HDAC11是唯一的IV类HDAC,是骨髓增生性肿瘤的治疗点而非HDAC6。

Hdac11在癌基因诱导的造血过程中起关键作用,但在正常造血过程中无相同作用。

摘要:

蛋白质乙酰化是癌症发生的重要因素。组蛋白去乙酰化酶6 (HDAC6)调控JAK2的翻译和蛋白质的稳定性,并与JAK2驱动的疾病有关,最典型的例子是骨髓增生性肿瘤(MPNs)。

通过新型的高选择性HDAC抑制剂和基因缺陷小鼠模型,研究人员发现是HDAC11对致癌性JAK2驱动的MPN细胞和患者样本的增殖和存活必不可少,而非HDAC6。值得注意的是,HDAC11在原始干细胞中有多种表达方式,主要由谱系决定。虽然Hdac11缺乏可以通过嵌合BM重组实现正常的造血干细胞和祖细胞分化,但在MPLW515L-MPN小鼠模型中,Hdac11缺乏症会显著减少异常的巨核细胞的数量、改善脾结构、减少纤维化、提高小鼠存活率。

因此,HDAC11抑制剂是治疗MPN患者的一种有吸引力的治疗方法。虽然JAK2抑制剂疗法对MPN患者有很大的临床益处,但为了逆转MPN病理和控制恶性造血,还是需要找到替代的治疗靶点。本研究强调了HDAC11作为一种独特的靶分子,具有MPN治疗潜能。
