We have demonstrated that T3 increases the expression of ZAKI-4alpha, an endogenous calcineurin inhibitor. In this study we characterized a T3-dependent signaling cascade leading to ZAKI-4alpha expression in human skin fibroblasts. We found that T3-dependent increase in ZAKI-4alpha was greatly attenuated by rapamycin, a specific inhibitor of a protein kinase, mammalian target of rapamycin (mTOR), suggesting the requirement of mTOR activation by T3. Indeed, T3 activated mTOR rapidly through… CONTINUE READING
