Study of Hyp or Phex null male fetuses reveals that eightfold increased FGF23 does not alter fetal–placental phosphorus homeostasis or prenatal bone formation and mineralization

Ma Yue , Kirby Beth J. , Kovacs Christopher S.

Fibroblast growth factor-23 (FGF23) controls serum phosphorus by acting on the kidneys to excrete phosphorus and reduce calcitriol. These actions are well established in adults and children, but whether FGF23 regulates fetal phosphorus metabolism is unknown. We used X-linked Hyp or Phex null male fetuses to study the effect of excess FGF23 on fetal phosphorus metabolism. Phex+/− females and WT males were mated to generate WT, Phe...

Trabecular (Spine) bone density increases significantly in the first 6 months after weaning (Factors Affecting Bone Formation After Breastfeeding Pilot Study (FABB-Pilot))

Breastfeeding women resorb trabecular bone to supply much of the calcium content of milk. Few studies have examined the speed and extent of BMD recovery after weaning, or the factors that predict a greater post-lactation increase in BMD. We hypothesize that weight-bearing, nutrition, hormones, and other factors facilitate bone formation after lactation.The aims of the Factors Affecting Bone Formation After Breastfeeding Pilot Study (FABB-Pilot) were to d...
