Spinal malformation - A biochemical analysis using congenital kyphosis rats.

Spinal kyphosis involves the vertebrae curving excessively backward, beyond their physiological curvature. Although the normal structure of the spinal vertebrae is extremely important for maintaining posture, the normal function of the thoracic and abdominal organs, and cosmetics, our knowledge concerning the pathogenesis of this disease is lacking. Furthermore, the responsible gene has not yet been identified. In this short review, we summarize the current state of kyphosis research and introduce the molecular and cellular mechanisms associated with the pathogenesis of this disease, based on findings obtained using rats that develop kyphosis.
