Introduction: Sulforaphane (SFN), a naturally occurring isothiocyanate present in cruciferous vegetables, is an attractive agent due to its potent anticancer effects. SFN was shown to suppress the proliferation of various cancer cells in vitro and in vivo, whereas the underlying molecular mechanisms remain largely unknown. Previous studies could demonstrate that modulation of polyamine metabolism provides a chemopreventive strategy of different phytochemicals. Thus, the objective of this study was to elucidate a possible regulation of ornithine decarboxylase (ODC), the key enzyme of polyamine biosynthesis, by SF…
