The anti-malarial drug atovaquone potentiates platinum-mediated cancer cell death by increasing oxidative stress.

James T T Coates, Gonzalo Rodriguez-Berriguete, Rathi Puliyadi, Thomas Ashton, Remko Prevo, Archie Wing, Giovanna Granata, Giacomo Pirovano, Gillies W McKenna, Geoff S Higgins,

Platinum chemotherapies are highly effective cytotoxic agents but often induce resistance when used as monotherapies. Combinatorial strategies limit this risk and provide effective treatment options for many cancers. Here, we repurpose atovaquone (ATQ), a well-tolerated & FDA-approved anti-malarial agent by demonstrating that it potentiates cancer cell death of a subset ... Read more >>

Katharine J Herbert, Rathi Puliyadi, Remko Prevo, Gonzalo Rodriguez-Berriguete, Anderson Ryan, Kristijan Ramadan, Geoff S Higgins,

T-LAK-originated protein kinase (TOPK) overexpression is a feature of multiple cancers, yet is absent from most phenotypically normal tissues. As such, TOPK expression profiling and the development of TOPK-targeting pharmaceutical agents have raised hopes for its future potential in the development of targeted therapeutics. Results presented in this paper confirm ... Read more >>

4D-PET reconstruction using a spline-residue model with spatial and temporal roughness penalties.

George P Ralli, Michael A Chappell, Daniel R McGowan, Ricky A Sharma, Geoff S Higgins, John D Fenwick,

4D reconstruction of dynamic positron emission tomography (dPET) data can improve the signal-to-noise ratio in reconstructed image sequences by fitting smooth temporal functions to the voxel time-activity-curves (TACs) during the reconstruction, though the optimal choice of function remains an open question. We propose a spline-residue model, which describes TACs as ... Read more >>

Remko Prevo, Giacomo Pirovano, Rathi Puliyadi, Katharine J Herbert, Gonzalo Rodriguez-Berriguete, Alice O'Docherty, William Greaves, W Gillies McKenna, Geoff S Higgins,

Cyclin-dependent kinase 1 (CDK1) orchestrates the transition from the G2 phase into mitosis and as cancer cells often display enhanced CDK1 activity, it has been proposed as a tumor specific anti-cancer target. Here we show that the effects of CDK1 inhibition are not restricted to tumor cells but can also ... Read more >>

Oxidative Phosphorylation as an Emerging Target in Cancer Therapy.

Thomas M Ashton, W Gillies McKenna, Leoni A Kunz-Schughart, Geoff S Higgins,

Cancer cells have upregulated glycolysis compared with normal cells, which has led many to the assumption that oxidative phosphorylation (OXPHOS) is downregulated in all cancers. However, recent studies have shown that OXPHOS can be also upregulated in certain cancers, including leukemias, lymphomas, pancreatic ductal adenocarcinoma, high OXPHOS subtype melanoma, and ...

Targeting tumour hypoxia: shifting focus from oxygen supply to demand.

James T Coates, Michael Skwarski, Geoff S Higgins,

Tumour hypoxia is a well-recognised barrier to anti-cancer therapy and represents one of the best validated targets in oncology. Previous attempts to tackle hypoxia have focussed primarily on increasing tumour oxygen supply; however, clinical studies using this approach have yielded only modest clinical benefit, with often significant toxicity and practical ...
