Immunoblottings indicated that the energy costly process of autophagy was decreased in DMD whereas it was maintained in BMD (Figure4D), as suggested by the expression of the autophagy‐inducing protein BCL2/adenovirus E1B 19 kDa protein‐interacting protein 3 (BNIP3), which was decreased in DMD and increased in BMD. Here, BNIP3 is linked to Becker muscular dystrophy.
