Bradykinin (BK) induced endothlin-1 (ET-1) secretion in B16-BL6 melanoma cells. Fentanyl inhibited BK-induced ET-1 secretion in B16-BL6 cells. The action of fentanyl was attenuated by naloxone methiodide. B16-BL6 cells expressed ET-1, kinin B2 receptors, and μ-opioid receptors (MOR). The results suggest that fentanyl regulates BK-induced ET-1 secretion through MOR.
