Effects of MEST depletion on phosphorylation of CREB/ATF1 and intracellular cAMP and cGMP levels. hMADS cells were transfected at confluence (d-2) with siRNAs targeting MEST (siMEST) or a control siRNA (siC). Adipocyte differentiation was induced 2 days later (d0) using complete differentiation medium. (a) Protein lysates of cells at d1, d2 and d3 were analysed by western blotting for phosphorylation of CREB and ATF1 (p-CREB and p-ATF-1), total CREB, MEST and β-Tubulin (Tubβ). Numbers above p-CREB bands reflect the results of densitometric analysis (ratio of p-CREB/CREB) and are presented relative to siC-transfected cells at d1. (b and c) Cells at d0 and d2 were analysed for intracellular levels of cAMP (b) and cGMP (c). Testing for significant differences in second messenger levels was performed by a paired t-test; *P<0.05.
