I joined the University of Sheffield as a lecturer in 2002 following training in molecular pharmacology.

My research training was in microbial molecular biology and my first postdoc was in Sheffield with Professor Anne Moir in the Department of Molecular Biology and Biotechnology. I subsequently worked with Professor Caroline Dive in Manchester, studying the regulation of apoptosis in response to chemotherapeutic drugs. It was through this research that I became interested in the regulation of apoptosis by butyrate.

Research Interests

Work in my group examines the relationship between diet, short-chain fatty acid production and metabolism and cell fate in the normal and neoplastic colon. A detailed summary is found on my Research Page.

Butyrate and cell fate determination: Butyrate is of particular interest as it is described as an inhibitor of histone deacetylases – although we disagree with this (Corfe, 2012), is in clinical trials or clinical use, yet it is also a fermentation product of the gut microbiome present at pharmacologically active concentrations in the normal healthy colon lumen. It has been implicated as a mechanism for cancer prevention by fibre. HDACs do not solely deacetylate histones and a growing literature recognises protein acetylation as a regulatory mechanism comparable with phosphorylation. My group studies the transcription factor Sp1 (Chirakkal et al., 2006; Waby et al., 2010, Yu et al., 2010) and the cytoskeletal proteins keratin 8, 18 and 19 (Leech et al., 2008; Drake et al., 2009; Khan et al., 2011; Majumdar et al., 2012) all of whose functions are controlled, inter alia, by acetylation.

Short-chain fatty acid metabolism: We are currently working on the relationship between production of acetyl-coA (the substrate for protein acetylation) and acetylation of metabolic enzymes involved in its production. Differences between the management and effects of SCFA are a particular interest (Kilner et al., 2012; Astbury & Corfe 2012)). We use a combination of systems biology and protemics for this work.

Crypt cell fate modelling: We have noted changes in the composition of cell types in the colon crypt in response to butyrate and to neoplasia (Yu et al., 2011) and we are developing fully semantic models to examine crypt cell fate determination (Smallbone and Corfe, submitted).

Organ level modelling: I am increasingly interested in the concept of field cancerization as applied to the colon and an ongoing study using proteomic approaches is revealing multiple proteins and pathways that are altered in the normal tissues around fields (Corfe et al., 2009) has led us to propose testable qualitative models to axamine mechanisms of field cancerization (Rosser et al, submitted). Modelling approaches are being trialled in collaboration with Professor Steve Billings, Yifan Zhao and Hualiang Wang (ACSE) and Kieran Smallbone (MCISB).

Diet-Microbiome Interactions, Functional analysis of Probiotics: I am sceptical about the centrality of fibre as a determinant of SCFA concentrations (Williams et al., submitted). We have initiated a programme of studies to generate a complete detailed description of the diet, microbiome and luminal metabolome in steady state and in response to probiotics. This is done in collaboration with Julian Marchesi (Cardiff), Sue Plummer and Iveta Garaiova (Obsidian Ltd). We are using a non-linear approach to assess which factors are important and which factors interact in the production of SCFA, in collaboration with Professor Stephen Billings (Automated Control and Systems Engineering).

Interface with Humanities: Gastrointestinal conditions often get reported late or at an advanced state due to stigmatisation of GI functions by society. Irritable Bowel Syndrome in particular is an often-debilitating . We are collaborating with Vicky Grant and Brendan Stone (English) to develop narratives around IBS. We have explored social media and its conflict with peer-reviewed literature within a framework of discourse theory (Sprake et al., 2012). We are interested in the philosophy of systems biology and the scientists relationship with hypothesis rejection (Evans & Corfe, submitted; Corfe, 2012; Blog: scientist or icoloclast?).

Teaching Interests

I am a member of the Bioinfomatics Trainers Network.

I jointly deliver the bioinformatics components of the cross-Faculty DDP in Proteomics-Informatics.

I organised a cross-Faculty training session in Metabolomics Cheminformatics.

I collaborate with EBI to deliver bioinformatics training through learned societies.

I lead the Literature Review Module in the MMedSci in Human Nutrition.

I developed and led the Research Skills Module (in 2011), the Molecular Nutrition Module (in 2008), and the Literature Review Module (in 2010) and the Clinical Nutrition Module (in 2002) in the MMedSci in Human Nutrition.
