摘要: 异柠檬酸脱氢酶1(IDH1)存在于细胞质和过氧化物酶体中,是三羧酸循环中的关键限速酶。近年来研究发现IDH1突变存在于多数胶质瘤中,其代谢产生的大量2羟戊二酸可能作为潜在致癌物参与胶质瘤的发生,同时与患者预后的改善密切相关。IDH1突变有望作为新型基因标志指导临床胶质瘤的治疗。

Abstract: Isocitrate dehydrogenase 1 (IDH1), a key ratelimiting enzyme in tricarboxylic acid cycle, is found within the cytoplasm and peroxisomes. In recent years, IDH1 mutation is discovered in most glioma and its large scale metabolites, 2hydroxyglutarate, may be involved in tumor as potential carcinogens, and is shown to be closely related to better patients′ survival as well. IDH1 mutation is anticipated to be a novel genetic biomarker which will guide the treatments of clinical glioma.
