Duchenne muscular dystrophy (DMD) involves muscle wasting due to dystrophin absence. This review explores how calcium (Ca2+) imbalance contributes to DMD weakness and potential treatments targeting this dysregulation.
Area of Science:
- Biomedical Science
- Genetics
- Cellular Biology
Background:
- Duchenne muscular dystrophy (DMD) is an X-linked genetic disorder resulting from dystrophin deficiency.
- DMD leads to progressive muscle degeneration, damage, and impaired repair.
- The precise mechanisms of muscle dysfunction in DMD are not fully understood.
Purpose of the Study:
- To review the role of intracellular calcium (Ca2+) homeostasis abnormalities in DMD.
- To explore potential therapeutic strategies that address Ca2+ dysregulation in muscular dystrophy.
Main Methods:
- Literature review focusing on studies investigating calcium handling in DMD.
- Analysis of research on the link between Ca2+ dysregulation and muscle weakness in muscular dystrophy.
Main Results:
- Elevated intracellular Ca2+ is implicated as a cause or facilitator of muscle weakness in DMD.
- Aberrant Ca2+ homeostasis is a significant factor in the pathophysiology of dystrophic muscle.
Conclusions:
- Targeting Ca2+ dysregulation presents a promising therapeutic avenue for Duchenne muscular dystrophy.
- Further research into counteracting Ca2+ abnormalities could lead to effective DMD treatments.

Cross-bridge Cycle
Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open....

Feedback Regulation of Calcium Concentration
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...
Smooth Muscle Contraction
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...

The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...
