概括

欧米茄-6多不和脂肪酸 (PUFA) 和单不和脂肪酸 (MUFA) 因果上会增加牛皮的风险. 欧米茄-3 PUFA 不会影响牛皮. 针对这些脂肪酸的饮食调整可能有利于牛皮患者.

科学领域:

营养流行病学营养流行病学
遗传流行病学遗传流行病学
皮肤病学皮肤病学

背景情况:

观察性研究表明,不和脂肪酸和牛皮之间存在联系.
以前的研究受到反向因果关系和混因素的限制.
没有确定确定的因果关系.

研究的目的:

使用孟德尔随机化研究不和脂肪酸和牛皮之间的因果关系.
为了区分omega-3 PUFA,omega-6 PUFA和MUFA对牛皮发作的因果关系.

主要方法:

利用孟德尔的随机化分析与来自IEU开放GWAS项目的大规模遗传和表型数据.
包括114,999名Omega-3和Omega-6PUFA受试者的数据,13,535名MUFA受试者,以及4,510个牛皮病例和212,242个对照病例的数据.
采用反变量加权 (IVW) 作为主要方法,以及对异质性和水平变性的灵敏度分析.

主要成果:

欧米茄-6 PUFA 在增加牛皮风险上表现出因果关系 (OR,1.174;p=0.046).
MUFA还在促进牛皮方面表现出因果关系 (OR,1.218;p=0.032).
没有发现omega-3PUFA对牛皮风险有显著的因果关系.

结论:

循环的omega-6PUFA和MUFA被确定为牛皮的因果因素.
欧米茄-3 PUFA 在牛皮的发展中似乎没有因果关系.
旨在降低omega-6PUFA和MUFA水平的治疗策略可能对牛皮管理有效.

Incomplete Dominance

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Pleiotropy

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Mismatch Repair

Mismatch Repair

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.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

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.
GWAS does not require the identification of the target gene involved in...
