  • Haematopoiesis, Acute Myeloid Leukaemia, Mixed Lineage Leukaemia, Chromatin biology, gene regulation

Research overview

The Gilan laboratory at the Australian Centre for Blood Diseases explores how the epigenetic landscape of leukaemia cells is altered and the role it plays in the maintenance of the leukemic state. We aim to understand how the dynamic nature of the epigenome facilitates the response and adaptation (resistance) to targeted therapies. Ultimately the goal is to leverage these insights to identify strategies to reset the cancer cells back to their normal state for therapeutic benefit.

What we are interested in

Fundamental to our understanding of the role of the epigenome in cancer is the intricate world of gene regulation. Gene regulation is an incredibly complex process that underpins the immense diversity of multicellular organisms. Broadly speaking, we aim to make sense of how the many layers of chromatin regulation (epigenome) are linked together to control gene expression. Acute Myeloid Leukaemia (AML) is a devastating disease with a clinically unmet need. It is highly heterogeneous but is caused by relatively few mutations that invariably converge on a block of differentiation and increased self-renewal of blood progenitor cells. Our work spans cellular biology, molecular biology and biochemistry. We utilise a wide variety of cutting edge techniques in the genomics field such as RNA-seq, ChIP-seq, ATAC-seq, CRISPR, CRISPR screens, and mouse models to understand how current and emerging therapies function and to discover new therapeutic targets.
