(a,d,g) Experimental protocol: hippocampal CA1 minislices were prepared from adult rats and were stimulated by TBS in the absence or presence of CI-III (10 μM), as indicated. (b,e,h) Representative western blottings for SCOP, Akt, p-ERK and ERK under various experimental conditions. (c,f,i) Quantitative analysis of the levels of SCOP (normalized to the values of Akt) and p-ERK/ERK ratios under various experimental conditions. Results are means±s.e.m. of three to eight experiments. *P<0.05, as compared with time point 0, one-way analysis of variance followed by Bonferroni test.
