ELAVL1 and familial dilated cardiomyopathy: To investigate potential associations between DMD-linked DCM and HuR modulation, we analyzed cardiac tissues from dystrophic mdx mice at various stages: pre-onset (3 m), onset (9 m), and during DCM progression (14m and 18m), comparing them to age-matched healthy C57Bl (WT) mice (Fig. 1).
