Sk. Abbas et al., THE ROLE OF PARATHYROID HORMONE-RELATED PROTEIN IN CALCIUM HOMEOSTASIS IN THE FETAL PIG, Experimental physiology, 79(4), 1994, pp. 527-536
The concentrations of plasma parathyroid hormone-like bioactivity and
parathyroid hormone-related protein (1-86) (PTHrP) immunoreactivity we
re both higher in fetal pigs than in their mothers during the last 3 w
eeks of gestation. Both activities changed inversely with alterations
in the plasma ionized calcium concentration. The data suggest that PTH
rP may have a role in calcium homeostasis in the fetal pig, similar to
its postulated role in sheep in the stimulation of calcium transport
across the placenta.
