Efficacy of RNA polymerase II inhibitors in targeting dormant leukaemia cells (2013)
Journal Article

Background Dormant cells are characterised by low RNA synthesis. In contrast, cancer cells can be addicted to high RNA synthesis, including synthesis of survival molecules.

Journal Article

Background Aurora kinases play an essential role in orchestrating chromosome alignment, segregation and cytokinesis during mitotic progression, with both aurora-A and B frequently over-expressed in a variety of human malignancies. Over-expression of... Read More about P-glycoprotein and breast cancer resistance protein in acute myeloid leukaemia cells treated with the Aurora-B Kinase Inhibitor barasertib-hQPA.

Analysis of factors that affect in vitro chemosensitivity of leukaemic stem and progenitor cells to gemtuzumab ozogamicin (Mylotarg) in acute myeloid leukaemia (2009)
Journal Article

Relapse in acute myeloid leukaemia (AML) is considered to result from the persistence of drug-resistant leukaemic stem and progenitor cells (LSPC) within a bone marrow ‘niche’ microenvironment. Identifying novel agents that have the potential to targ...

Resistance to FLT3 inhibition in an in vitro model of primary AML cells with a stem cell phenotype in a defined microenvironment (2008)
Journal Article

Relapse in acute myeloid leukaemia (AML) is mediated by survival of leukaemic stem cells following remission-induction chemotherapy. It would therefore be useful to identify therapeutic agents that target leukaemic stem cells. We devised a flow cytom...

P-glycoprotein is downregulated in KG1a-primitive leukemia cells by LDL cholesterol deprivation and by HMG-CoA reductase inhibitors (2007)
Journal Article

Objective P-glycoprotein (pgp) is a membrane transporter encoded by the multidrug resistance (MDR1, ABCB1) gene. Pgp is a poor prognostic factor in elderly patients with acute myeloid leukemia (AML). In addition to its role in drug efflux, pgp has b...

Advances in the understanding of susceptibility to treatment-related acute myeloid leukaemia (2004)
Journal Article

Treatment-related acute myeloid leukaemia (t-AML) is a devastating complication following exposure to the cytotoxic and genotoxic agents used to treat a primary malignancy.

Clonal haemopoiesis may occur after conventional chemotherapy and is associated with accelerated telomere shortening and defects in the NQO1 pathway; possible mechanisms leading to an increased risk of t-AML/MDS (2004)
Journal Article

The molecular pathogenesis of therapy-related acute myeloid leukaemia/myelodysplastic syndrome (t-AML/MDS) remains uncertain.
