title: NF-κB as a central regulator of macrophage function in tumors.
abstract: TAMs are usually abundant in the tumor microenvironment and are now known to play an essential role in tumor progression. For example, TAMs influence many aspects of tumorigenesis, such as the growth, survival, invasion, and metastasis of tumor cells, tumor angiogenesis, and the suppression of other tumor-infiltrating immune effector cells. The molecular pathways that regulate these tumor-promoting functions of TAMs are currently under intense investigation. Several recent studies about transgenic murine tumor models have shown that the transcription factor NF-κB is a key player in tumor progression with distinct roles in regulating the functions of macrophages and tumor cells in malignant tumors. Here, we outline the evidence for classical and noncanonical NF-κB signaling pathways driving the tumor-promoting repertoire of TAMs.
