Tumorigenesis: Combined effort

Gemma K. Alderton

Probably only a few mutations drive tumour development and progression, but identifying these and defining a therapeutic route through which to exploit them is not easy. Based on their previous findings that cooperating oncogenic mutations lead to synergistic changes in downstream signalling pathways, Hartmut Land and colleagues have shown that a significant number of such synergistic changes are crucial for tumorigenesis.
