Amino acids have a dual role in cellular metabolism, as they are both the
building blocks for protein synthesis and intermediate metabolites which fuel
other biosynthetic reactions. Recent work has demonstrated that deregulation of
both arms of amino acid management are common alterations seen in cancer. Among
the most highly consumed nutrients by cancer cells are the amino acids glutamine
and serine, and the biosynthetic pathways that metabolize them are required in
various cancer subtypes and the object of current efforts to target cancer
metabolism. Also altered in cancer are components of the machinery which sense
amino acid sufficiency, nucleated by the mechanistic target of rapamycin (mTOR),
a key regulator of cell growth via modulation of key processes including protein
synthesis and autophagy. The precise ways in which altered amino acid management
supports cellular transformation remain mostly elusive, and a fuller mechanistic
understanding of these processes will be important for efforts to exploit such
alterations for cancer therapy.
