Vitamin D status affects serum parathyroid hormone concentrations during winter in female adolescents: associations with forearm bone mineral density
25-hydroxyvitamin D adolescent females bone mineral density
2016/6/14
Vitamin D deficiency leads to secondary hyperparathyroidism,
which has a negative effect on bone metabolism
in the elderly. Puberty is an important time of bone metabolism
and growth. The effect of...
Parathyroid Hormone Enhances Mechanically Induced Bone Formation, Possibly Involving L-Type Voltage- Sensitive Calcium Channels
parathyroid hormone bone formation
2014/12/4
PTH and mechanical loading might act synergistically on bone formation. We tested the in vivo effect of the L-type voltage-sensitive calcium channel (VSCC) blocker, verapamil, on bone formation induce...
Nmp4/CIZ suppresses the response of bone to anabolic parathyroid hormone by regulating both osteoblasts and osteoclasts
c-fos Fra-2 osteoclastogenesis
2014/11/6
How parathyroid hormone (PTH) increases bone mass is unclear, but understanding this phenomenon is significant to the improvement of osteoporosis therapy. Nmp4/CIZ is a nucleocytoplasmic shuttling tra...
Nmp4 restricts bone marrow osteoprogenitors and parathyroid hormone induced bone formation in healthy and estrogen depleted female mice
Osteoprogenitor Estrogen depletion
2015/5/21
We have shown that nuclear matrix protein 4 (Nmp4) attenuates the response to intermittent parathyroid hormone (PTH) in healthy and ovariectomized (OVX) female mice using a global knockout of the Nmp4...
Variability of Serum Concentration of Calcium, Phosphate and Parathyroid Hormone Depending on Time of Blood Draw for Patients on Nocturnal Home Hemodialysis
Nocturnal Hemodialysis Calcium Phosphate Parathyroid Hormone
2013/1/31
Background: Guidelines for patients treated with conventional hemodialysis patients have been written for target serum levels for calcium (Ca), phosphate (PO4) and intact parathyroid hormone (iPTH). N...
Rat wild-type parathyroid hormone receptor（PTH-R）and mutant PTH-RP132L show the different intracellular localization in vitro
Rat wild-type parathyroid hormone receptor（PTH-R） mutant PTH-RP132L
2009/3/2
A replacement of proline with leucine at position 132 of the receptor for parathyroid hormone (PTH)/parathyroid hormone-related peptide (PTHrP), i.e., PTH-R, has been discovered in human Blomstrand'...
Immunoreactive parathyroid hormone-related protein is present in human seminal plasma and is of prostate origin
Immunoreactive parathyroid hormone-related protein human seminal plasma
2009/2/12
Parathyroid hormone-related protein (PTHrP) is a regulatory peptide that has been associated with normal fetal growth and differentiation as well as the regulation of fetal calcium. We recently d...
Association of low 25-hydroxyvitamin D concentrations with elevated parathyroid hormone concentrations and low cortical bone density in early pubertal and prepubertal Finnish girls
cortical bone density biomarkers prepubertal girls
2017/1/4
We studied the associations of serum 25(OH)D and intact PTH (iPTH) with bone mineral content (BMC) and bone mineral density (BMD) at different bone sites and the relation between serum 25(OH)D and iPT...
A threshold for low-protein-diet–induced elevations in parathyroid hormone
Dietary protein calcium metabolism calcitropic hormones vitamin D parathyroid hormone
2016/6/7
Background: We reported previously that lowering dietary protein
intake in young healthy women to 0.7 g/kg depressed intestinal calcium
absorption and was accompanied by elevations in parathyroid
h...
Vitamin D status: effects on parathyroid hormone and 1,25-dihydroxyvitamin D in postmenopausal women
Aging 25-hydroxyvitamin D 25(OH)D, 1,25-dihydroxyvitamin D 1,25(OH)2D parathyroid hormone, postmenopausal women
2016/6/7
Background: Low serum 25-hydroxyvitamin D [25(OH)D] concentrations
are commonly found in the elderly and are associated
with hip fracture. Treatment with vitamin D and calcium can
reduce the risk o...
Altered diurnal regulation of blood ionized calcium and serum parathyroid hormone concentrations during parenteral nutrition
Parathyroid hormone total parenteral nutrition, TPN metabolic bone disease hyperparathyroidism diurnal variation adults bone biopsy blood ionized calcium
2016/6/3
Background: Little is known about parathyroid gland function
in patients receiving total parenteral nutrition (TPN).
Objective: Our objective was to determine whether parathyroid
gland function is ...
