Developing models to test new drug treatments for childhood leukaemia

What difference will this project make?

In this new project Dr Williams and his colleagues are focusing on a cell signalling pathway in the body called STAT3. They have already proved that leukaemic cells in a common type of the disease depend on this pathway for their survival.

Together with other scientists, they have shown that other childhood leukaemias are also dependent on this pathway, and that cancerous cells can be eliminated by drugs that block it.

The team now plans to see whether blocking the pathway has therapeutic potential, and to understand how it is controlled in leukaemia. This knowledge will be used to identify existing drugs that are currently used for other diseases which could then serve as new therapies.

They will focus their efforts on leukaemias that are difficult to treat using current chemotherapy, and identify compounds that can eliminate leukaemia cells by inhibiting the pathway, while at the same time having minimal side-effects.

Drugs that have already been approved for clinical use will be candidates for fast-track use in this ground-breaking therapy. Ultimately this will improve the treatment options for children with leukaemia, especially those with types of the disease that can be difficult to treat.
