For instance, recent work from Ferlini's lab studied chitosan‐shelled nanobubbles as a DDS for PMO ASO to suppress the expression of Double homeobox 4 (DUX4) in a facioscapulohumeral muscular dystrophy (FSHD) cell model (Falzarano et al., 2021). This evidence concerns the gene DUX4 and muscular dystrophy.
