Study details genes that control whether tumors adapt or die when faced with p53 activating drugs

When turned on, the gene p53 turns off cancer. However, when existing drugs boost p53, only a few tumors die -- the rest resist the challenge. A new study shows how: tumors that live even in the face of p53 reactivation create more of the protein p21 than the protein PUMA; tumors that die have more PUMA than p21. And, for the first time, the current study shows a handful of genes that control this ratio.
