Epigenomics of Breast Cancer


Thomas Fleischer
ResearcherID: T-8066-2017

Both genetic and epigenetic alterations can control the progression of cancer. Epigenetics comprises several alterations to the DNA molecule that may alter the binding of proteins and thereby the expression of genes, and our knowledge about cancer-promoting epigenetic alterations is mostly limited to DNA methylation at promoters of tumor-suppressor genes. Today it is known that most cancer types harbor much more widespread and frequent epigenetic alterations, and the functional effect of these alterations still remains unclear.

The overarching aim of the project group is to increase our understanding of the causal effects of epigenetic alterations in breast cancer, and to utilize this knowledge to develop classification of breast cancer patients with clinical utility.
