Abstract


OBJECTIVES
To investigate the relationship between single nucleotide polymorphisms (SNPs) in leptin and adrenergic receptors genes, and the production of osteoprotegerin (OPG) and soluble receptor activator of NF-kappaB ligand (sRANKL) by whole blood cells (WBC) after hormone therapy (HT) in postmenopausal Korean women.
METHODS
The leptin receptor c.326A>G, c.668A>G, c.1968G>C SNPs, beta2 adrenergic receptor c.46A>G, c.79C>G SNPs, and beta3 adrenergic receptor c.190T>C SNP were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and Taqman assay in postmenopausal Korean women. The production of OPG and sRANKL by lipopolysaccharide (LPS)-stimulated WBC before (n=149) and after (n=73) estrogen-progestogen therapy of 6 months were also measured.
RESULTS
At baseline, the production of OPG and sRANKL by LPS-stimulated WBC, and in ratios of sRANKLx1,000/OPG were not different according to leptin and beta2 adrenergic receptors genetic polymorphisms, but the TT genotype of beta3 adrenergic receptor c.190T>C SNP showed significantly lower OPG production than non-TT genotype. Among SNPs measured, the beta2 adrenergic receptor c.46A>G SNP only was related with changes in the production of sRANKL by WBC after HT of 6 months. The production of sRANKL by WBC after HT decreased significantly in AA genotype of beta2 adrenergic receptor c.46A>G SNP, compared to other genotypes.
CONCLUSION
The beta3 adrenergic receptor c.190T>C SNP is related with the production of OPG by WBCs before HT, whereas the beta2 adrenergic receptor c.46A>G SNP affects the changes in the production of sRANKL by WBCs after HT.
