Cancer originates from normal cells through genetic and epigenetic alterations. By employing forward genomic screening we start from a known gene mutation or cancer-associated condition and investigate the path that results in a manifest malignancy. Major further focus areas of the lab include: oncoprotein-induced disturbance of post-translational protein modifications, in particular SUMOylation, and sensing of DNA damage; constitutively activated B-cell receptor and chemokine receptor signaling; and molecular cancer imaging and theranostics.
