(a) Effect of CMC on cytosolic Ca2+ in L6 cells. CMC maximally stimulated release of Ca2+ 1 mM. Data are means ± SEM, n = 4. (b) CMC does not alter ryanodine sensitivity. The solid line indicates control cells. The dashed line indicates the presence of 1 mM CMC. *P < 0.05 versus control, n = 4. (c) Variation of external calcium does not affect ryanodine sensitivity. The dotted line indicates control cells (with 1 mM externally added calcium). The dashed line indicates the presence of 2 mM externally added calcium. *P < 0.05 versus Control, n = 4.

CMC: 4-chloro-m-cresol
