Parathyroid hormone and bone mobilization in vitro.
نویسندگان
چکیده
A two-phase system in vitro has been developed for studying the bone-mobilizing effects of parathyroid hormone. Phase I consists of the incubation of hormone with ascites cells, and Phase II is the incubation of Phase I supernatant with dead bone powder. The mobilization of labeled calcium from this powder is the index of hormonal activity. The response to hormone is apparent at lo-* M hormone, appears specific for parathyroid hormone, and has striking analogies to hormone action upon living bone in vivo and in vitro.

متن کاملParathyroid Hormone-Related Peptide and Vitamin D in Phosphocalcic Metabolism for Dromedary Camel
In mammals, phosphocalcic and bone metabolisms are mainly regulated by parathyroid hormone, parathyroid hormone-related peptide (PTHrP) and 1α,25-dihydroxyvitamin D or calcitriol. In camels, circulating levels of calcitriol are 10 times higher than those determined in other ruminants and further increase during early lactation. Calcitriol and parathyroid-related peptide stimulate intestinal abs...
متن کاملEffects of Oral Isotretinoin on Serum Vitamin D Metabolites and Other Biochemical Markers of Bone Turnover and Calcium Homeostasis in Severe Acne
Background: Few studies have investigated on vitamin D metabolites Serum levels, and calcium homeostasis in humans receiving retinoids, despite a substantial amount of literature concerning retinoid-induced osteoporosis in animals. We prospectively measured vitamin D metabolites serum levels and calcium homeostasis and radiographic bone changes in short course treatment with oral isotreti...
متن کاملMiR-125b inhibits stromal cell proliferation in giant cell tumor of bone by targeting parathyroid hormone 1 receptor
Objective(s):miR-125b has been identified as a tumor suppressor in many tumors, but its role in giant cell tumor (GCT) of bone remains poorly understood. The current study aimed to investigate the potential role and mechanism of miR-125b in GCT. Materials and Methods:Expression levels of miR-125b in GCT tissues were determined using RT-PCR. The cell proliferation was surveyed by direct cell coun...
متن کاملHuge Parathyroid Adenoma with Dysphagia Presentation; A Case Report from Southern Iran
AbstractParathyroid adenoma is a benign tumor of the parathyroid glands. The cause of most parathyroid adenomas is unknown. Parathyroid adenoma increases the secretion of parathyroid hormone and results in primary hyperparathyroidism. High amounts of parathyroid hormone in the blood cause the imbalance of calcium, which leads to various complications such as kidney stones, depression, lethargy,...
