Osteoprotegerin (OPG) plays an important inhibitory role in osteoclastogenesis. Polymorphisms in the OPG gene recently have been associated with various bone phenotypes including fractures. The aim of the present study was to investigate the association between three informative OPG polymorphisms and quantitative ultrasound variables of the heel. In a cohort of 165 perimenopausal women polymorphisms in the OPG promoter (A163G, T245G) and in exon 1 (G1181C) were assessed by PCR-RFLP analysis. The distribution of the investigated genotypes was similar to other Caucasian women (A163G-AA 68 %, AG 30 %, GG 2 %, T245G-TT 84.4 %, TG 15 %, GG 0.6 %, G1181C- GG 22 %, CG 55 %, CC 23 %). After adjustment for body mass index and years since menopause, in a subgroup of 87 postmenopausal subjects, calcaneal velocity of sound (VOS, m/s) was significantly associated with A163G polymorphism (p=0.0102, ANCOVA). Women with the presence of G allele (AG+GG genotypes) had significantly lower VOS than women with AA genotype. Neither T245G nor G1181C were associated with calcaneal ultrasound indices. In conclusion, A163G polymorphism was significantly associated with VOS at the heel in a limited cohort of postmenopausal women. The present study replicated in part the previous findings about OPG gene variations and peripheral bone mass in Caucasian women.

Objectives: The present study investigated osteoprotegerin (OPG) genetic polymorphisms and their influence on the therapeutic response to ibandronate in postmenopausal osteoporotic females.
Methods: This case-control study included 135 postmenopausal females (89 osteoporotic females and 46 non-osteoporotic females). Each osteoporotic patient received a monthly 150 mg ibandronate tablet for six months, and blood samples were taken before and after treatment.

Background: A large proportion of pulmonary embolism (PE) heritability remains unexplained, particularly among the East Asian (EAS) population. Our study aims to expand the genetic architecture of PE and reveal more genetic determinants in Han Chinese.
Methods: We conducted the first genome-wide association study (GWAS) of PE in Han Chinese, then performed the GWAS meta-analysis based on the discovery and replication stages.

Numerous studies have demonstrated an association between osteoprotegerin () polymorphisms (A163G (rs3102735), T245G (rs3134069), T950C (rs2073617), G1181C (rs2073618)) and osteoporosis risk. However, their conclusions are inconsistent. In addition, some new studies have been updated, and more importantly, previous meta-analyses have not tested for false-positive results.

Background: Subjects with low bone mineral density and osteoporosis are more likely to suffer osteoporotic fractures during their lifetime. Polymorphisms in osteoprotegerin (OPG) gene are found to be associated with low bone mineral density and osteoporosis risk but their association with fracture risk is inconclusive. Here, we performed a meta-analysis to investigate the relationship between OPG polymorphisms with susceptibility to osteoporotic fractures.

Background: AT1R (Angiotensin II type 1 receptor) is the main component of RAS (renin-angiotensin system) system, which activates when ANG II (angiotensin II) binds to it. AT1R helps in maintaining osmotic homeostasis and blood pressure regulation. A huge number of polymorphism are associated with AT1R and few of them were studied and found to be associated with the diseases and drug efficacy.
