摘要

Multiple genetic alterations pave the way for transformation of a normal cell into a cancer cell. At the core of this process are oncogenic (cancer-causing) mutations in critical genes, which lead to sustained proliferative drive and desensitization of the cell to cues that normally inhibit growth or promote cell death. Almost exactly 25 years ago, two landmark papers published in Nature showed that a single onco-gene is insufficient to make normal cells cancerous, whereas cooperation between two distinct oncogenic mutations can do the job. Writing on page 1112 of this issue, some of the same authors now delve deeper into the genetics of oncogene cooperation and uncover many genes whose altered expression is important for malignancy. Intriguingly, in many cases 'normalizing' the expression of even one of these genes is sufficient to attenuate tumour growth.
