The Drier Lab for Systems Biology of Cancer: Uncover genomewide dysregulation of regulatory elements behind cancer
Cancer is driven by genetic and epigenetic changes to the DNA. We now know quite well how genetic alterations of genes drive cancer, thanks to extensive mapping efforts. However, we still know very little about the extent and function of genetic and epigenetic alterations at regulatory regions away from genes.
Other than expanding our understanding of gene regulation and dysregulation in cancer, we aim to leverage this knowledge to predict novel therapeutic targets for the development of new drugs, and develop models to predict patient outcome to help guiding treatment plans for cancer patients.
Our scientific approach combines epigenetic profiling, development of computational models and algorithms, and experimental validation. We combine cutting edge experimental techniques with developing new machine learning algorithms and big-data analytical approaches.
We study how genetic and epigenetic alterations of regulatory DNA elements cause cancer or contribute to the disease. We focus on two types of regulatory DNA elements: enhancers (regulating transcription), and CTCF binding sites (regulating chromosomal topology, i.e. the folding of the chromosome in 3D).
Epigenetic topological alterations in cancer
Genetic dysregulation of DNA regulatory elements in cancer
We develop systematic approaches to integrate genetic, epigenetic, topologic and transcriptional information to study how genetic alterations affect the function of regulatory DNA elements. For example, we have recently uncovered how genetic translocations alter the targets of enhancers to rewire the gene regulatory network into a positive feedback loop . We are now working to extend such approaches to comprehensive analysis of functional regulatory DNA alterations across cancer.
