the very high sensitivity to calcitonin of the adenylate cyclase contained in these three segments ( 0.01 ng/ml of salmon calcitonin inducing a 2-fold stimulation ; half-miximal stimulation corresponding to about 0.3 ng/ml of salmon calcitonin ) suggests that the distal convoluted tubule , as well as th cortical and medullary portions of the thick ascending limb of the loop of henle represent physiological target structures of calcitonin action within the kidney .
