From: Dietary selenium augments sarcoplasmic calcium release and mechanical performance in mice
Selenium treatment augmented KCl depolarization evoked Ca2+ transients and resting [Ca2+]i in FDB fibers. Depolarization evoked changes in intracellular calcium concentration in FDB muscle (a) of control (left), 0.5 ppm NanoSe (middle) and 0.5 ppm selenate (right) feed mice. Average values of resting [Ca2+]i (b), change in [Ca2+]i (∆[Ca2+]i) (c) and maximal rate of rise of the transients (d). Numbers in parenthesis give the number of fibers investigated. * and *** denote significant difference from control at levels of P < 0.05 and P < 0.001, respectively
