mTORC1 Activates SREBP-1c and Uncouples Lipogenesis From Gluconeogenesis Please share
... both insulin resistance and SREBP-1c cleavage and activation (21). Together, these findings suggest that, in obese/insulinresistant models, overactivation of mTORC1 by amino acids could (i) further reduce insulin signaling through the degradation of IRS, (ii) promote FoxO1-mediated induction of the g ...
