- Identification of carboxyl-terminal peptide fragments of parathyroid hormone in human plasma at low-picomolar levels by mass spectrometry.
- Zhang CX, Weber BV, Thammavong J, Grover TA, Wells DS.Author information NPS Pharmaceuticals, 383 Colorow Drive, Salt lake City, Utah 84108, USA. czhang@npsp.comAbstractFor decades, researchers have tried to identify the primary structures of circulating carboxyl-terminal parathyroid hormone (C-PTH) peptide fragments that may be present at only picomolar levels in human plasma. Although immunoassays and radiosequencing techniques have provided valuable fragment characterizations, no analysis has successfully determined their exact primary structures. In this work, for the first time, four human C-PTH peptide fragments, hPTH(34-84), hPTH(37-84), hPTH(38-84), and hPTH(45-84), have been identified from human plasma using MS-based methods. C-PTH peptide fragments were isolated from plasma samples by immunoaffinity extraction. The eluate was analyzed by capillary LC fractionation followed by MALDI-TOF-MS or by on-line coupling of nano-LC with ESI-TOF-MS. Both the MALDI- and the ESI-based approaches were capable of detecting C-PTH peptide fragments in human plasma at <10 pmol/L. The MALDI-TOF approach was effective in preliminary searches for C-PTH peptide fragments, but the use of high laser power limited the resolution necessary for accurate C-PTH peptide identification. The high mass resolution (10,000) and accuracy (10 ppm) attained by the ESI-TOF approach enabled unambiguous identification of these peptides. The four C-PTH peptide fragments identified in plasma samples from patients with chronic renal insufficiency were also found in the plasma of healthy women receiving recombinant human PTH either by subcutaneous injection or by intravenous infusion. This newly developed analytical capability should greatly enhance the understanding of PTH metabolism and parathyroid gland function.

- hPTH-fragments (53-84) and (28-48) antagonize the stimulation of calcium release and repression of alkaline phosphatase activity by hPTH-(1-34) in vitro.
- Duvos C, Scutt A, Mayer H.Author information German Research Centre for Biotechnology, Department of Gene Regulation and Differentiation, Mascheroderwag 1, D-38124 Braunschweig, Germany.AbstractDifferent C-terminal fragments of parathyroid hormone (PTH)-(1-84) in blood participate in the regulation of calcium homeostasis by PTH-(1-84), and an antagonizing effect for the large carboxyl-terminal parathyroid hormone (C-PTH)-fragment (7-84) on calcium release has been described in vivo and in vitro. In this study the smaller C-PTH-fragment (53-84) and mid-regional PTH fragment (28-48), which represent discrete areas of activity in the PTH-(7-84) molecule, were assayed for their effects on calcium release and alkaline phosphatase (ALP) activity in a chick bone organ culture system. Neither PTH-(28-48) nor PTH-(53-84) had any effect on calcium release into the medium and both fragments stimulated ALP activity in the bone tissue, suggesting that the cAMP/PKA signalling pathway was not affected by these fragments. However they suppressed the calcium release induced by PTH-(1-34) and attenuated the down regulation of ALP activity caused by PTH-(1-34), suggesting that the effect on the cAMP/PKA signalling pathway may be indirectly. In conclusion, the study shows that the PTH-fragments (53-84) and (28-48) antagonize the PTH-(1-34) induced effects on calcium release and inhibition of ALP activity in a chick bone organ culture system.

- Carboxyl-terminal parathyroid hormone fragments: role in parathyroid hormone physiopathology.
- D'Amour P, Brossard JH.Author information Centre de recherche, Centre hospitalier de l'Université de Montréal, Hôpital Saint-Luc et Département de médecine, Université de Montréal, Montréal, Québec, Canada. rechcalcium.chum@ssss.gouv.qc.caAbstractPURPOSE OF REVIEW: Carboxyl-terminal parathyroid hormone (C-PTH) fragments constitute 80% of circulating PTH. Since the first 34 amino acids of the PTH structure are sufficient to explain PTH classical biological effects on the type I PTH/PTHrP receptor and since C-PTH fragments do not bind to this receptor, they have long been considered inactive. Recent data suggest the existence of a C-PTH receptor through which C-PTH fragments exert biological effects opposite to those of human PTH(1-84) on the type I PTH/PTHrP receptor. This is why a lot of attention has been paid to these fragments recently.
