Data originated from three mice per genotype

Data originated from three mice per genotype. to question whether ZEB1 plays a role in MuSC myogenic progression in the context of muscle injury and regeneration. Using a chronic muscular dystrophic mouse [mdx (in mice [(+/?)] results in an increased and more prolonged immune infiltration and damage of their muscles in response to injury, as well as in a retarded and poorer muscle regeneration. ZEB1 transcriptionally represses the promoter and, compared to wild-type counterparts, (+/?) injured muscles show increased CCL2 secretion by their myofibers and MuSCs. Infiltrating macrophages from (+/?) injured muscles display a retarded transition to an anti-inflammatory phenotype, which corresponded to a deficient upregulation of phosphorylated p38-MAPK and of in response to injury. In vivo forced activation of p38 in (+/?) injured muscles revert their enhanced damage and poorer regeneration to the same levels than in wild-type injured muscles. Delayed and poorer regeneration in (+/?) injured muscles is accounted by the retarded transition of (+/?) macrophages, as well as their functional deficient MuSCs.

Notably, ZEB1 was not expressed in mdx damaged myofibers and/or with infiltration by immune cells.
