The bone status of male rats 6, 12, and 24 months of age (n = 10) was examined. Femur calcium (Ca), phosphorus (P), and osteocalcin contents; serum chemistry; and mechanical properties of the bone were measured and correlated. Diaphyseal Ca, P, and o

The human osteosarcoma cell line MG-63 has been used to study the production of the bone-specific protein, osteocalcin. In the absence of any stimuli, MG-63 cells secreted very low levels of osteocalcin. The secretion of osteocalcin started after a l

We have shown that ATP increases cytosolic Ca2+ in UMR-106 cells through P2-purinergic receptor stimulation (Calcif Tissue Int 45:251-254). This response was further characterized using cells loaded with indo-1/AM or prelabeled with [3H]inositol. ATP

We present evidence that the regulation of osteocalcin secretion by PTH and PGE2 in normal human bone cells can be produced in the human osteoblast-like cell line MG-63. Both cell cultures showed time- and dose-dependent stimulation of osteocalcin se

Administration of ovine-prolactin (O-PRL) stimulated Ca 2+ uptake in isolated duodenal cells prepared from vitamin D-deficient rats. The time course of this effect was biphasic: uptake activity reached a peak in 2.5 hrs followed by a decrease at 5 hr

The effect of dietary phosphorus on intestinal calcium uptake was examined in duodenal cells isolated from vitamin D-deficient chicks. Cells from chicks on a high phosphorus diet accumulated calcium at a rate 38% higher than cells from animals on a n

Previously we reported that uptake of Ca2+ in cells isolated from rat duodenum declined in senescence. In this paper we examined the possible mechanisms for this age-related defect. Duodenal vitamin D-dependent calcium-binding protein decreased stead

We confirmed our previous observation that duodenal Ca2+ absorption and serum 1,25-dihydroxyvitamin D (1,25-(OH)2D) levels declined concurrently in old (24 months old) rats as compared to young (6 months old) rats. It is well known that 1,25-dihydrox

Parathyroid hormone, when incubated with renal cells acting in vivo and in vitro, increased Na+/Ca2+ exchange activity. The effect of parathyroid hormone was specific for biologically active analogs and could be mimicked by cAMP and forskolin. Parath
