Trosolwg ymchwil

Mae canser y colon yn arwain at oddeutu 600,000 o farwolaethau yn fyd-eang bob blwyddyn ac mae'n un o brif achosion marwolaeth yn y byd gorllewinol. Dyma'r pedwerydd canser mwyaf cyffredin yn y DU, gyda thua 40,000 o achosion newydd yn cael eu diagnosio bob blwyddyn (Cancer Research UK). Credir bod modd atal o leiaf hanner yr achosion hyn, gan fod dewisiadau ar gyfer diet a ffordd o fyw yn chwarae rhan sylweddol wrth newid risg person o ddatblygu canser.

Efallai nad yw'n syndod bod cysylltiad cryf rhwng canser y coluddyn â dewisiadau dietegol, er enghraifft mae deiet ffeibr uchel yn gysylltiedig â risg is o ganser. Fodd bynnag, nid yw'r rhesymau dros y cysylltiadau hyn yn hysbys o hyd. Er mwyn cael gwell dealltwriaeth mae angen i ni astudio'r bôn-gelloedd perfeddol sy'n gyfrifol am gynnal coluddyn iach, gan mai niwed i'r celloedd hyn sy'n gallu achosi canser.

Fodd bynnag, o gymharu â chanser, ychydig iawn o waith a wneir ar y coluddyn arferol, yn rhannol oherwydd anhawster cael samplau gan bobl iach a diffyg timau ymchwil sy'n gallu deall effaith gyflawn deiet ar y coluddyn. Mae'r grŵp yn gweithio i nodi sut mae'r bacteria, y system imiwnedd, epigenom a'r bôn-gelloedd yn y coluddyn arferol a chanseraidd yn ymateb i wahanol fathau o fwyd. Ffocws yr ymchwil yw gwella ein dealltwriaeth o ddeiet ac iechyd i ddarparu cyngor cyhoeddus cywir a datblygu ffyrdd o atal neu ganfod canser y coluddyn.

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.

Current projects:

  • Molecular and Functional Characterization of the Role of Foxp3+ Regulatory T (Treg) Cells in the Development of Intestinal Cancer
  • Molecular and Functional Characterisation of the Nutri-Epigenetic Effects of Chemopreventative Polyphenols in Intestinal Cancer
  • Identifying the influence of the microbiome and metabolome on the normal and
    malignant murine intestinal stem cell
  • Exploiting oncotropic bacteria for early detection of colorectal cancer

Bywgraffiad

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.
