科学领域:

生物化学生物化学
遗传学是一个遗传学.
代谢障碍代谢障碍代谢障碍

背景情况:

素缺乏症 (CD) 是一种复杂的线粒体疾病,具有与年龄有关的明显表现:新生儿肝内胆固醇症 (NICCD),发育不良和脂质失调症 (FTTDCD) 和青少年/成人CD (AACD).
由于线粒体中酸盐/酸盐载体2 (citrin/SLC25A13) 的功能障碍,CD会损害酸盐-酸盐穿和尿素循环,导致复杂的代谢干扰.
尽管CD在亚洲人群中很常见,但CD是泛种族的,而且诊断严重不足.

检查与CD相关的遗传变异及其病原性影响.
评估临床前模型和治疗开发工作.

主要成果:

素在基质运输中的作用是复杂的,最近的数据质疑调节.
不同的致病变体有助于CD,对其机制的洞察力不断演变.
在开发CD的临床前模型和治疗干预措施方面取得了进展.

结论:

对素的运输机制和致病变体的进一步研究至关重要.
开发有效的临床前模型对于推进CD治疗至关重要.
治疗开发的持续努力有望为管理素缺乏症提供希望.

Products of the Citric Acid Cycle

Products of the Citric Acid Cycle

The cells of most organisms—including plants and animals—obtain usable energy through aerobic respiration, the oxygen-requiring version of cellular respiration. Aerobic respiration consists of four major stages: glycolysis, pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation. The third major stage, the citric acid cycle, is also known as the Krebs cycle or tricarboxylic acid (TCA) cycle.

Lysosomal Hydrolases

Lysosomal Hydrolases

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,...
