中心点:

CCND1与HDAC1/2结合,阻碍其招募至SOX11启动子,从而增强组蛋白乙酰化和SOX11的转录。

STAT3通过与SOX11基因的启动子和增强子直接相互作用来抑制SOX11的转录。

摘要:

神经转录因子SOX11在经典套细胞淋巴瘤(MCL)中常高表达,但在较为惰性的MCL亚型中不表达。虽然SOX11是该难治疗的恶性肿瘤的一个重要的预后标志物,但其异常表达的机制还基本不明确。

Atish Mohanty等人发现在多种人类CL细胞系中,CCND1异位表达导致SOX11的转录增加,这与乙酰化的组蛋白H3K9和H3K14(H3K9/14Ac)增加相关。通过RNA干扰敲除或HDAC抑制剂vorinostat抑制HDAC1或HDAC2后,也可观察到H3K9/14Ac和SOX11表达增加。

在机制上,研究人员发现CCND1与SOX11位点的HDAC1和HDAC2相互作用并相互隔离,导致SOX11上调。此外,本研究还发现在MCL细胞系中、原发性肿瘤和患者来源异种移植物中,磷酸化的Y705 (pY705) STAT3与SOX11表达存在潜在负相关。

在功能上,通过抑制上游的Janes激酶(JAK)1/2或通过敲除STAT3来失活STAT3,可增加SOX11的表达,而白介素21(IL21)诱导的STAT3激活或过表达激活形态的STAT3则可降低SOX11的表达。此外,在SOX11阳性的MCL细胞中,通过RNA干扰或通过IL21治疗间接直接靶向SOX11可诱导细胞毒性。

总而言之,本研究表明CCND1和STAT3参与SOX1表达的调控,为MCL治疗提供新的方向。

Lancet oncol:VR-CAP疗法相比R-CHOP可显著延长套细胞淋巴瘤患者的总体存活期

LYM-3002研究,在不适合进行移植的未治疗过的新确诊的套细胞淋巴瘤患者中对比硼替佐米联合利妥昔单抗、环磷酰胺、阿霉素和强的松(VR-CAP)和利妥昔单抗、环磷酰胺、阿霉素、长春新碱和强的松(R-CHOP)两种一线疗法的疗效和安全性。现研究人员对达到主要的无进展存活期结点后,长期随访阶段患者的最终总体存活期和安全预后结果进行报告。LYM-3002是在28个国家的128个临床中心开展的一项随机化的

2018 BSH指南:套细胞淋巴瘤的管理

2018年5月,英国血液病学学会(BSH)发布了套细胞淋巴瘤的管理指南,指南主要目的是面向临床医生针对套细胞淋巴瘤患者的管理提出指导建议,该指南是对2012年指南的更新,新版指南涵盖了套细胞淋巴瘤的新的治疗观点,涉及移植数据,病理学进展尤其是分子病理学和PET/CT在肿瘤分期和治疗反应评估中的应用。

Blood:套细胞淋巴瘤

套细胞淋巴瘤(MCL)是一种罕见的非霍奇金淋巴瘤亚型,鉴于其预后不良,确诊时常采用化疗免疫联合疗法。现已发现其更多的惰性特点,如患者推迟初始治疗而不影响存活期。2016年世界卫生组织更新的分类描述了两种主要亚型,典型MCL和白血病性非淋巴结性MCL,各有其独特的分子特征和临床表现。目前尚无MCL的标准疗法,以利妥昔单抗和阿糖胞苷为主的强效化疗免疫方案,联合自体干细胞移植进行巩固、利妥昔单抗维持是年

中心点:来那度胺联合利妥昔单抗作为MCL的诱导和维持疗法可获得持久的MRD阴性的完全缓解。长期治疗相关的不良事件通常是非累积性的,且仍可控。摘要:研究人员开展了一多中心的2期试验,招募了38位未治疗过的MCL患者,中位年龄65岁,套细胞淋巴瘤国际预后指数(MIPI)评分分布在低、中、高风险(分别占34%、34%和32%),予以来那度胺联合利妥昔单抗(LR)作为初始治疗,包括诱导和维持。治疗持续至病
