结直肠癌.
- 采用双向门德尔随机化 (MR) 技术.
- 应用了Benjaminini-Hochberg的多重校正来进行统计分析.
主要成果:
- 在增加腰围 (WC) 和结直肠癌 (CRC) (OR=1.35,P=0.0096) 之间发现了显著的遗传预测因果关系.
- 对于其他Mets成分 (高血压,禁食血糖,甘油三,高血糖) 或整体Mets影响CRC.没有发现有意义的因果关系证据.
- 双向分析表明,CRC对Mets或其组件没有因果关系.
结论:
- 腰围的增加是代谢综合征中肥胖的一个关键指标,因果关系与结直肠癌的风险增加有关.
- 代谢综合征及其其他组成部分似乎对结直肠癌没有因果关系.
- 因果关系是单向的,从肥胖到结直肠癌,而不是相反.

02:03Law of Independent Assortment
55.7K
While Mendel’s Law of Segregation states that the two alleles for one gene are separated into different gametes, a different question of how different genes are inherited remains. For example, is the gene for tall plants inherited with the gene for green peas? Mendel asked this question by experimenting with a dihybrid cross; a cross in which both parents are homozygous for two distinct traits resulting in an F1 generation that are heterozygous for both traits.

38.2K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

4.9K
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.

13.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
