This study aimed to explore the therapeutic effects of autologous peripheral blood stem cell transplantation (APBSCT) with Jiedu Xiaoluo decoction (JDX) on non-Hodgkin lymphoma (NHL).
B lymphoma cells A20 were used to establish nude mice-transplanted tumor model. The peripheral blood of mice was analyzed by automatic blood cell counter. Inflammatory cytokines in tumor tissues were measured by ELISA, real-time qRT-PCR, and western blotting assays. Immunohistochemical staining was employed to evaluate tumor cell growth and apoptosis. CCK8 and Transwell assays were used to detect cell viability, migration, and invasion. Cell apoptosis in vitro was evaluated with flow cytometry.
In the in vitro co-culture system of A20 cells and hemopoietic stem cells (HSC), JDX notably inhibited the proliferation, migration, and invasion and promoted apoptosis of A20 cells compared to HSC treatment alone. In animal tumor xenografts of NHL, the combination of APBSCT with JDX significantly promoted hematopoietic reconstitution, inhibited tumorigenesis of A20 cell, promoted the inflammatory microenvironment remission, inhibited cell proliferation, and promoted apoptosis compared to APBSCT alone.
The combination of APBSCT with JDX might be an effective strategy to treat NHL through inhibiting tumorigenesis and reconstructing hematopoietic and immune microenvironment. Our finding provided a novel insight into the clinical application of Traditional Chinese Medicine (TCM) against NHL.
本研究旨在探讨自体外周血干细胞移植(APBSCT)联合解毒消瘤汤(JDX)治疗非霍奇金淋巴瘤(NHL)的疗效。
采用B淋巴瘤细胞A20建立裸鼠移植瘤模型。用自动血细胞计数器分析小鼠外周血。通过酶联免疫吸附测定(ELISA)、实时定量逆转录-聚合酶链反应(qRT-PCR)和蛋白质免疫印迹法检测肿瘤组织中的炎性细胞因子。采用免疫组织化学染色评估肿瘤细胞的生长和凋亡。使用细胞计数试剂盒-8(CCK8)和Transwell实验检测细胞活力、迁移和侵袭能力。通过流式细胞术评估体外细胞凋亡情况。
在A20细胞与造血干细胞(HSC)的体外共培养体系中,与单独的HSC处理相比,JDX显著抑制了A20细胞的增殖、迁移和侵袭,并促进了其凋亡。在NHL动物肿瘤异种移植模型中,与单独的APBSCT相比,APBSCT联合JDX显著促进了造血重建,抑制了A20细胞的肿瘤发生,促进了炎性微环境的缓解,抑制了细胞增殖,并促进了细胞凋亡。
APBSCT联合JDX可能是一种通过抑制肿瘤发生以及重建造血和免疫微环境来治疗NHL的有效策略。我们的研究结果为中药治疗NHL的临床应用提供了新的见解。
