Cancer Research UK-funded scientists have revealed that a set of proteins act as the cell's 'nose' to 'sniff out' molecules which trigger cell growth, according to research published in Oncogene . Blocking these proteins stops cancer cell growth but seems to have less of an effect on healthy cells, as they may rely less on this family of proteins. Cancer Research UK scientists at the University of Oxford investigated the role in human cancer cells of a group of proteins - called Proton-Assisted Amino Acid Transporters (PATs). PATs carry amino acids through cell walls...
