Chd4 controls Ripk3 dependent necroptosis during muscle regeneration


ABSTRACT: We performed a label-free LC-MS/MS study to analyse the role of Chd4 regulation in MuSC in suppressing genes enabling programmed cell death as part of the muscle regeneration program. Lox-cre recombination was used to create a deletion mutant of the CHD4 chromatin modifier (exons 12-21). A pseudo "infection" with GFP was used as control. Proteomics analysis here serves as a method to compare the differentially deregulated proteins upon knockdown of Chd4 in MuSCs using Adenoviral CRE recombination.

Somatic stem cells expand massively during tissue regeneration, which might require control of cell fitness, allowing elimination of non-competitive, potentially harmful cells. How or if such cells are removed to restore organ function is not fully understood. Here, we show that a substantial fraction of muscle stem cells (MuSCs) undergo necroptosis because of epigenetic rewiring during chronic skeletal muscle regeneration, which is required for efficient regeneration of dystrophic muscles.
