Intracellular free calcium concentration [( Ca2+]i) of human peripheral blood lymphocytes was determined by fluorescence spectroscopic measurements with quin2 in patients with different types of muscular dystrophy and in controls. The [Ca2+]i level in lymphocytes showed a significant increase in adult type (facioscapulohumeral and limb-girdle) muscular dystrophies, while it showed a decrease in Duchenne dystrophy as compared to the values of age- and sex-matched controls. The data obtained suggest an alteration in the effectiveness of the calcium pump in lymphocytes and may represent a sign of generalized membrane damage in these hereditary muscle diseases.

Duchenne muscular dystrophy (DMD) is the most common form of muscular dystrophy with no cure currently available. In this study, using two microarray data sets obtained from the Gene Expression Omnibus database, we conducted a dysfunctional pathway-enrichment analysis and investigated deregulated genes that are specific to different phases of the disease in order to determine pathogenic characteristics in the progression of DMD. We identified 41 and 33 dysfunctional pathways that were enriched with differentially expressed genes in presymptomatic patients and in symptomatic patients, respectively. Over 70% of pathways were shared between both phases and many of them involved the inflammatory process, suggesting that inflammatory cascades were induced soon after the birth of the patients. Further investigation showed that presymptomatic patients performed better with respect to muscle regeneration and cardiac muscle calcium homeostasis maintenance. Neuronal nitric oxide synthase, dihydropyridine receptors, sarcoplasmic/endoplasmic reticulum calcium ATPase, and phospholamban may serve as potential targets for further molecular diagnostic tests. Our results may provide a better understanding for the treatment of DMD.
