Store-operated calcium entry in flexor digitorum brevis myofibers. Representative calcium tracings in wild-type (WT) (A), mdx (B) and mdx-transgenic (mdx-TG) (C) flexor digitorum brevis (FDB) fibers following sarcoplasmic reticulum (SR) depletion and add-back of calcium. (D) Basal intracellular calcium concentration ([Ca2+]i) in WT, mdx and mdx-TG FDB fibers. (E) [Ca2+]i during store-operated calcium entry (SOCE). Bars represent means ± SEM. *Statistically significant difference from WT mice.
