Figure 7.

Voltage dependence of SR Ca2+release in WT and DMDmdxmuscle fibers. (A) Values for peak SR Ca2+ release flux versus voltage in all tested WT and DMDmdx muscle fibers (data are from 29 fibers from seven WT animals and 27 fibers from seven DMDmdx animals). An identical symbol is used for fibers from a same animal. Each dataset was fitted with a Boltzmann function (superimposed lines). The inset in each graph shows the mean (±SD) values calculated using the average from fibers from a same animal (n = 7 in each group). (B) Corresponding values for the voltage dependency of the total amount of released Ca2+ in the two groups of fibers. Refer to the image caption for details.
