Implication

Animal study demonstrates that chronic warfarin exposure induces premature growth plate fusion and stops bone growth in rats, suggesting bone Gla protein prevents excessive mineralization.

Key Points

To assess the skeletal effects of chronic warfarin-induced depletion of bone Gla protein on bone growth and mineralization.
Maintained rats on a continuous warfarin regimen for 8 months at a dosage sufficient to lower bone Gla protein to 2% of normal levels.
Warfarin-treated rats developed an excessive mineralization disorder characterized by complete closure and fusion of the proximal tibial growth plate, resulting in total cessation of longitudinal bone growth.
The pathological features in rats closely mirror human fetal warfarin syndrome, implicating the loss of mineralization inhibition normally provided by bone Gla protein.
