Some p53 mutations result in gain-of-function variants that can contribute to tumorigenesis. Three such mutants, R175H, R273H and R280K p53, are now shown to cooperate with transcription factor E2F1 to upregulate the expression of ID4, which in turn stabilizes the transcripts from pro-angiogenic factors IL-8 and GRO-α.
