...Susan K. Fellner; Laurel Parker SUMMARY In vascular smooth muscle (VSM) of Squalus acanthias , endothelin-1(ET-1) signals via the ET B receptor. In both shark and mammalian VSM, ET-1 induces a rise in cytosolic Ca 2+ concentration([Ca 2+ ] i ) via activation of the inositol trisphosphate (IP 3...
