Abstract
Background: Sclerostin, a protein encoded by the SOST gene, is an important genetic risk factor for osteoporosis in postmenopausal women. This study was conducted on the Iranian postmenopausal women, to investigate the association between this gene and the Trabecular Bone Score (TBS) as a novel index used for assessing osteoporosis.
Methods: The present study, conducted in 2024, was performed on 1071 women aged 60 years and older who participated in the Bushehr Elderly Health (BEH) program. The associations between seven independent Single Nucleotide Polymorphisms (SNPs) within the SOST gene and mean TBS of L1 to L4 were examined using the additive, dominant, and recessive models. Genetic risk scores (GRS) were calculated for each postmenopausal woman based on the coefficient regressions derived from the additive and dominant models. The relationship between the GRS quartiles and TBS was evaluated using a linear regression model.
Results: After adjusting for age and Body Mass Index (BMI), the associations between the rs2023794-C and TBS were significant in the additive (β = 0.03, P= 4.7×10-5, PFDR= 0.0003) and dominant (β = 0.032, P= 5×10-5, PFDR= 0.0003) models. The GRS derived from both additive and dominant models were related to TBS (P<0.05). For the additive model GRS, TBS showed an average increase of 0.022 score for the fourth quartile in comparison with the first quartile, adjusted for age, BMI, type 2 diabetes mellitus (T2DM), and smoking status (P=0.001).
Conclusion: SOST gene is associated with TBS and may have implications for personalized medicine. Targeting sclerostin through SOST could offer a therapeutic approach in managing osteoporosis in high-risk postmenopausal women.
期刊介绍：
Iranian Journal of Public Health has been continuously published since 1971, as the only Journal in all health domains, with wide distribution (including WHO in Geneva and Cairo) in two languages (English and Persian). From 2001 issue, the Journal is published only in English language. During the last 41 years more than 2000 scientific research papers, results of health activities, surveys and services, have been published in this Journal. To meet the increasing demand of respected researchers, as of January 2012, the Journal is published monthly. I wish this will assist to promote the level of global knowledge. The main topics that the Journal would welcome are: Bioethics, Disaster and Health, Entomology, Epidemiology, Health and Environment, Health Economics, Health Services, Immunology, Medical Genetics, Mental Health, Microbiology, Nutrition and Food Safety, Occupational Health, Oral Health. We would be very delighted to receive your Original papers, Review Articles, Short communications, Case reports and Scientific Letters to the Editor on the above mentioned research areas.
