骨髓增生性肿瘤(MPN)是克隆性造血祖细胞疾病,其特征是一种或多种造血谱系(骨髓、红细胞和/或巨核细胞)的增殖。MPN包括八种血液系统疾病:慢性髓性白血病(CML)、真性红细胞增多症(PV)、原发性血小板增多症(ET)、原发性骨髓纤维化(PMF)、系统性肥大细胞增多症(SM)、慢性嗜酸性粒细胞白血病(CEL,NOS)、慢性嗜酸性粒细胞白血病(CNL)和无法分类的MPN(MPN,U)。MPN的治疗干预包括使用酪氨酸激酶抑制剂(TKI)治疗BCR-ABL 1 + CML和JAK 2抑制剂治疗PV、ET和PMF。组蛋白去乙酰化酶抑制剂(HDACi)是一类新型药物,其能够改变组蛋白和非组蛋白蛋白的乙酰化状态,从而影响肿瘤细胞中的细胞功能,包括增殖、分化、免疫应答、血管生成和存活。初步研究表明,HDACi当与酪氨酸激酶或JAK 2抑制剂组合使用时,可以克服对后一种药剂的抗性并增强对MPN细胞的促凋亡作用。本文综述了HDACi作为MPN潜在治疗药物的临床前和临床研究。
Myeloproliferative neoplasms (MPN) are clonal haemopoietic progenitor cell disorders characterized by the proliferation of one or more of the haemopoietic lineages (myeloid, erythroid and/or megakaryocytic). The MPNs include eight haematological disorders: chronic myelogenous leukemia (CML), polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF), systemic mastocytosis (SM), chronic eosinophilic leukemia, not otherwise specified (CEL, NOS), chronic neutrophilic leukemia (CNL), and unclassifiable MPN (MPN, U). Therapeutic interventions for MPNs include the use of tyrosine kinase inhibitors (TKIs) for BCR-ABL1+ CML and JAK2 inhibitors for PV, ET and PMF. Histone deacetylase inhibitors (HDACi) are a novel class of drugs capable of altering the acetylation status of both histone and non-histone proteins, thereby affecting a repertoire of cellular functions in neoplastic cells including proliferation, differentiation, immune responses, angiogenesis and survival. Preliminary studies indicate that HDACi when used in combination with tyrosine kinase or JAK2 inhibitors may overcome resistance to the latter agents and enhance the pro-apoptotic effects on MPN cells. This review provides a review of pre-clinical and clinical studies that have explored the use of HDACi as potential therapeutics for MPNs.
