Division of Cell and Molecular Biology

Much of the division’s research is concerned with genomic stability; in particular how cells normally ensure that no errors are made in copying the genome or repairing it after damage, and that a complete copy of the genome is inherited by each daughter cell. All of these processes can and do go wrong in cancer, and this leads to vulnerabilities in cancer cells that can be successfully exploited for treatment.

A second strength of the division is in studying protein function and interactions on a systems-wide scale to identify how signalling pathways are rewired in cancer cells, and how this affects cell behaviour, cell shape and cell metabolism.

Historically, scientists in the division were the first to make the ground-breaking discovery of the mechanism by which the RAS gene – one of the most commonly activated genes in cancer – causes cells to turn malignant through activation of the ERK-MAP kinase cell signalling pathway. 

Our research in cancer biology also helped identify and understand the BRAF oncogene, which is now an important drug target in malignant melanoma and other tumours.

The Division has oversight of and access to world-leading microscopy and proteomics facilities. The Centre for Genome Stability (CGS) at the ICR and The Royal Marsden, led by the Head of the Division of Cell and Molecular Biology, Professor Jonathon Pines, is a unique multidisciplinary programme bringing together scientific experts who work on DNA-damage response and genome instability research with clinical experts in the treatment of cancer.
