摘要: 目的: 探讨NFκB在维持口腔癌相关巨噬细胞炎症细胞募集表型中的作用。方法: 使用Cal27条件培养基刺激诱导小鼠原代巨噬细胞,形成口腔癌相关巨噬细胞,利用NFκB小分子抑制剂Bay11-7082抑制NFκB信号通路。利用RT-PCR、ELISA检测募集炎症细胞相关趋化因子的表达及分泌变化。采用GraphPadPrism5对数据进行统计学分析。结果: Bay11-7082处理的巨噬细胞能够抑制Cal27条件培养基诱导原代巨噬细胞形成肿瘤相关巨噬细胞的梭状外形;同时,在mRNA水平抑制炎症细胞募集相关趋化因子MCP-1、GM-CSF、MCP-5以及CCL-5的表达上调(P<0.05)。在蛋白质水平,对NFκB的抑制能够显著减少Cal27条件培养基导致的巨噬细胞MCP-1、GM-CSF分泌增加(P<0.001)。结论: NFκB信号通路可能参与口腔癌相关巨噬细胞募集炎症细胞表型的维持。

Abstract: PURPOSES: To explore the ability of nuclear factor κB (NFκB) in sustaining inflammatory cell recruitment phenotype of oral cancer associated macrophages, by using NFκB inhibitor(-Bay11-7082). METHODS: By primary culture, murine macrophages were harvested. Cal27 conditioned medium (CM) and Bay11-7082 were applied for stimulation of the macrophages. RT-PCR and ELISA were used for detecting the inflammatory cell recruitment related chemotactic factors. GraphPadPrism5 was used for statistical analysis. RESULTS: Bay11-7082 prevented the contour change into a spindle shape via Cal 27 CM. It also attenuated MCP-1, GM-CSF, MCP-5 and CCL-5 mRNA increase after Cal 27 CM stimulation (P<0.05). At protein level, impeding NFκB activation could significantly prevent MCP-1 and GM-CSF secretion from oral cancer associated macrophage (P<0.001). CONCLUSIONS: NFκB signaling may play a key role in sustaining the inflammatory cell recruitment phenotype of oral cancer associated macrophages.
