Epigenetic control of gene expression and genome stability
Epigenetics and Chromatin Biology
In multicellular organisms, every cell contains nearly identical genetic information. However, there is an amazing diversity of cell types that perform varieties of functions. Cellular identity and differentiation are therefore not determined by the DNA sequence itself but by the expression of selected genomic regions in time and space. At the molecular level, these transcriptional programs are controlled by so-called epigenetic processes guiding each single cell towards its own fate. Failures in epigenetic pathways are often at the heart of human diseases such as cancer. Furthermore, reprogramming the genome using epigenetic tools is rapidly emerging as a powerful approach to improve human health or plant fitness. The research in the Bischof lab aims at understanding the role of the epigenome on a cell’s behavior, ultimately paving the way for improving both human health and agriculture.
