肿瘤相关巨噬细胞(TAMs)在肿瘤进展中的关键作用现已得到证实。TAMs已被证明影响肿瘤发展的多个步骤,包括肿瘤细胞的生长、存活、侵袭和转移,以及肿瘤的血管生成和淋巴管生成。将TAMs极化成这样一种前列腺癌表型的分子回路现在是密集研究的焦点。转录因子核因子-κB(核因子-κB)是许多细胞过程的主要调节因子,并被证明调节影响TAMs功能的各种途径。这一点的许多证据来自于使用优雅的转基因小鼠肿瘤模型,在该模型中,已经证明通过修改NF-κB信号通路的单一成分来调节TAMs的亲肿瘤谱系。在这里,我们概述这一证据,并试图调和最近出现的关于NF-κB在这一现象中的确切作用的不同观点。
The pivotal role of tumor-associated macrophages (TAMs) in tumor progression is now well established. TAMs have been shown to influence multiple steps in tumor development including the growth, survival, invasion, and metastasis of tumor cells as well as angiogenesis and lymphangiogenesis in tumors. The molecular circuits that polarize TAMs toward such a protumoral phenotype are now the focus of intense investigation. The transcription factor, nuclear factor–κB (NF-κB), is a master regulator of many cellular processes and been shown to regulate various pathways that impact on the function of TAMs. Much evidence for this has come from the use of elegant transgenic murine tumor models in which modification of single components of the NF-κB signaling pathway has been shown to regulate the pro-tumor repertoire of TAMs. Here, we outline this evidence and attempt to reconcile the various views that have emerged recently over the exact role of NF-κB in this phenomenon.
