Effect of E2 and related compounds on AMT activity, NO release, and calcium levels in HUVECs.

Dependence of AMT activity (A), NO release (B), and intracellular calcium levels (C) on the concentration of E2, E2-BSA, epi-E2, or cortisol. Values are reported as means ± SD. In all panels, *P < .01 and **P < .05 compared with untreated control (P > .05 in all other cases).
