[Research progress of bone morphogenetic protein and liability of ossification of posterior longitudinal ligament].

OBJECTIVE

To review the research progress of bone morphogenetic protein (BMP) and the liability of ossification of the posterior longitudinal ligament (OPLL).

METHODS

Recent literature concerning BMP and the liability of OPLL was reviewed, analysed, and summarized.

RESULTS

The single nucleotide polymorphisms (SNPs) of BMP gene may produce a minor cumulative effect and increase individual susceptibility to OPLL. A variety of environmental factors can promote the occurrence and development of OPLL by increasing the expression of BMP gene.

CONCLUSION

The SNPs of BMP gene may increase individual susceptibility to OPLL. However, interaction of cumulative effect of the SNPs and environmental factors can promote the liability to OPLL.
