Pancreatic neuroendocrine tumours (PNETs) arise from hormone-producing cells of the pancreas, such as the insulin and glucagon-producing cells. Current treatment of PNETs involves surgery, pharmacological therapies or peptide receptor radionuclide therapy (PRRT). The 5-year survival of PNET patients varies according to whether the tumour has spread but may be as low as 30-40% for metastatic, unresectable disease. Therefore, we urgently need a better understanding of the causes of PNET, as this may help to develop better treatments. Genome sequencing studies have revealed that PNETs frequently harbour inactivating mutations in the MEN1 tumour-suppressor gene. MEN1 encodes a protein that is part of a protein complex that regulates gene transcription. It promotes methylation of histone H3 at lysine 4 (H3K4), an epigenetic histone mark that is associated with activation of transcription. At the University of Melbourne Centre for Cancer Research, we have sequenced the tumour genomes of a cohort of PNETs. These tumours display novel MEN1-related genomic alterations that appear enriched within our cohort.
This Honours project will aim to answer interesting questions arising from these observations using a mix of laboratory and bio-informatic analyses. This exciting project has the potential to yield new insights that will grow our knowledge of MEN1 and PNETs that will benefit cancer patients.
