Study TitleMuscle-specific Ryanodine Receptor 1 Properties Underlie Limb-Girdle Muscular Dystrophy 2B/R2 Progression
Study SummaryRyanodine receptor 1 Ca2+ leak is a signal in skeletal muscle, but chronic leak can underlie pathology. Here we show that in healthy male mouse, limb-girdle muscle presents higher sympathetic input, elevated ryanodine receptor 1 basal phosphorylation, Ca2+ leak and mitochondrial Ca2+ content compared to distal leg muscles. These regional differences are consistent with heat generation in resting muscle to maintain core temperature. The dysferlin-null mouse develops severe pathology in the limb-girdle but not leg muscles. Absence of dysferlin disrupts dihydropyridine receptors’ inhibitory control over ryanodine receptor 1 leak, synergistically increasing leak through the already phosphorylated receptor of limb-girdle muscle, altering Ca2+ handling and distribution leading to reactive oxygen species production prior to disease onset. With age, oxidation of Ca2+ -handling proteins in dysferlin-null limb-girdle muscle exacerbated basal Ca2+ movements. Our results show that muscle-specific pathology in dysferlin-null mice is triggered by increased ryanodine receptor 1 Ca2+ leak.

Collection:

Collection ID:CO003911
Collection Summary:Male C57Bl/6J mice were housed with standard chow food and water ad libitum. Mice were euthanised by cervical dislocation and skeletal muscle samples (psoas and tibialis anterior) were rapidly excised and frozen.
Sample Type:Muscle

Treatment:

Treatment ID:TR003927
Treatment Summary:No treatment. Skeletal muscle obtained from two distinct sites of male C57BL/6J mice (Ps=psoas; TA=tibialis anterior).

Sample Preparation:

Sampleprep ID:SP003924
Sampleprep Summary:~50 mg tissue samples were cryoground, homogenised with zirconium oxide beads in MeOH/water (1:1), extracted with CHCl3, and aqueous phase lyophilised (GeneVac MiVac Duo, max temp 35 *C). Samples were stored at -80 *C prior to analysis. Samples were resuspended in 60 uL of ACN/H2O (1:1) and clarified prior to LC/MS.
