Our Research

In the past we have analysed data from yeast to human to understand why some genes are harmful when they are overexpressed. Increased gene dosage, as for example by gene amplification, is associated with diverse human pathologies, including cancer. We have also studied the origins and stability of genetic redundancy, the phenomenon whereby mutations in many genes have little effect on an organism. A better understanding of genetic redundancy, or buffering, may offer insight into how to target cancer cells where this redundancy is failing.

More recently we have shown that sequence composition determines the packaging of the human genome in the male germline. GC-rich sequences remain packaged in nucleosomes in the male gametes. This raises the possibility that at these GC-rich sites epigenetic information can be transmitted from one generation to the next.  Understanding how and to what extent epigenetic information can be transmitted between generations is important because in the long term it may help us predict better disease risk in individuals.

We are currently studying how the promoter type of human genes affects their chromatin organization. We recently showed that genes with CpG-island promoters have distinct chromatin from genes with other types of promoter. Cancer cells often have very different epigenetic marks from normal cells. Our aim is to understand how global epigenetic changes, associated with cancer or induced by anti-cancer therapeutic drugs, affect the regulation of different types of human genes.
