Our knowledge of the developmental changes in the concentration of serum and bone osteocalcin (OC) is limited. To investigate the inter...
Mouse genetic model for bone strength and size phenotypes: NZB/B1NJ and RF/J inbred strains
The relationships of bone size, bone strength, and bone formation were investigated in two strains of mice, NZB/B1NJ and RF/J. Measurem...
High bone resorption in adult aging transgenic mice overexpressing cbfa1/runx2 in cells of the osteoblastic lineage
The runt family transcription factor core-binding factor alpha1 (Cbfa1) is essential for bone formation during development. Surprisingl...
Common herbs, essential oils, and monoterpenes potently modulate bone metabolism
During our survey of herbs looking for activity on bone metabolism, we found that the dried leaves of sage strongly inhibit bone resorp...
In vivo rat assay: bone remodeling and steroid effects on juvenile bone by pQCT quantification in 7 days
Anesthetized Sprague-Dawley weanling rats were scanned for bone mineral density (BMD) values after 7 days of treatment to determine whe...
Peripheral quantitative computed tomography for the detection of diabetic osteopathy: a study in the Goto-Kakizaki rat
RATIONALE AND OBJECTIVE: To assess the utility of dual energy x-ray absorptiometry (DEXA) and peripheral quantitative computed tomograp...
Evidence that anabolic effects of PTH on bone require IGF-I in growing mice
Although it has been established that PTH exerts potent anabolic effects on bone in animals and humans, the mechanism of PTH action on ...
Ablation of TRalpha2 and a concomitant overexpression of alpha1 yields a mixed hypo- and hyperthyroid phenotype in mice
Thyroid hormone governs a diverse repertoire of physiological functions through receptors encoded in the receptor genes alpha and beta,...
Rodent model for investigating the effects of estrogen on bone and muscle relationship during growth
It has been reported that in humans from about 11-12 years of age, bone mass begins to increase faster in girls than in boys with the s...
Insulin-like growth factor-binding protein-2 (IGFBP-2) overexpression negatively regulates bone size and mass, but not density, in the absence and presence of growth hormone/IGF-I excess in transgenic mice
Insulin-like growth factor-binding protein-2 (IGFBP-2) has been suggested to be a negative regulator of bone growth and maintenance. Th...
