Nuclear factor-kappaB and tumor-associated macrophages.
Tumor-associated macrophages (TAM) have been linked with the progression of cancer by favoring tumor angiogenesis, growth, and metastasis. The precise mechanisms that maintain the protumor phenotype of TAM are poorly understood, but recent research has highlighted a number of signaling pathways that are important in TAM phenotype and function. Nuclear factor-kappaB (NF-kappaB) is considered the master regulator of inflammatory and immune responses. Recently several genetic studies have indicated NF-kappaB is an important pathway in TAM for the integration of signals from the tumor microenvironment that promote carcinogenesis. This review will focus on the role of NF-kappaB in TAM and the potential of targeting this pathway as a novel therapeutic strategy against cancer.
