概括
在人体研究中,血清α-klotho水平与骨关节炎 (OA) 有非线性负相关性. 门德尔随机化没有证实OA或膝盖OA的因果关系,但表明对部OA有保护作用.
科学领域:
- 生物化学 生物化学
- 遗传学 是一个遗传学.
- 流行病学 流行病学
背景情况:
- 血清α-klotho与骨关节炎 (OA) 之间的关系尚未得到充分证实,此前的研究主要基于动物模型.
- 这项研究使用人口数据和遗传推断研究了α-klotho和人类OA之间的关联.
研究的目的:
- 为了检查血清α-klotho水平和骨关节炎在大量人类队列之间的横截面关联.
- 使用孟德尔随机化来确定血清α-klotho和OA亚型之间的潜在因果关系.
主要方法:
- 从国家健康和营养检查调查 (NHANES) (2007-2016) 中对12,037名受试者的分析.
- 多变量逻辑回归用于横截面关联分析.
- 两个样本双向门德尔随机化 (MR) 使用逆方差加权 (IVW) 方法进行因果推理.
主要成果:
- 在血清α-klotho和整体OA之间发现了非线性负相关性 (OR=0.77,p < 0.0001).
- 核磁共振分析表明,较高的α-klotho水平与关节骨质炎风险降低有关 (OR = 0.92,P = 9.64×10-3).
- 阿尔法-克洛托和OA或膝盖OA通过MR之间没有建立起因果关系;OA亚型没有对阿尔法-克洛托水平产生因果影响.
结论:
- 血清α-klotho在人体横截面研究中表现出与骨关节炎的非线性负相关性.
- 门德尔随机化发现表明,关节骨关节炎的潜在保护作用,但不证实整体骨关节炎或膝关节骨关节炎的因果关系.

12.4K
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.

3.4K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:20The JAK-STAT Signaling Pathway
8.7K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
