Therefore, Numb controls both an oncogenic pathway (the Numb: Notch axis) and a tumour suppressor pathway (the Numb: p53 axis).

The adenomatous polyposis coli (APC) gene is a tumour suppressor gene, i.e. a gene preventing uncontrolled cell growth that could lead to the formation of a cancer tumour.

BRCA2 tumour suppressor protein has a recognized role in the repair of DNA double strand breaks by homologous recombination.

For example, whereas the p53 / p63 / p73 tumour suppressor family is holozoan - specific31, the HIPK kinase that phosphorylates p53 in the presence of DNA breaks is metazoan - specific, and the MDM2 ubiquitin ligase that regulates p53 appears as a eumetazoan feature.

The task is large but not insurmountable, says Rebecca: «One of the big problems with this cancer is that it doesn't have a recurrent driver gene — it's a disease dominated much more by multiple tumour suppressor genes being lost.

BRCA1 is a tumour suppressor gene involved in DNA repair through homologous recombination and in preserving the integrity of the genome.

«Over 40 % of prostate cancers lose PTEN and some lose both PTEN and another tumour suppressor gene, INPP4B, but we didn't previously have a clear picture of how this affects tumour growth,» says IMED Biotech Unit scientist Sabina Cosulich, at AstraZeneca.

PTEN is known as a tumour suppressor gene meaning that it typically slows the growth of cells and its loss can lead to cancer.

Our work suggests that studying PI (3,4) P2 - regulated processes may reveal why PTEN is such a powerful tumour suppressor and may also help us to identify new therapeutic targets in PTEN - mutated cancers.»

A recurring theme is the overlap of these core «multicellularity» genes with genes perturbed in cancer, a disease of aberrant multicellularity (see oncogenes and tumour suppressors in Figs 2 and 3).

Non-functional tumour suppressors or activated oncogenes can cause the development of cancer.
