Overview
Research overview
Colorectal cancer (CRC) leads to approximately 600,000 deaths globally each year and is one of the major causes of death in the western world. In the UK it is the fourth most common cancer with around 40,000 new cases diagnosed each year (Cancer Research UK). At least half of these cases are thought to be preventable, as diet and lifestyle choices play a significant role in altering a person’s risk of developing cancer.
Perhaps unsurprisingly bowel cancer is strongly linked to dietary choices, for example a high fibre diet is associated with a lower cancer risk. However, the reasons for these links remain unknown. To gain a better understanding we need to study the intestinal stem cells that are responsible for maintaining a healthy bowel, as it is damage to these cells which can cause cancer.
However, in comparison to cancer there is little work performed on the normal bowel, partly due to the difficulty of obtaining samples from healthy people and lack of research teams capable of understanding the complete effect of diet on the bowel. The group is working to identify how the bacteria, immune system, epigenome and stem cells in the normal and cancerous bowel respond to different food types. The focus of the research is to improve our understanding of diet and health to provide accurate public advice and develop ways of preventing or detecting bowel cancer.
Biography
Originally from the South Wales valleys, my undergraduate training was completed in Cardiff University, followed by a PhD at the Institute of Medical Genetics at (what was then) the University of Wales College of Medicine. My Cancer Research Wales funded PhD was completed in the laboratory of Professors Julian Sampson and Jeremy Cheadle on the "Molecular and Functional Analysis of the Human Tumour Suppressor Genes TSC1 and TSC2". Upon completing my PhD in 2002 I took up a Postdoctoral Fellow position at the Murdoch Children's Research Institute (MCRI) in the Royal Children's Hospital in Melbourne, Australia. My work there was a change of focus from the cancer genetics of my PhD as I worked in the research groups of A/Prof Henrik Dahl and David Thorburn on Complex I deficiency in mitochondria. Upon completing this post I returned to Cardiff University and to cancer genetics, working on a Cancer Research UK funded project in the laboratory of Prof Alan Clarke. In July 2013 I took up a fellowship at the European Cancer Stem Cell Research Institute where my research focused on understanding and therapeutically exploiting the mechanisms that links the environment (diet & gut bacteria) to inflammation and colorectal cancer. In 2020 I became a lecture at Cardiff University's School of Biosciences, where I lead the Prevention and Early Detection of Cancer group.

Primary research
Colorectal cancer (CRC) is the 4th most frequent type of tumour and the 2nd leading cause of malignancy-related deaths in the Western world. Worldwide CRC incidence is increasing in female patients, those younger than 50 years-old and in low/middle income nations. As ~50% of CRC cases are preventable (WCRF-UK and Cancer Research UK websites) there is a potential to significantly reduce CRC incidence and address this global clinical need. Many of the fundamental mechanisms which link nutritional intake to physiological consequences remain undetermined. An improved mechanistic understanding would form part of a wider robust evidence base which is important in determining cause-and-effect relationships. There is a need to answer fundamental questions about the mechanisms by which diet impacts upon the normal biological processes and how they link through to influences on health and disease. Primary prevention can be achieved with greater understanding of how the major CRC risk factors of diet and lifestyle impact on the intestinal stem cell from which CRC originates. Secondary prevention can be achieved with improvements in existing and new techniques for the early detection of the pre-malignant polyps prior to thier progression to carcinoma.
It is well documented that CRCs evolve through loops of deregulated inflammatory stimuli which are sustained by DNA damage signalling pathways and epigenetic re-modelling (DNA methylation). Intensive work in recent years has led to the identification of genes and mechanisms that link diet to changes in the gut microbiota, and the pigenome. These alterations drive epithelial and inflammatory/immune responses which interact with intestinal stem cell and can increase or decrease CRC risk. As a lab we aim to foster symbiotic relationships with a multidisciplinary team that includes epidemiologists, dietitians, exercise physiologists, translational scientists, basic scientists, clinical researchers, clinicians, statisticians and public health professionals, all of whom bring their individual specialties to the common purpose. As we believe that synergic analysis of all parameters could provide new biological insights and effective biomarkers that could have applications in prevention, molecular diagnosis, prognosis and treatment of intestinal disease and CRC.
