We previously demonstrated that an isocaloric low protein diet attenuates the bone anabolic response to GH. Whether such a dietary manipulation could affect the bone anabolic effects of PTH was assessed. We studied 6-month-old female rats pair fed with isocaloric diets with a low protein (2.5% casein, LP) or normal protein content (15% casein, NP) for 2 weeks. Then, the animals were treated with 5 or 40 μg/kg recombinant human amino-terminal fragment PTH(1–34) (PTH-5...
