cAMP and glucocorticoid regulate Creb3l1 expression. AtT20 cells were used to study regulation of Creb3l1. ac AtT20 cells were treated with 10 μM FSK or vehicle (DMSO). a Creb3l1 mRNA expression was observed by qPCR at various time points (n = 3; One way ANOVA). bc Immunoblotting was performed to examine protein expression level of CREB3L1 in both b total protein extracts and c cytosolic/nuclear extracts. de AtT20 cells were treated with vehicle (DMSO), 10 μM FSK and/or 100nM DEX at various time points. d Effect of glucocorticoid on c-Fos and Creb3l1 expression was examined by qPCR (n = 3; Two way ANOVA). e Immunoblotting of CREB3L1 was performed at 24 h after treatment. GAPDH was used as an internal control for immunoblotting. * in B and E indicates non-specific band in immunoblotting. * in D indicate significant from FSK + DEX compared to FSK group. Scale bar, 20 μm; Error bar, +SEM; *,< 0.05, **, p < 0.01; ***, p < 0.001; FSK, forskolin; DEX, dexamethasone
