| Outline of Final Research Achievements |
In this study, we searched for insulin signal-activating component from spices and evaluated its anti-diabetic effects. We demonstrated that isothiocyanates found in cruciferous vegetables potently inhibits protein tyrosine phosphatase 1B (PTP1B), which negatively regulates insulin signaling. Moreover, we found that phenethyl isothiocyanate induces the ligand-independent activation of insulin signaling by inhibiting cellular PTP1B and increases glucose uptake in mouse C2C12 myotubes.
