Description and Objective

The intestinal epithelium is constantly exposed to a harsh digestive environment and to toxins, and regenerates rapidly to maintain the protective barrier. Various gastrointestinal diseases, such as inflammatory bowel diseases, can be promoted or exacerbated by toxic influences in conjunction with a defective barrier function and insufficient regeneration. Following damage, the tissue is rebuilt through cellular plasticity, whereby lost stem cells are also replaced. It remains unclear how this regeneration is orchestrated and how the cells cope with repeated injuries. This work therefore aims to investigate epigenetic mechanisms, specifically the histone methyltransferase MLL1, in regeneration as well as in the adaptive and intrinsic resilience of the intestinal epithelium. This project comprises in vivo experiments and in vitro organoid experiments. Corresponding experiments using the mouse model were conducted in collaboration at the Charité and have been completed. The project has now been transferred to the BfRshort forGerman Federal Institute for Risk Assessment for finalization and for the conduct of in vitro experiments.
