CCN2 and Duchenne muscular dystrophy: Fibronectin was described as a seric biomarker of Duchenne muscular dystrophy (DMD) (Cynthia Martin et al., 2014), and its expression during fibrosis has been shown to be regulated by TGFB1 and CTGF (Vial et al., 2008), whose expression patterns follow those of FN1 in our study (Table 2 and Figure 8).
