摘要:
6-(Methylsulfinyl)hexyl isothiocyanate (6-MSITC) is a bioactive ingredient present in wasabi, a popular pungent spice in Japan. Previous studies have revealed the cytoprotective and cancer chemopreventive effects of 6-MSITC. This study aims to clarify the molecular mechanisms by investigating the action of 6-MSITC on the Nrf2/Keap1 system. 6-MSITC up-regulated the expression of NAD(P)H:quinone oxidoreductase 1 (NQO1) by increasing the Nrf2 level. Treatment with 6-MSITC extended the half-life (t1/2) of Nrf2 protein from 11.5 to 35.2 min, approximately three times longer. Moreover, 6-MSITC suppr...
