MAP2K2 and Duchenne muscular dystrophy: Furthermore, analysis of the correlation between the five significantly different immune cell types, nine DMD-related DEMs, and nine DELs in the DMD-related lncRNA-mRNA pathway network revealed that activated NK cells, neutrophils, and Tregs were positively correlated with the expression of four DELs (CCDC18-AS1, DBET, MBNL1-AS1, and MIR29B2CHG) and one DMD-related DEM (MAP2K2), whereas the cells were negatively correlated with the expression of the other five DELs and eight DMD-related DEMs.
