Genetic basis for resistance to parathyroid hormone.
Pseudohypoparathyroidism (PHP) is associated with biochemical hypoparathyroidism (i.e. hypocalcemia and hyperphosphatemia) due to parathyroid hormone (PTH) resistance rather than to PTH deficiency. Patients with PHP type 1a have a generalized form of hormone resistance plus a constellation of developmental defects termed Albright hereditary osteodystrophy (AHO). Within PHP type 1a families some...
متن کاملCirculating parathyroid hormone-related protein (109-141) in malignancy-associated hypercalcemia.
For differential diagnosis between hypercalcemia-induced bone metastasis and humoral hypercalcemia of malignancy (HHM), serum parathyroid hormone-related protein (PTHrP) concentrations were measured in normal subjects and patients with malignancy-associated hypercalcemia according to the presence or absence of bone metastasis, using a new sensitive PTHrP(109-141) radioimmunoassay system. The se...
متن کاملCirculating levels of biologically active parathyroid hormone in rheumatic diseases.
There has been doubt as to whether elevated levels of parathyroid hormone, reported previously by radioimmunoassay, reflect increased concentrations of the biologically active hormone. The application of a recently developed, highly sensitive bioassay has shown considerable disparity between bioactivity and immunoreactivity in 5 rheumatic conditions and in normal subjects. Six patients with cho...
متن کاملCirculating bovine lymphocytes contain receptors for parathyroid hormone.
No cell type practicably obtainable in vivo, such as blood cells, is known to contain parathyroid hormone (PTH) receptors; this deficiency has hampered investigation of receptor regulation. Second, PTH in vivo is among the potent stimulators of osteoclastic activity, although no direct hormonal effects on these cells have been identified. Several lines of evidence suggest that cells of the immu...
متن کاملParathyroid hormone receptors in circulating human mononuclear leukocytes.
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 degrees C with a calculated KD of 8.9 X 10(-11) M. This binding has a pH maximum of 7.0, is magnes...
