Extrinsic and intrinsic effect of inflammatory-driven Notch activation on tumorigenesis. When Notch signaling is activated in macrophages, it can induce the production of specific inflammatory mediators which in turn stimulate epithelial cells: thus, although not occurring into the epithelial cell, the dysregulation of the Notch pathway can indirectly exert a control on tumor progression (extrinsic effect). Alternately, the inflammatory milieu can directly modulate the Notch signaling within the epithelial cells, regulating several molecular processes involved in tumorigenesis (intrinsic effect)
