Outline of Final Research Achievements |
We showed that DGKζ regulates insulin-induced GLUT4 translocation to PM in a canonical insulin-signal independent manner. In addition, DGKζ-associated protein, PIP5K1α modulates GLUT4 translocation in a similar mechanism as DGKζ. By using ELISA kit, we succeeded to identify around 30 small compounds which inhibit the interaction between IRS-1 and DGKζ. Addition of one of these compounds, Compound A, inhibited the interaction between IRS-1 and DGKζ in HEK293T cells. Moreover Compound A addition recovered TNF-α-induced insulin resistance in 3T3-L1 adipocytes.
