Snail determines the therapeutic response to mTOR kinase inhibitors by transcriptional repression of 4E-BP1

Abstract

4E-BP1 is a translational repressor critical in mTOR signaling, whereas Snail is a critical promoter of epithelial to mesenchymal transition. Here the authors show that Snail induces resistance to mTOR inhibitors by repressing 4E-BP1 expression and promoting cell cycle progression via upregulating cycD.
