IDH2 - Wikipedia
Isocitrate dehydrogenases are enzymes that catalyze the oxidative decarboxylation of isocitrate to 2-oxoglutarate. These enzymes belong to two distinct subclasses, one of which utilizes NAD (+) as the electron acceptor and the other NADP (+).

肿瘤医生应该知道的生物标志物之:IDH1/IDH2 - 知乎
IDH1/2是人类癌症中最常发生突变的代谢基因,干扰细胞代谢和表观调节,促进癌症发生。 【解释】: IDH1和IDH2编码异柠檬酸脱氢酶1和2,催化异柠檬酸氧化脱羧成ɑ-酮戊二酸(α-KG) ,IDH1/2是人类癌症中代谢基因(metabolic genes)发生突变频率最高的,并干扰细胞新陈代谢和表观遗传调控,从而促进肿瘤发生。 IDH1/IDH2病理作用. 新发急性髓系白血病 (AML)中, IDH1/2突变患者多为正常核型、年龄偏大,伴NPM1突变。 IDH2 R140Q突变更多见,对生存 …
IDH突变、表观遗传与靶向治疗 - 知乎 - 知乎专栏
IDH是三羧酸循环的限速酶,能够催化异柠檬酸使之氧化脱羧生成α-KG和CO2。 由IDH催化的这一反应不仅是TCA循环上不可缺少的一个环节,还是细胞内NADPH/NADH等物质的重要来源之一,在细胞氧化还原平衡稳态的保持上也有着重要的作用。 此外,反应产物α-KG除了作为物质代谢的中间产物之外,在表观遗传学、蛋白质翻译后修饰等方面也具有重要的功能。 α-KG的存在对于细胞中一类叫做Fe(II)/α-ketoglutarate(α-KG)-dependent hydroxylase(翻译成中文就是“ …
What Is an Isocitrate Dehydrogenase-2 (IDH2) Mutation?
2022年8月31日 · Here's what to know about the IDH2 mutation, how it is affiliated with a few different conditions, and what it means for treatments. The IDH2 mutation has been detected in about 8 percent to 19 percent of people with acute myeloid leukemia (AML). In AML, the blood-producing cells in the bone marrow become cancerous and fail to mature.

Nature | IDH2抑制剂可促进T细胞分化加强肿瘤免疫 - 知乎
2023年9月29日 · 在嵌合抗原受体(CAR)T细胞的离体培养过程中抑制IDH2可诱导其形成记忆T细胞的特征,并增强其对黑色素瘤、白血病和多发性骨髓瘤的抗肿瘤活性。 抗原刺激和扩增后,大多数CD8+效应T(TE)细胞是短寿命效应细胞(SLECs),但一小部分由记忆前体效应细胞(MPECs)组成的TE细胞将以不依赖抗原的方式存活,并生成长寿中央记忆 T(TCM)细胞。 CD8+ T细胞的强效细胞毒性使几种基于细胞的癌症免疫治疗得到了发展。 不幸的是,转移的细 …

异柠檬酸脱氢酶(IDH)突变的耐药新机制 - 百度
2023年1月2日 · 异柠檬酸脱氢酶(isocitrate dehydrogenase,IDH)是三羧酸循环中催化异柠檬酸转化为α-酮戊二酸(α-KG)的关键代谢酶,也是急性髓细胞白血病(acute myeloidleukemia,AML)中突变最为频繁的肿瘤代谢基因(~20%)。 异柠檬酸脱氢酶突变会催化α-酮戊二酸产生立体异构的致癌代谢物 R-2-羟基戊二酸(R-2HG),同时消耗NADPH产生NADP+。 目前,IDH1突变抑制剂AG-120 (Ivosidenib)和IDH2突变抑制剂AG …
