Osteopontin deficiency induces parathyroid hormone enhancement of cortical bone formation.
Intermittent PTH treatment increases cancellous bone mass in osteoporosis patients; however, it reveals diverse effects on cortical bone mass. Underlying molecular mechanisms for anabolic PTH actions are largely unknown. Because PTH regulates expression of osteopontin (OPN) in osteoblasts, OPN could be one of the targets of PTH in bone. Therefore, we examined the role of OPN in the PTH actions ...
متن کاملParathyroid hormone without parathyroid glands.
In mammals, PTH is a component in a complex signaling system involving three structurally related ligands and two G protein-coupled receptors, which share significant amino acid sequence homology (Fig. 1). PTH is a peptide hormone comprising 84 amino acids that is made by the parathyroid glands (and to a much smaller extend by the thymus) and acts through the PTH/PTH-related peptide (PTHrP) rec...
متن کاملImpact of proteoglycan-4 and parathyroid hormone on articular cartilage.
Proteoglycan-4 (Prg4) protects synovial joints from arthropathic changes by mechanisms that are incompletely understood. Parathyroid hormone (PTH), known for its anabolic actions in bone, increases Prg4 expression and has been reported to inhibit articular cartilage degeneration in arthropathic joints. To investigate the effect of Prg4 and PTH on articular cartilage, 16-week-old Prg4 mutant and...
متن کاملPTHLH (parathyroid hormone-like hormone)
DNA/RNA Description PTHLP is encoded by a single gene that is highly conserved among species. The gene is composed of 7 exons spanning a region of 13,899 bases (Start: 28,002,284 bp from pter; End: 28,016,183 bp from pter). Orientation: minus strand. The genomic DNA for the PTHLP gene was isolated from a human placental genomic library. Transcription The sequence is supported by 3 sequences fro...
متن کاملAbnormalities in hepatic lipase in chronic renal failure: role of excess parathyroid hormone.
Post-heparin hepatic lipase activity is reduced in chronic renal failure (CRF). This could be due to reduced synthesis, decreased activity, and/or impaired secretion of the enzyme. Further, the factor(s) responsible for such derangements are not elucidated. We examined hepatic lipase metabolism in normal, 6-wk-old CRF rats, CRF-PTX (parathyroidectomized) rats, and CRF and normal rats treated wi...
