The syncytiotrophoblast of the placenta is the site of exchange of nutrients and minerals between the mother and fetus. We have recently demonstrated that PTH influences, in vitro, phosphate transport through the placenta brush border membranes (BBM) and increases cAMP
PTH receptors on two stable clonal rat osteosarcoma cell lines, ROS 17/2 and ROS 17/2.8, were characterized using an HPLC-purified, synthetic, sulfur-free, radioiodinated analog of bovine PTH, [Nle8,Nle18,Tyr,34]bovine PTH-(1-34)amide. PTH binding is specific for PTH agonists and antagonists and is
Most studies of PTH receptor binding have been carried out with amino-terminal radioligands which only detect binding within that region of the hormone molecule. We studied the binding of electrolytically labeled intact bovine PTH [bPTH-(1-84)], and its amino-terminal fragment, bPTH-(1-34)

In this article we demonstrate receptors for parathyroid hormone in circulating mononuclear leukocytes using the radioiodinated analogue (8,18 norleucine, 34 tyrosine) bPTH 1-34 (bovine parathyroid hormone 1-34). Specific binding, which is reversible and saturable, equilibrates within 5 min at 0-4

The fractional hepatic extraction (FHE) of oxidized 125iodine-labeled bovine parathyroid hormone, 125I-bPTH-(1-84), is dependent on the integrity of the 28-48 sequence of the bPTH structure. A second type of FHE, related to the biologically active core of the hormone, is
