Isothiocyanates induce cancer cell apoptosis [11], cell cycle arrest [12], generation of reactive oxygen species (ROS) [12,13], regulate the activation of transcription factors STAT3, NFκB and Nrf2 [10,14,15], inhibit MAPK and PKC activities [12,16], down-regulate estrogen receptor [17] etc. However, the mechanism is not fully understood. Here, NFKB1 is linked to cancer.
