Figure Lengend Snippet: A. Left: Representative REST immunoblots of primary cortical neurons (DIV14) treated with the cell-permeable competitive Ca 2+ -calmodulin antagonist W7 (20 µM). Calnexin was used as a control for equal loading. Right: Mean (± sem with individual experimental points) REST protein expression shown as a ratio between REST and calnexin immunoreactivities. **p=0.0071; unpaired Student’s t -test (n=5 independent neuronal preparations). B. Left: Representative REST immunoblots of DIV 14 primary cortical neurons treated with the phosphatase inhibitor cyclosporin A (CsA; 1 µM). Calnexin was used as a control for equal loading. Right: Mean (± sem with individual experimental points) REST expression shown as a ratio between REST and calnexin immunoreactivities. p=0.36; unpaired Student’s t -test (n=5 independent neuronal preparations). C. Left: Representative REST immunoblots of DIV14 primary cortical neurons treated with vehicle (Ctrl), the cell-permeable CaMK inhibitor KN93 (10 µM), or its inactive derivative KN92 (10 µM). Calnexin was used as a control for equal loading. Right: Mean (± sem with individual experimental points) REST protein expression shown as a ratio between REST and calnexin immunoreactivities for the three treatments. *p=0.031, Ctrl vs KN93; *p=0.032, KN93 vs KN92; one-way ANOVA/Holm-Sidak’s tests (n=5 independent neuronal preparations).
