Apical membranes of Aplysia californica foregut epithelia contain a sodium-phosphate symporter. Dexamethasone inhibited the absorptive activity of the sodium-phosphate symporter, whereas amiloride had no effect on the sodium-phosphate symporter. It appears that glucocorticoids or their molluscan equivalent play a role in the overall regulation of phosphate homeostasis by the Aplysia californica gut.
加州海兔前肠上皮的顶端膜含有一种钠-磷酸盐协同转运蛋白。地塞米松抑制了钠-磷酸盐协同转运蛋白的吸收活性，而氨氯地平对钠-磷酸盐协同转运蛋白没有影响。看来糖皮质激素或其在软体动物中的等效物在加州海兔肠道对磷酸盐稳态的整体调节中发挥作用。
