Hepatic Fibrosis

Professor Grant Ramm

Group Leader

The Hepatic Fibrosis Laboratory investigates the cellular and molecular mechanisms of scar tissue formation in the liver. This leads to fibrosis and cirrhosis in adult liver diseases such as haemochromatosis and in children in diseases such as cystic fibrosis and biliary atresia. If left untreated chronic liver disease can lead to liver cancer.


  • Development of microRNAs as anti-fibrotic agents to treat organ fibrosis
  • Characterisation of anti-inflammatory molecules and signalling pathways to treat liver inflammation, fibrogenesis and cirrhosis.
  • Non-invasive biomarkers of liver disease and fibrosis in haemochromatosis
  • Elastographic assessment of liver stiffness (fibrosis) in children with CF liver disease
  • Molecular and cellular basis of hepatic stellate cell activation in fibrogenesis associated with chronic liver disease
  • Serum microRNAs to detect and monitor disease progression in liver disease sequelae including cirrhosis and liver cancer.

Anti-inflammatory small molecule inhibitor development to control liver inflammation associated with hepatic fibrosis in chronic liver disease

Projects can be adapted to suit Honours, PhD or clinical students. Inflammation is integral in driving early liver scarring (fibrogenesis). The association between hepatic inflammation and circulating ferritin levels in chronic liver disease is well known. However, rather than simply acting as a marker of inflammation, our research has demonstrated that the H-subunit of Ferritin […]

MicroRNAs as anti-fibrotic agents to treat liver scarring, fibrosis and cirrhosis in chronic liver disease

Projects can be adapted to suit Honours, PhD or clinical students. Virtually all biological processes in eukaryotic cells are regulated by microRNAs that control protein-coding gene expression. Our laboratory has identified a number of different microRNAs that regulate the expression of collagen in liver disease and that can be manipulated to control liver scarring or […]
