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 study published in the journal Cell Reports shows how: tumors that live even i ...
