Association analysis; Bone mineral density; Osteoporosis; Osteoprotegerin gene; Postmenopausal women; Single nucleotide polymorphisms

Osteoporosis is an important and common complex health problem, particularly in postmenopausal women. It is characterized by a reduction in bone mineral density (BMD) and a deterioration of bone microarchitecture with a consequent increase of fracture risk. The osteoprotegerin (OPG) gene is considered to play an important role in the pathogenesis of osteoporosis. We analyzed SNPs ... more

Osteoporosis is a common multifactorial disease in postmenopausal women. This study aimed to investigate the association of the g.27563G>A osteoprotegerin (OPG) genetic polymorphism with bone mineral density (BMD) and osteoporosis. A case-control study was carried out with 435 osteoporosis postmenopausal women cases and 442 age-matched healthy controls. The BMD at the femoral ... more

We investigated associations between vitamin D receptor (VDR) gene polymorphisms, FokI T>C (rs2228570), BsmI G>A (rs1544410), ApaI G>T (rs7975232), and TaqI T>C (rs731236), with bone mineral density (BMD) in postmenopausal Mexican-Mestizo women. Three hundred and twenty postmenopausal women participated, who were classified ... more

Bone mineral density; Genetic variant; Osteoprotegerin gene; Primary osteoporosis; Risk factor

Primary osteoporosis is a common health problem in postmenopausal women. This study aimed to detect the association of the g.19074G>A genetic variant in the osteoprotegerin gene (OPG) with bone mineral density (BMD) and primary osteoporosis. The created restriction site-polymerase chain reaction method was used to investigate the g.19074G>A genetic variant. The BMD of the ... more

We investigated the effect of bone morphogenetic protein 2 and 4 (BMP-2 and -4) gene polymorphisms on bone density in postmenopausal Turkish women with osteoporosis. The frequency of single-nucleotide polymorphisms (SNPs) of BMP-2 and -4 genes was analyzed in 101 osteoporotic-postmenopausal women and 52 postmenopausal women with positive bone mineral density scores. We evaluated the ... more

DEGs; Function analysis; Osteoporosis; Protein-protein interaction network

This study used DNA microarray data to identify differentially expressed genes of osteoporosis and provide useful information for treatments of the disease. We downloaded gene expression data of Osteoporosis GSE35956 from the Gene Expression Omnibus database, which included five normal and five osteoporosis samples. We then identified the differentially expressed genes between normal and ... more

Bone mineral density; BsmI; Gene polymorphism; Meta-analysis; Vitamin D receptor

The vitamin D receptor BsmI gene polymorphism is reportedly associated with low bone mineral density (BMD) in postmenopausal women, but results from previous studies are conflicting. In the present study, we investigated the association between this polymorphism and the risk of low BMD through a meta-analysis of published studies. A literature search of the Pubmed, Embase, and ... more

B cell; Bone mineral density; Differentially expressed genes; Enrichment analysis; Functional analysis

We searched for key genes that could accurately predict bone mineral density. The gene expression profile GSE7429 was downloaded from the Gene Expression Omnibus database, which includes 20 samples, 10 with high and 10 with low bone mineral density. The differentially expressed genes (DEGs) were identified with packages in R language. Further, BLASTX was used to obtain COG function ... more

Genetic variants; GSTA1; GSTP1; Haplotypes

Glutathione S-transferases (GST) A1 and P1 are crucial enzymes involved in the biotransformation of drugs, carcinogens, and toxins, and their activity may influence drug response, susceptibility to diseases, and carcinogenesis. The genes encoding these enzymes, GSTA1 and GSTP1, have been examined in many studies because of their genetic variability, which may ... more

BMD; CYP17; CYP19; Estradiol; Osteoporosis; Polymorphism

Many clinical conditions, including osteoporosis, are associated with serum levels of sex steroids. Enzymes that regulate rate-limiting steps of steroidogenic pathways, such as CYP17 and CYP19, are also regarded as significant factors that may cause the development of these conditions. We investigated the association of two common polymorphisms, in the promoter region (T→C substitution) ... more
