Abstract

In recent years, it is found that the classical IKKα and IKKβ pathway were closely relates with hematological tumors, except the classical pathogenesis, moreover the classical IKKβ pathway is deeply studied. The studies indicated that the IKKβis activated to phosphorylate the NF-κB through multiple cascades under the effect of extracellular IL-6, TNF-α and other stimulating factors. At the cellular level, the classical IKKβcan promote the tumor cell survival and proliferation, reduce the cell apoptosis, and promote the angiogenesis and cell transfer. Although the classical IKKα plays a role in regulating IKKβ activity, but its role in non-classical pathway is more prominent. This review briefly summarizes the latest advance of researches on the pathogenesis of hematological malignancies in term of IKKα and IKKβpathway, so as to provide the theoretic basis for deeply understanding and studying the pathogenesis of hematologic tumors. At present, blocking the classical IKKα and IKKβ pathway has become a new target for treatment of hematological tumors, moreover, some specific inhibitor for IKKα and IKKβpathway have been developed, for example, LY2409881, BMS 345541 and so on. Most of these drugs are in clinical trials and display some good anti-tumor effects.

题目: 经典途径IKKα与IKKβ在血液肿瘤中的作用机制及阻断其作用的药物治疗的最新研究进展.

摘要: 近年来,除了经典的发病机制外,发现经典的IKKα与IKKβ途径在血液肿瘤中关系密切,且对经典的IKKβ途径的研究较为深入。研究表明,在胞外IL-6、TNF-α等刺激因子作用下,IKKβ被激活,通过多种级联反应使NF-κB磷酸化,在多发性骨髓瘤中引起细胞周期蛋白D表达增加,在慢性髓系白血病中引起抗凋亡基因BCL-x(L)表达增强;在细胞层面上,IKKβ途径促进肿瘤细胞生存及增殖,减少细胞凋亡,促进血管生成及细胞迁移;而经典的IKKα虽在调节IKKβ活性方面起到作用,但在非经典途径中作用更突出。本文就此对血液肿瘤发病机制的最新研究进展进行综述,为更加深入认识血液肿瘤发病机制及研究方向提供理论依据。目前,阻断经典的IKKα与IKKβ途径已成为治疗血液肿瘤的一个新的作用靶点,已研发出一些特异性IKKα及IKKβ抑制剂,如LY2409881、BMS-345541等,大部分药物正处于临床试验阶段,具有良好的抗肿瘤作用.
