Activation of EGF receptors and of ERK is required for up-regulation of mRNA expression of c-fos and fosB by fluoxetine in astrocytes. Cells were incubated for 60 min in serum-free medium in the absence of any drug (Control) or in the presence of 10 μM fluoxetine alone or together with 1 μM AG 1478 or 10 μM U0126. Average mRNA expression (n = 3) was quantitated as ratios between c-fos and TBP, used as a house-keeping gene (A) and between fosB and TBP (B). SEM values are indicated by vertical bars. *Indicates statistically significant (P < 0.05) difference from Control, AG 1478, fluoxetine plus AG 1478, U0126, and fluoxetine plus U0126 groups for c-fos and fosB.
