The mammalian target of rapamycin, mTOR, plays key roles in cell growth and
proliferation, acting at the catalytic subunit of two protein kinase complexes:
mTOR complexes 1 and 2 (mTORC1/2). mTORC1 signaling is switched on by several
oncogenic signaling pathways and is accordingly hyperactive in the majority of
cancers. Inhibiting mTORC1 signaling has therefore attracted great attention as
an anti-cancer therapy. However, progress in using inhibitors of mTOR signaling
as therapeutic agents in oncology has been limited by a number of factors,
including the fact that the classic mTOR inhibitor, rapamycin, inhibits only some
of the effects of mTOR; the existence of several feedback loops; and the crucial
importance of mTOR in normal physiology.
