MMP9 and Duchenne muscular dystrophy: Interestingly, other genes of interest found to be dysregulated in primary mouse myoblasts were found to have non-orthologous counterparts dysregulated in human primary DMD myoblasts: COL11A1, COL14A1 and COL15A1 for Col2a1, Col4a1, Col4a2, and Col8a2 or MMP2 for Mmp3, Mmp9, and Mmp10.
