Myelodysplasia (MDS) is a common blood cancer that predominantly occurs in people over 60 years of age. It causes symptoms through low blood counts, leading to infection, bleeding or blood transfusion. MDS can turn into acute leukaemia (AML) and this is caused by the acquisition of new changes in the DNA. Azacitidine is the only PBS funded medication to treat MDS, but the underlying mechanisms of response are still poorly understood.
Prof Lane’s group has generated a model of MDS that turns into AML and is using sophisticated methods to understand how normal stem cells turn into leukaemia. Their preliminary experiments have identified a protein called CDX-2 is over-expressed in leukaemia and high risk MDS. Using this model, they have demonstrated that azacytidine specifically targets the leukaemia cells to increase cell death. This proposal will better understand this azacytidine response, and build on it by combining azacytidine with a new drug, venetoclax with the aim to improve outcomes in MDS and AML.
