The project will commence in September 2023 and has funding from Cancer Research UK for 4 years. The student will be based in the Translational Cancer Metabolism lab (https://www.bartscancer.london/staff/dr-barrie-peck/) at the Barts Cancer Institute, Barts and the London Faculty of Medicine and Dentistry (FMD), Charterhouse Square in the City of London.
Aberrant metabolism is known to be central to oncogenic transformation. Indeed, some of the first treatments empirically identified to treat cancer target metabolic pathways. Although cancers undergo metabolic transformation to promote their growth, these changes can render tumours more sensitive than non-cancerous tissues to the targeting of their metabolic network. We have identified several nodes in Acetyl-CoA metabolism that impact the growth of cancer cells under the nutrient stress conditions found in the tumour microenvironment (Schug* & Peck* et al 2015 Cancer Cell)(Peck* & Schug* et al 2016 Cancer & Metabolism). More recently, we have uncovered novel tumour suppressors, such as CREBBP, whose loss promotes growth under nutrient stress conditions (Peck et al 2021 Cancer Research). To date, there are limited therapies that target Acetyl-CoA metabolism and those that do have substantial off-target effects. Thus, there is a need to identify novel tractable nodes in Acetyl-CoA metabolism in cancer. Our preliminary evidence suggests that CREBBP is a biomarker for fundamental metabolic rewiring resulting in increased Acetyl-CoA metabolism.
During this PhD we aim to:
1) Comprehensively elucidate the metabolic architecture of CREBBP-deplete cancer models.
2) Establish key regulators of Acetyl-CoA metabolism in CREBBP-deplete cancer cells.
3) Identify and validate novel metabolic inhibitors that have anti-cancer efficacy alone and in combination with first line therapy.
This work will significantly forward our knowledge of Acetyl-CoA metabolism in aggressive cancers. All the work in the Translational Cancer Metabolism lab has a direct line of sight to the clinic, working towards the ultimate goal of responsibly and reproducibly improving lives. Ultimately, this work will provide the rationale for testing these novel dependencies in patients with aggressive cancers.
The project would be suitable for a highly motivated candidate with a background in cell and molecular biology and an interest in using interdisciplinary approaches in cancer research. Previous experience of cancer metabolism and/or mammalian 3D models is not essential but would be advantageous.
