PTH-related peptide (PTHrP) in hypercalcemia.
It is now 20 years since the tumor-associated factor parathyroid hormone-related peptide was identified. Since then, there have been significant changes in the understanding of the hypercalcemic syndromes associated with malignancy and with the role of this peptide in normal physiology as well as this specialized pathologic setting. Parathyroid hormone-related peptide has become a useful diagno...
متن کاملParathyroid hormone-related peptide (PTHrP) induces parietal endoderm formation exclusively via the Type I PTH/PTHrP receptor
A number of studies suggest a role for PTHrP and the classical PTH/PTHrP receptor (type I) in one of the first differentiation processes in mouse embryogenesis, i.e. the formation of parietal endoderm (PE). We previously reported that although in type I receptor (-/-) embryos PE formation seemed normal, the embryos were smaller from at least day 9.5 p.c. and 60% had died before day 12.5 p.c. He...
متن کاملApoptosis mediated by activation of the G protein-coupled receptor for parathyroid hormone (PTH)/PTH-related protein (PTHrP).
The present studies were carried out to evaluate the mechanisms by which PTH/PTHrP receptor (PTHR) activation influences cell viability. In 293 cells expressing recombinant PTHRs, PTH treatment markedly reduced the number of viable cells. This effect was associated with a marked apoptotic response including DNA fragmentation and the appearance of apoptotic nuclei. Similar effects were evidenced...
متن کاملDevelopmental upregulation of human parathyroid hormone (PTH)/PTH-related peptide receptor gene expression from conserved and human-specific promoters.
The parathyroid hormone (PTH)/PTH-related peptide (PTHrP) receptor (PTHR) functions in skeletal development and mediates an array of other physiological responses modulated by PTH and PTHrP. PTHR gene transcription in mouse is controlled by two promoters: P1, which is highly and selectively active in kidney; and P2, which functions in a variety of tissues. P1 and P2 are conserved in human tissu...
متن کاملTargeted expression of constitutively active receptors for parathyroid hormone and parathyroid hormone-related peptide delays endochondral bone formation and rescues mice that lack parathyroid hormone-related peptide.
Mice in which the genes encoding the parathyroid hormone (PTH)-related peptide (PTHrP) or the PTH/PTHrP receptor have been ablated by homologous recombination show skeletal dysplasia due to accelerated endochondral bone formation, and die at birth or in utero, respectively. Skeletal abnormalities due to decelerated chondrocyte maturation are observed in transgenic mice where PTHrP expression is...
