The P2Y2 receptor restrains BMD during development

Syberg Susanne , Ellegaard Maria , Schwarz Peter , Jorgensen Niklas Rye

The P2Y2 receptor is a G-protein-coupled receptor and the natural ligands (ATP/UTP) strongly inhibit mineralized bone nodule formation by osteoblasts in vitro. We have earlier shown that overexpression of the P2Y2 receptor in vivo resulted in decreased bone mineral density (BMD), partially due to increased bone resorption, but also decreased formation (detected by serum bone markers and bone histomorphometry).This ...

Prolonged botulinum toxin type A-induced muscle paralysis results in loss of bone mineral density and bone strength in young female rats

Ellegaard Maria , Syberg Susanne , Jorgensen Niklas Rye , Schwarz Peter

Transient paralysis by a single injection of botulinum toxin type A (Botox) in rodents has been shown to cause local bone loss of the affected leg. The animals regain function of the leg within 3–4 weeks and bone loss slowly recovers. The duration of the paralysis is dose-dependent. However, higher doses of Botox cause weight loss and decreased activity level.Aim of study was to investigate whether repeated injections of low-dose Botox could induce ...
