As head of the Cancer Therapeutics Group, Professor Ross Hannan's work focuses on the molecular analysis of major pro-malignant transcription factor networks that operate in cancer cells using an integrated approach that combines cell biology, genomics, proteomics, biochemistry, genetics, bioinformatics and strong interactions with oncologists in the clinic. Through this molecular understanding, he hopes to identify key therapeutic nodes to impede the progression of aggressive cancers. The availability of ribosomes is a fundamental rate-limiting step for tumour cell proliferation. He is examining the genetic and epigenetic processes by which ribosomal RNA gene transcription, is regulated by RNA Polymerase I, and how this process is dysregulated during cancer.
Professor Hannan and his group have progressed this fundamental research a step closer to treating patients and changing clinical practice. His group developed the world’s first selective inhibitors of Pol I transcription (Bywater et al. Cancer Cell 2012; Bywater et al., Nature Reviews Cancer 2013), which are a new class of therapeutic. This inhibitor is currently in Phase I clinical trials at Peter Mac for the treatment of haematological malignancies. His lab is also involved in the development of second-generation drugs and evaluating their effectiveness in other cancers such as ovarian and prostate.
The second area of research focus for Professor Hannan is ribosomopathies, a group of inherited diseases including Diamond Blackfan Anaemia (DBA) and myelodysplastic (5q-) syndrome. Such patients are also predisposed to developing haematological malignancies such as acute myeloid leukaemia (AML). Ribosomopathies are caused by dysregulated ribosome biogenesis. Thus understanding the mechanisms mediating these diseases may identify novel approaches for their treatment, which at this time is palliative only.
Professor Hannan’s group has utilized genome-wide and chemical screening to identify potential candidates, which underlie the genetic and/or functional cause of various ribosomopathies. Expanding from this understanding the mechanisms underlying the increased predisposition for patients with ribosomopathies to develop cancers such as AML is also being evaluated.
Professor Hannan is a Group Leader at the Peter MacCallum Cancer Centre in Melbourne in The Oncogenic Signalling And Growth Control Program.
Enquiries are welcome from potential Honours or PhD students. A variety of projects are available within all of the areas of research undertaken by this Group.
