Abstract

The phosphatidylinositide-3-kinase(PI3K)/ protein kinase B(Akt)/ mammalian target of rapamycin(mTOR)pathway is recognized to have an important role in the development and progression of colo-rectal cancer(CRC). The most extensively characterized downstream targets of mTORC1 are ribosomal protein S6 kinase 1(p70S6K1)and eukaryotic translation initiation factor(eIF)4E-binding protein 1(4EBP1),both of which are crucial to the regulation of protein synthesis. The abnormal expression of p70S6K1 and 4EBP1 in CRC has become the focus of attention.
