概括
血清中ursodeoxycholic acid (UDCA),tauroursodeoxycholic acid (TUDCA) 和glucourosodeoxycholic acid (GUDCA) 的水平在患有肌缩性侧面硬化症 (ALS) 的个体中较高. 这项研究在ALS患者中没有发现这些神经保护性胆酸的缺陷.
科学领域:
- 神经科学是一个神经科学.
- 生物化学 生物化学
- 代谢学 代谢学 代谢学
背景情况:
- 内源性性胆酸,包括ursodeoxycholic acid (UDCA),tauroursodeoxycholic acid (TUDCA) 和glucourosodeoxycholic acid (GUDCA),已经证明了潜在的神经保护性质.
- 胆酸代谢的改变与各种神经系统疾病有关,这促使人们对它们在肌缩性侧面硬化症 (ALS) 中的作用进行了调查.
研究的目的:
- 为了研究肌缩性侧面硬化症 (ALS) 诊断和特定胆汁酸的血清度之间的关联.
- 为了比较ALS患者的血清胆酸水平与年龄和性别匹配的健康对照和症状前基因携带者的血清胆酸水平.
主要方法:
- 采用了病例控制研究设计,包括31名ALS患者 (零星和家族) 和49名对照 (症状前基因携带者和健康人群).
- 血清样本使用液态色谱-质谱法 (LC-MS) 进行分析,以量化15种不同的胆酸 (5种非结合,10种结合).
- 通过Wilcoxon-Rank-Sum测试进行了ALS和对照组之间的统计比较.
主要成果:
- 尿液中ursodeoxycholic acid (UDCA),tauroursodeoxycholic acid (TUDCA) 和glucourosodeoxycholic acid (GUDCA) 的水平显示,与对照组相比,ALS组的度趋向于更高 (分别为p=0.04,p=0.06,p=0.04).
- 对于其他测量的胆酸,在ALS和对照组之间没有观察到血清度的显著差异.
- 这项研究包括了与ALS相关的已知遗传变异的参与者,如C9orf72,TARDBP,FUS和CHCHD10.
结论:
- 这些发现表明,在被诊断患有ALS的人群中,特定的爱水胆酸 (UDCA,TUDCA,GUDCA) 可能会升高.
- 该研究没有发现ALS患者中这些潜在的神经保护性胆酸缺乏的证据.
- 需要进一步的研究来阐明这些胆酸在ALS病变发生中的作用以及它们作为治疗点的潜力.

Cross-bridge Cycle
117.5K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Lysosomal Hydrolases
3.8K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Amyloid Fibrils
9.5K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...
