Parathyroid hormone (PTH), PTH-derived peptides, and new PTH assays in renal osteodystrophy [PDF]

open access: yesKidney International, 2003
Parathyroid hormone (PTH), PTH-derived peptides, and new PTH assays in renal osteodystrophy. Reliable measurements of parathyroid hormone (PTH) concentrations in serum or plasma are critical for the appropriate diagnosis and management of patients with renal osteodystrophy.

PTH resistance

Molecular and Cellular Endocrinology, 2021
Parathyroid hormone (PTH), which is primarily regulated by extracellular calcium changes, controls calcium and phosphate homeostasis. Different diseases are derived from PTH deficiency (hypoparathyroidism), excess (hyperparathyroidism) and resistance (pseudohypoparathyroidism, PHP).

Improved assessment of bone turnover by the PTH-(1-84)/large C-PTH fragments ratio in ESRD patients [PDF]

open access: yesKidney International, 2001
Improved assessment of bone turnover by the PTH-(1-84)/large C-PTH fragments ratio in ESRD patients.BackgroundThe “intact” parathyroid hormone (PTH) assay recognizes PTH-(1-84) as well as amino terminally truncated PTH fragments, that is, large ...

High-Resolution Mass Spectrometry for the Measurement of PTH and PTH Fragments: Insights into PTH Physiology and Bioactivity

Journal of the American Society of Nephrology, 2022
Full-length parathyroid hormone (PTH 1–84) is crucial for the regulation of calcium and phosphate homeostasis and bone remodeling. PTH 1–84 is metabolized into various PTH fragments, which are measured with varying levels of efficiency by PTH immunoassays.

Effects of PTH and PTH Hypersecretion on Bone: a Clinical Perspective

Current Osteoporosis Reports, 2020
Hyperparathyroidism may be due to an autonomous hypersecretion of parathyroid hormone (PTH) or occurs in response to a number of physiological stimuli. A number of recent findings have provided new insights into the importance of the calcium-parathyroid-vitamin D axis to bone in normal physiology and pathological conditions.PTH is known to affect bone ...

PTH and PTH-Related Peptides

2015
Parathyroid hormone (PTH) is an 84-amino acid polypeptide endocrine hormone that is produced by the parathyroid glands and secreted into the circulation in response to low calcium levels.

[PTH].

Clinical calcium, 2005
Injectable forms of parathyroid hormone (PTH) and its N-terminal fragments are bone anabolic agents proven by randomized clinical trials. Alternate delivery forms of parathyroid hormone are under clinical or preclinical studies, including nasal, transdermal, and pulmonary formulations of PTH (1-34).

Parathyroid Hormone (PTH) Suppresses Rat PTH/PTH-Related Protein Receptor Gene Promoter

Biochemical and Biophysical Research Communications, 2001
Parathyroid hormone (PTH) regulates osteoblasts via a G protein-linked PTH/PTH-related protein (PTHrP) receptor. PTH effects on PTH/PTHrP receptor gene expression were studied in UMR 106 osteoblast-like cells. In heterogeneous nuclear RNA and Northern analysis, PTH suppressed PTH/PTHrP receptor transcription.

PTH Receptors and Skeletal Resistance to PTH Action

2020
Secondary hyperparathyroidism (SHPT) is an integral component of chronic kidney disease-mineral and bone disorder (CKD-MBD). Many factors have been associated with its development and progression, but the presence of skeletal or calcemic resistance to the action of PTH in CKD has often gone unnoticed.
