The INK4a/ARF network in tumour suppression

Nat Rev Mol Cell Biol. 2001 Oct;2(10):731-7. doi: 10.1038/35096061.

Abstract

The retinoblastoma protein (RB) and p53 transcription factor are regulated by two distinct proteins that are encoded by the INK4a/ARF locus. Genes encoding these four tumour suppressors are disabled, either in whole or in part, in most human cancers. A complex signalling network that interconnects the activities of RB and p53 monitors oncogenic stimuli to provide a cell-autonomous mode of tumour surveillance.
