A, TTA-P2 abrogates Ang II-stimulated aldosterone secretion from human adrenal slices. B, Statistical analysis of TTA-P2 induced inhibition of Ang II-stimulated aldosterone secretion. Data are presented as fold over control. *, P < 0.05 compared with control. #, p < 0.05 compared with Ang II alone (n = 4). C, TTA-P2 abrogates high K+-stimulated aldosterone secretion from human adrenal slices. D, Statistical analysis of TTA-P2 induced inhibition of high K+-stimulated aldosterone secretion. *, p < 0.05 compared with control.#, p < 0.05 compared with high K+ alone (n = 5).
