C03 Epigenetic regulation of esophageal cancer

Silke Laßmann

Silke Laßmann

Principal investigator of

Esophageal cancers still represent a major challenge in interdisciplinary oncology. This project explores the epigenetic regulation of oesophageal cancers with respect to its pathobiology and therapeutic potential. We shall evaluate how histone modifiers guide squamous to intestinal cell differentiation in the development of oesophageal adenocarcinomas and establish in a genome-wide approach patterns of histone marks, transcriptomes, and mutational profiles. This project aims to validate epigenetic inhibitors for oesophageal cancer in a preclinical setting.
