We tested the effects of 17β-estradiol as well as its catechol- and methoxy-derivatives, two androgens (DHEA and testosterone), a glucocorticoid (cortisol), a mineralocorticoid (aldosterone), and progesterone on the activity of ERK1,2, a key component of the ERK/MAPK enzyme phosphorylation cascade, in SW-13 human adrenal carcinoma cells. After a 24-hour exposure SW-13 cells incubated with 10-5 M concentrations of 17β-estradiol, its 2-hydroxy or its 2-methoxy derivative, all had elevated ERK activities (196 %, 159 %, and 275 %, respectively) relative to control cells (p < 0.01). Incubation with testosterone resulted in 162 % of control ERK activity (p < 0.01), whereas incubation with the far weaker androgen DHEA or with cortisol, aldosterone, or progesterone had no significant effects. These findings suggest sex steroid-specific influences in the induction or activation of signal transduction pathways known to play a crucial role in cellular proliferation and differentiation.
