Thymus-associated parathyroid hormone has two cellular origins with distinct endocrine and immunological functions. [PDF]

PLoS Genetics, 2010
In mammals, parathyroid hormone (PTH) is a key regulator of extracellular calcium and inorganic phosphorus homeostasis. Although the parathyroid glands were thought to be the only source of PTH, extra-parathyroid PTH production in the thymus, which ...

Origin of parathyroid hormone (PTH) fragments detected by intact-PTH assays [PDF]

European Journal of Endocrinology, 2002
BACKGROUND: Intact parathyroid hormone (I-PTH) assays react with non-(1-84)PTH, large carboxyl-terminal (C) fragments with a partially preserved amino-terminal (N) structure. They account for up to 50% of I-PTH in renal failure and may be implicated in PTH resistance.

Parathyroid localization [PDF]

, 1986
Twenty-nine consecutive patients with suspected primary hyperparathyroidism were examined preoperatively using ultrasound, sonographically guided fine needle aspiration, and aspirate immunostaining for PTH.

Diagnostic approach to hypercalcemia: relevance of parathyroid hormone and parathyroid hormone-related protein measurements [PDF]

, 2001
Background: Parathyroid hormone (PTH) and parathyroid hormone-related protein (PTH-rP) are two potent hypercalcemic hormones that act on the same targets.

Older Age Is Associated with Decreased Levels of VDR, CYP27B1, and CYP24A1 and Increased Levels of PTH in Human Parathyroid Glands

International Journal of Endocrinology, 2020
Parathyroid glands contain the vitamin D receptor (VDR) and 25-hydroxyvitamin D-1α-hydroxylase (CYP27B1) and 24-hydroxylase (CYP24A1), which catalyze the production and degradation of 1,25-dihydroxyvitamin D [1,25(OH)2D], respectively.

Parathyroid hormone as early marker of derangements of mineral metabolism among patients in various stages of chronic kidney disease [PDF]

Al Ameen Journal of Medical Sciences, 2023
Background: Chronic Kidney Disease (CKD) is an international public health problem affecting about 5-10% of the population. As kidney function declines, there is a progressive deterioration in mineral homeostasis with disruption of normal serum ...

Disparity between Preoperative and Pre-Excisional Intraoperative Parathyroid Hormone in Parathyroid Surgery

International Archives of Otorhinolaryngology, 2018
Introduction Intraoperative parathyroid hormone (ioPTH) testing is a widely accepted standard for assessing the parathyroid gland function. A decline of preoperative parathyroid hormone (PTH) levels by more than 50% is one accepted measure of parathyroid

Secretion of parathyroid hormone may be coupled to insulin secretion in humans

Endocrine Connections, 2020
Objective: Parathyroid hormone (PTH) is a key hormone in regulation of calcium homeostasis and its secretion is regulated by calcium. Secretion of PTH is attenuated during intake of nutrients, but the underlying mechanism(s) are unknown.
