Relationship between glucagon-like peptide-1 receptor gene polymorphism and bone mineral density in postmenopausal women in Shanghai.

BACKGROUND Glucagon-like peptide-1 receptor (GLP-1R) agonists are able to inhibit bone resorption to a certain extent and improve bone formation. GLP-1R single nucleotide polymorphism (SNP) is related to its activity, but the relationship between GLP-1R SNP and osteoporosis in postmenopausal women was still unclear. This study was to investigate the association between GLP-1R SNP and bone mineral density (BMD) in postmenopausal women in Shanghai. METHODS Eight SNPs of GLP-1R were detected (rs3765467, rs1042044, rs2268657, rs6923761, rs2268641, rs2295006, rs4714210 and rs10305420) in 884 postmenopausal women in Shanghai. The correlation between GLP-1R SNP and BMD was further assessed. RESULTS The A/A genotype of rs2295006 was negatively related to lumbar vertebrae 1-4 BMD (P<0.05). Allele A was negatively related to hip BMD (P<0.05). There was a negative correlation between haplotype CGAGCCA and lumbar BMD, and a positive correlation between haplotype CGGGCTA and lumbar BMD. The remaining seven GLP-1R SNPs had no relationship with BMD. CONCLUSIONS The rs2295006 of GLP-1R is related to the BMD of postmenopausal women in Shanghai, China.
