Dr I. Jane Cox PhD, FRCP Hon

Principal Investigator

Head of the Metabonomics Group

Researching biomarkers of liver damage using metabolic profiling of urine, blood, and intact liver tissue. 

The aim is to provide earlier markers of liver disease before symptoms are obvious clinically, for example the early indications of liver cancer.

Research:

Dr Cox is particularly interested in using NMR spectroscopy techniques to provide a non-selective snapshot of a range of metabolic processes. These studies can also be used to document liver disease progression, including the impact of the microbiome in patients with cirrhosis. 

Projects:

  1. Magic angle spinning NMR studies of intact liver tissue (for example, DOI: 10.1016/j.jhep.2009.10.006) to document metabolite differences between liver tissue from hepatocellular carcinoma (HCC) and surrounding liver tissue, obtained at the time of liver resection, and to correlate metabolite changes with clinical and laboratory immunological findings. Collaboration with Drs Shilpa Chokshi & Antonio Riva.
  2. To investigate how dietary changes can modulate gut microbiota and interact with cirrhosis. Our aim is to define gut microbial functional and metabolomic changes to understand disease processes and to increase insight into the impact of dietary intervention in patients with liver disease. For example, DOI: 10.1111/liv.15329.
  3. In collaboration with Dr Neil Youngson and Professor Luca Valenti, we investigated the role of the gut in affected COVID-19 patients, grouped according to mild and moderately severe disease. We propose that the reduced circulating FABP2 in moderate to severe COVID-19 is a marker of infected enterocyte functional change rather than gut damage, which could also contribute to the development of hypolipidemia in patients with more severe disease. doi: 10.1038/s41598-022-23282-x
