Abstract
PDF - Background
Estrogen status is important for maintaining the homeostasis of bone. Estrogen has direct effects on bone cells, through binding to the high-affinity estrogen receptor. Several recent studies suggest that there might be genetically determined variations in biosynthesis and function of estrogen receptor in postmenopausal osteoporosis. Also the main cause of postmenopausal osteoporosis is decreased level of serum estrogen, whereas there had been some suggestion that the remaining estrogen have some effect on bone metabolism after menopause. We investigated the relationship between estrogen receptor gene PvulI polymorphism and bone mineral density(BMD), and the relationship between 18 urinary metabolites of estrogen and BMD in Korean postmeno- pausal osteoporosis. Methods: We examined the PvuII polymorphism of the estrogen receptor gene in 5' upstream region and the first intron by restrietion frapnent length polymorphism analysis in 62 postmeno- pausal wornen, BMD was measured by DEXA. The urinary estrogen metabolites were determined by GC/MS(Gas Chromatography-Mass Spectrometry) at Korean Institute of Science and Techno- logy Doping Control Center. Results: BMD of the spine and the femoral neck correlated with body weight, height, body mass index as we expected. There was no polymorphism of PvuII restriction site on 5 upstream region of estrogen receptor gene. Whereas the prevalen~ee of the PP, Pp, pp genotype in the first intron of estrogen receptor was 12.9%, 45.2%, 41.9%, respectively. But, there was no correlation between PvuII genotype and the spinel and femoral neck BMD. 2(OH)E2 among 18 urinary metabolites of estrogen, showed a negative correlation with the spinal and femoral neck BMD(r =-0.2551, p<0.05, and r =-0.3341, p<0.01, respectively), and the ratio of 16a(OH)E2/2(OH)E1> revealed a positive correlation with the spinal BMD(r =0.3057, p<0.05). In stepwise multiple regression analysis, body weight, 2(OH)E2, 16a(OH)E1, 2(Meo)E1 were independent predictors of the spinal bone density, and body weight and 2(OH)E2 were independent predictors of the femoral neck bone density. Conclusion: These results suggested that restrietion fragment length polymorphism analysis of the estrogen receptor gene with PvuII restriction enzyme was not helpful for early detection of patients at risk of developing osteoporosis. However, the ratio of 16-hydroxylation to 2-hydroxylation of estrogen metabolism was reduced in postmenopausal women and high catecholestrogen formation might be a greater risk factor for osteoporosis.

ePub Background Despite the beneficial effect of fibroblast growth factor 21 (FGF21) on metabolic disease, there are concerns about adverse effects on bone metabolism, supported by animal studies. However, a recent human study showed the positive association between serum FGF21 level and bone mineral density (BMD) in healthy premenopausal women. We undertook this study to examine the association between FGF21 level and BMD in healthy postmenopausal Korean women who are susceptible to osteoporosis.
Methods We used data of 115 participants from a cohort of healthy postmenopausal women (>50 years old) to examine the association between serum FGF21 level and BMD. The clinical characteristics were obtained from the participants, and blood testing and serum FGF21 testing were undertaken. BMD of the lumbar spine, femoral neck and total hip area, and bone markers were used in the analyses.
Results The mean age of the participants was 60.2±7.2 years. Serum FGF21 levels showed negative correlation with BMD and T-scores in all three areas, but there were no statistically significant differences. Multivariate analyses with adjustment for age and body mass index also did not show significant association between serum FGF21 level and BMD. In addition, serum FGF21 level also showed no correlation with osteocalcin and C-telopeptide levels.
Conclusion In our study, serum FGF21 level showed no significant correlation with BMD and T-scores.

Supplementary MaterialPubReader Background Multipotent mesenchymal stem cells can differentiate into adipocytes or osteoblasts through closely regulated lineage-control processes. However, adipocyte precursor cells release preadipocyte factor 1 (Pref-1), which inhibits the differentiation of mesenchymal stem cells into mature adipocytes and osteoblasts. Previous studies have also reported an inverse association between Pref-1 levels and bone mineral density (BMD) among patients with anorexia nervosa.
Methods In this retrospective study, we examined the correlations between Pref-1 levels and BMD among 124 healthy postmenopausal women (>50 years old). The patients had provided information regarding their clinical characteristics, and underwent blood testing and serum Pref-1 testing.
Results The subjects' mean age was 59.9±7.1 years and the median time since menopause onset was 9.1 years. A history of osteoporotic fracture was identified in 23 subjects (19%). Serum Pref-1 levels were not significantly correlated with BMD values at the lumbar spine (
R 2=0.038,P =0.109), femur neck (R 2=0.017,P =0.869), and total hip (R 2=0.041,P =0.09), and multivariate analyses with adjustment for age and body mass index also did not detect any significant correlations. Subgroup analyses according to a history of fracture also did not detect significant associations between Pref-1 levels and BMD values.Conclusion In our study population, it does not appear that serum Pref-1 levels are significantly associated with BMD values and osteoporosis.
