reach
"In addition, the inducible expression of a mutant 4E-BP1 protein that can not be phosphorylated by mTOR blocked protein synthesis and inhibited the growth of Ewing sarcoma cells in vitro and in vivo in a xenograft."

reach
"We also engineered a mutant 4E-BP1 that can not be phosphorylated by mTOR resembling de-phospho-Thr46-4E-BP1, and generated HNSCC cells expressing this mutant in a tetracycline inducible fashion."

reach
"MTORi treatment or conditional expression of a mutant 4E-BP1 that can not be phosphorylated by mTOR was sufficient to disrupt the translation initiation complex and prevent tumor growth."
