CCL2/Monocyte Chemoattractant Protein 1 and Parathyroid Hormone Action on Bone
Chemokines are small molecules that play a crucial role as chemoattractants for several cell types, and their components are associated with host immune responses and repair mechanisms. Chemokines selectively recruit monocytes, neutrophils, and lymphocytes and induce chemotaxis through the activation of G protein-coupled receptors. Two well-described chemokine families (CXC and CC) are known to...
متن کاملUnderstanding parathyroid hormone action.
In addition to regulating serum calcium and stimulating bone resorption, parathyroid hormone (PTH) is known to stimulate bone formation under certain conditions. The mechanisms behind this counterintuitive anabolic action are largely unknown. We have set out to identify PTH-regulated genes that might be responsible for each of these contrasting effects of the hormone. This article describes our...
متن کاملParathyroid hormone bone anabolic action requires Cbfa1/Runx2-dependent signaling.
The Cbfa1/Runx2 (referred to herein as Cbfa1) transcription factor has been shown to be essential for osteoblast differentiation and bone formation during embryogenesis. PTH given intermittently is a proven bone anabolic agent. Here, we investigated whether PTH regulates the expression and/or activity of Cbfa1 in osteoblastic cells and in a rat metatarsal organ culture assay. PTH was found to r...
متن کاملParathyroid hormone 1-34 and skeletal anabolic action
Intermittently administered parathyroid hormone (PTH 1-34) has been shown to promote bone formation in both human and animal studies. The hormone and its analogues stimulate both bone formation and resorption, and as such at low doses are now in clinical use for the treatment of severe osteoporosis. By varying the duration of exposure, parathyroid hormone can modulate genes leading to increased...
متن کاملHypotensive action of parathyroid hormone preparations on rats and dogs.
Bovine parathyroid extract and two commercial preparations containing the first 34 amino acids of synthetic bovine parathyroid hormone [bPTH-(1-34)]produced dose-related hypotension in anesthetized rats. Dogs were 10 times more sensitive to the two bPTH-(1-34) preparations than were rats. Propranolol, phentolamine, atropine, and promethazine did not affect the hypotensive action of bPTH-(1-34) ...
