The latest news is that the enzyme CDK8 orchestrates cross-talk between two signalling pathways that are frequently deregulated in human cancers. There is no simple answer to the question of which cellular proteins or signalling pathways are responsible for making a cell cancerous. (...) Mutations in the gene for the retinoblastoma tumour-suppressor protein, which is part of another signalling pathway, are also frequently associated with cancer. When put together, the findings of Firestein et al. and Morris et al., presented in this issue, lead to the identification of a point at which these important pathways could communicate with each other in colorectal cancer.
