Histone deacetylases (HDACs) are a key component of the epigenetic machinery regulating gene expression, and behave as oncogenes in several cancer types, spurring the development of HDAC inhibitors (HDACi) as anticancer drugs. This review discusses new results regarding the role of HDACs in cancer and the effect of HDACi on tumour cells, focusing on haematological malignancies, particularly acute myeloid leukaemia. Histone deacetylases may have opposite roles at different stages of tumour progression and in different tumour cell sub-populations (cancer stem cells), highlighting the importance of investigating these aspects for further improving the clinical use of HDACi in treating cancer.
组蛋白去乙酰化酶(HDACs)是调控基因表达的表观遗传机制的关键组成部分,并且在多种癌症类型中发挥癌基因的作用,这促使人们研发组蛋白去乙酰化酶抑制剂(HDACi)作为抗癌药物。本综述讨论了关于HDACs在癌症中的作用以及HDACi对肿瘤细胞影响的新结果,重点关注血液系统恶性肿瘤,尤其是急性髓系白血病。组蛋白去乙酰化酶在肿瘤进展的不同阶段以及不同肿瘤细胞亚群(癌症干细胞)中可能具有相反的作用,这凸显了研究这些方面对于进一步改善HDACi在癌症治疗中的临床应用的重要性。
