Fig. 5

Representative western blots show JNK3 expression in a pcDNA3-FLAG-APP695 transfected or pcDNA3 transfected SH-SY5Y cells, e retinae from wild-type or APP-null mice, or i pcDNA4/V5-His-AICD59 or pcDNA4/V5-His transfected SH-SY5Y cells. The samples were lysed, resolved in SDS-page gel, and immunoblotted using antibodies against JNK3 or GAPDH. b, f, j The bar charts show quantitative analysis of relative JNK3 expression (n = 3 for each experiment). Representative western blots show phosphorylative activation of JNK3 in c APP695-overexpressing or normal SH-SY5Y cells, g retinae from wild-type or APP-null mice, or k pcDNA4/V5-His-AICD59 or pcDNA4/V5-His transfected SH-SY5Y cells. JNK3 was immunoprecipitated with anti-JNK3 antibody and then detected for kinase activity with anti-phospho-JNK (pJNK) or anti-JNK3 antibody. Whole-cell lysate western blots show the downstream substrate pc-Jun73 or c-Jun level. d, h, l The bar charts show quantitative analysis of activated pJNK/mg lyate proteins or pc-Jun73/c-Jun ratio (n = 3 for each experiment). Student’s t-test: *p < 0.05; **p < 0.01. Error bars represent SEM
