ABSTRACT

Introduction/Aims

Duchenne muscular dystrophy (DMD) is caused by pathogenic variants in the DMD gene, making muscle fibers susceptible to contraction-induced membrane damage. Given the potential beneficial action of cannabidiol (CBD), we evaluated the in vitro effect of full-spectrum CBD oil on the viability of dystrophic muscle fibers and the in vivo effect on myopathy of the mdx mouse, a DMD model.

Methods

In vitro, dystrophic cells from the mdx mouse were treated with full-spectrum CBD oil and assessed with cell viability and cytotoxic analyses. In vivo, fourteen-day-old mdx mice received 10 mg/kg/day of the full-spectrum CBD oil for 14 days. We analyzed creatine kinase (CK) levels, liver damage markers, and histopathology of the diaphragm (DIA) and quadriceps (QUA [myonecrotic fibers with positive IgG staining, regenerated fibers/central nuclei, the minimum Feret's diameter, the fibrosis area, the inflammatory area, the presence of macrophages, and NF-kappa B content]).

Results

In vitro treatment with full-spectrum CBD oil showed a dose-dependent cytotoxic effect; however, in vivo 10 mg/kg treatment was safe and effectively improved DMD histopathological assessment parameters in DIA and QUA: reduction of central nuclei: 1.7% ± 2.0% versus 22.4% ± 5.3% and 11.1% ± 10.7% versus 32.3% ± 4.6%; reduction of IgG+ myofibers: 0.6% ± 0.7% versus 8.4% ± 1.6% and 0.9% ± 0.3% versus 7.5% ± 1.0%; increase in myofiber size: 85.2 ± 3.2 versus 64.3 ± 4.0 μm and 106.5 ± 8.6 versus 81.2 ± 4.8 μm; decrease in inflammatory area: 6.2% ± 2.7% versus 15.1% ± 2.6% and 5.3 ± 4.1 versus 17.3% ± 2.8%; reduced macrophage area: 0.05% ± 0.1% versus 10.8% ± 4.3% and 1.0% ± 0.7% versus 10.3% ± 4.9%; NF-κB levels: 0.6% ± 0.1% versus 1.7% ± 0.2% and 1.7% ± 0.1% versus 5.2% ± 2.1%; and fibrosis: 5.6% ± 1.8% versus 12.0% ± 3.7% and 1.3% ± 0.5% versus 4.7% ± 1.5%. It also reduced serum CK.

Discussion

Full-spectrum CBD oil may represent a promising new approach to treating DMD, but its potential toxicity must be considered.
