Epigenetic Control of Gene Expression in Leukaemia and Haematopoiesis

In plain English

AI plain-English summary

Most children with acute lymphoblastic leukaemia are now cured, but for a few rare subtypes the disease remains untreatable and often relapses. This project investigates the epigenetic changes—chemical modifications to the proteins that package DNA—that drive these incurable leukaemias. The problem is that standard treatments fail for these rare subsets, and doctors lack therapies tailored to their underlying biology. The researchers aim to map how inappropriate gene activation, caused by reversible epigenetic marks, fuels cancerous growth in these stubborn leukaemias. If successful, this work could lead to new drugs that target those reversible epigenetic changes, offering a treatment path for children who currently have none. Because epigenetic modifications are not permanent changes to the DNA sequence itself, they are in principle correctable—making them attractive targets for therapy. This is fundamental science focused on the molecular machinery of gene regulation. While the immediate goal is understanding the basic biology of these leukaemias, similar fundamental research into epigenetic mechanisms has already produced drugs for other cancers. A deeper grasp of how epigenetic errors drive these rare ALL subtypes could eventually translate into clinical options where none exist today.

View original technical description
Acute lymphoblastic leukaemia (ALL) in children used to be a disease that was untreatable. Thankfully, general care for ALL has greatly improved so that ~90% of children are cured. Unfortunately, there are still rare subsets of ALL that have a tendency to relapse and are untreatable. We are trying to understand the molecular details of these rare, incurable ALLs in order to design new therapies. In order to do this, we study how epigenetics impacts gene regulation. Genes are made up DNA, and they reside in the nucleus, where they act as hardware for the cell that needs to be "read" in order to be functional. When genes are read (or what we call "activated") inappropriately, this can cause aberrant behaviour such as cancerous growth. Epigenetics is information that is not stored directly in the DNA itself. For example, some epigenetic information is stored in chemical modifications carried by histone proteins that interact with DNA in a structure called chromatin. It is becoming clear not only that aberrant epigenetic changes are common in many human diseases such as leukaemia, but that these changes by their very nature are reversible. Our goal is to help design therapies that can target these reversible epigenetic changes.
