The paper details research on treating highly lethal childhood cancer neuroblastoma. The study investigates combining the existing drug difluoromethylornithine (DFMO), which inhibits polyamine synthesis, with a proline- and arginine-free diet to enhance therapeutic outcomes. Researchers found that this combined approach drastically depleted the polyamine precursor ornithine, leading to a significant survival benefit and tumor differentiation in mouse models. Mechanistically, this depletion causes specific ribosome stalling at codons ending in adenosine, preferentially suppressing the…
