Background and Research Focus

Chris is a Senior Lecturer in the Institute of Cancer and Genomic Sciences with a long-standing interest in gastrointestinal disease. Chris’s group in collaboration with Prof Tariq Iqbal (Consultant Gastroenterologists UHB) focuses specifically on the role of iron and the intestinal microbiome in intestinal disease.  His group has demonstrated that deregulation of proteins involved in iron metabolism are crucial to the development of several different cancers including oesophageal and colorectal cancer. These changes are associated with a modulation in a number of molecular pathways and most recently we have described the importance of various predisposing mutations in determining the impact of iron on tumourigenesis.  Current research involves utilizing iron chelators as a mechanism of inhibiting free reactive iron in the gut and thus a platform for therapeutic intervention. Iron also impacts on the intestinal microbiota and thus our research group is focusing on identifying how iron modulates the microbiome and how iron chelators might impact on this. Finally, in the context of inflammatory bowel disease we are also interested in determining the efficacy of faecal transplantation in the management of these patients and specifically defining the bacterial strains which are associated with a clinical improvement. Once defined the group will begin to encapsulate these strains into unique formulations which will alleviate the need for faecal transplants.

 

Expertise

Cancer Cell Biology; gastrointestinal cancer; inflammatory bowel disease, iron chelation

 

Other activities

Chris has forged strong collaborations with both experts in the Schools of Chemistry and Chemical Engineering at the University of Birmingham and from Industry to further develop iron chelation technologies. This has led to the discovery of highly promising dietary iron chelators to treat cancer and culminated in several pending patents. Chris has published in excess of 60 research articles in the field of cancer and iron metabolism. He has received funding from the Cancer Research UK, BBSRC, WCRF, CORE and the UHB Charities. Alongside his research, Chris has made substantial contributions to teaching both undergraduate and post graduate students. Most pertinently he currently serves as Programme Director for the undergraduate Biomedical Science programme. He is also module lead on the ‘Digestive system’ module which is delivered as a core MBChB module to all 400 first year medical students. Finally, he contributes to a host of Cancer Research UK/University of Birmingham outreach activities.
