It is an important cell signaling hub highly phosphorylated upon integrin activation, and has long been recognized as promoting cancer cell migration, proliferation, and survival/chemoresistance through downstream activation of Rho-GEF, talin, cortactin, SFKs, PI3K/AKT, Ras/MAPK, or NF-κB pathways (303, 304) (Figure 1). Here, NFKB1 is linked to cancer.
