This study shows that Myc-driven tumourigenesis is dependent on its ability to increase protein synthesis, as haploinsufficiency in ribosomal proteins decreases Myc-induced tumour formation. However, tumours caused by the loss of p53, were not affected. Myc stimulates cap-dependent protein translation at the expense of IRES-dependent translation, leading to the synthesis of a different set of proteins, and this effect is reversed by ribosomal protein haploinsufficiency.
