Research Interest: Understanding the factors and mechanisms affecting genetic instability and epigenetic remodelling in the context of hepatocellular carcinoma (HCC)
Summary: HCC is the sixth most common type of cancer and the second most frequent cause of cancer-related deaths worldwide. Over 70% of patients have incurable disease at presentation, due to late detection. The combination of rising incidence and lack of treatments has contributed to marked increases in HCC mortality – which is predicted to continue increasing for the next 20 years. Hence, much clinical research is focused on developing novel more effective therapeutic options for these patients. It is widely recognized that to have a major impact on survival, early detection and better treatment strategies are urgently required. Hence my focus is the identification of novel therapeutic target(s) and diagnostic and treatment stratification biomarkers for HCC patients.
The main focus of the lab is to identify and characterise epigenetically deregulated therapeutic targets, primarily L1 autonomous retrotransposons. Also, we are exploring DNA methylation patterns in HCC samples to identify potential Synthetic Lethal genes and evaluate them as novel therapeutic targets for HCC. Activation of retrotransposons has been well documented in cancers of different origins leading to an increase in genetic instability by promoting gene deletions/duplications and genomic rearrangements. Active retrotransposons can influence gene expression patterns, generate truncated or antisense gene transcripts and alter splicing patterns [1, 2]. I have demonstrated that active retrotransposition is associated with activation of oncogenic pathways in hepatocellular carcinoma (HCC) [3,4]. However, the mechanism/factors leading to activation of retrotransposons during cancer development are unclear. Hence the research questions we are addressing are: the relationship between the activation of L1s and HCC status and the mechanism (s) of retrotransposons activation in the context of HCC.
In parallel, we are aiming to identify diagnostic, prognostic and treatment stratification biomarkers by focusing on gene expression changes and DNA methylation in peripheral immune cells and circulating cell-free DNA and RNA to develop 'liquid biopsy tools'. The ultimate aim is to develop potential therapeutic strategies and biomarkers for HCC patients in order to reduce lethality associated with the disease.
