Tumour suppressors: Spread your wings

Gemma K. Alderton

The Drosophila melanogaster Salvador (SAV)–Warts (WTS)–Hippo (HPO) pathway is a conserved tumour suppressor pathway that functions to regulate cell growth and apoptosis through inhibition of the downstream transcriptional co-activator Yorkie (YKI), the key targets of which include cyclin E, the microRNA bantam and Drosophila inhibitor of apoptosis 1 (diap-1, also known as th). Alain Zider and colleagues have now uncovered an additional oncogenic target of this pathway: the E2F1 transcription factor.
