Abstract
|
|
|
|
Vascular endothelial growth factor (VEGF) is involved in bone formation through its role in angiogenesis. VEGF is also known to promote the healing of fractures. Thus, we determined whether or not VEGF ?2578C>A, ?1154G>A, ?634G>C, and 936C>T polymorphisms and haplotypes are associated with osteoporotic vertebral compression fractures (OVCF) in postmenopausal Korean women. The study subjects consisted of 82 patients with osteoporotic vertebral compression fractures and 117 control postmenopausal Korean women. PCR-RFLP and real-time PCR were used to analyze the VEGF polymorphisms. Homocysteine levels were also measured to determine whether or not polymorphisms of the VEGFgene affect homocysteine/folate metabolism. The AA genotype of the ?2578C>A polymorphism was significantly different between the stroke and control groups; no significant differences in the ?1154G>A, ?634G>C, and 936C>T genotype frequencies existed. However, the A-G-G-C haplotype had a tendency to be associated with OVCF in postmenopausal Korean women. Associations between the VEGF ?2578C>A polymorphism and homocysteine levels were also noted. In summary, these results suggest that the VEGF ?2578C>A polymorphisms and VEGF haplotypes may play an important role in the etiology of OVCF in postmenopausal Korean women.
