Gene regulation in cancer, in particular epigenetic gene regulation, has been the major focus of Professor Susan Clark's research efforts. Epigenetic means a modification of the DNA and associated chromatin that changes the expression pattern of genes without changing the DNA sequence of the genes. DNA methylation of cytosine residues at CpG dinucleotides is one example of epigenetic gene regulation. Methylation of the promoter sequences of genes is a common process used in the cell to control and modulate the expression of genes. However in cancer the DNA methylation pattern of many genes changes. In fact methylation is a critical component associated with the silencing of many tumour suppressor and related genes in a variety of cancer types.
