| Research Abstract |
In this study, we examined the crosstalk between stress and inflammatory cytokine signaling in metabolic syndrome using adipocytes, hepatocytes and pancreatic beta cells, especially focused on contribution of the members of pseudokinase family TRBs, which are induced by various stresses.
Both signals were strongly attenuated the maturation and function of adipocytes(3T3-L1 cells and HW11 cells). On the other hand, in human hepatoma cell line, HepG2 cells, stress induced TRB3 potently inhibited the signaling of one of the inflammatory cytokines, TGFβ. Moreover the impairment ofβcell line, Min6 cells, induced by endoplasmic reticulum stress is rescued by TGFβ. Our findings suggest that the crosstalk of both signal showed the cell-specific phenotype, and that TRBs proteins function as the tuner of these responses.
