Cellular signatures in human blood track bone mineral density in postmenopausal women

Project description:Osteoclasts are sole bone-resorbing cells and are formed by the fusion of osteoclast precursor cells (OCPs) derived from myeloid lineage cells. Animal studies reveal that circulating osteoclast precursor cells (cOCPs) in blood travel to bone and fuse with bone-resident osteoclasts. However, the characteristics of human cOCPs and their association with bone diseases remain elusive. We have identified and characterized human cOCPs and found a positive association between cOCPs and osteoporosis. Sorted cOCPs have a higher osteoclastogenic potential than other myeloid cells and effectively differentiate into osteoclasts. cOCPs exhibit distinct morphology and transcriptomic signatures. The frequency of cOCPs in the blood varies among treatment-naïve postmenopausal women and has an inverse correlation with lumbar spine bone density and a positive correlation with serum CTX, a bone resorption marker. The increased cOCPs in treatment-naïve osteoporosis patients were significantly diminished by denosumab, a widely used antiresorptive therapy. Our study reveals the distinctive identity of human cOCPs and the potential link between the dynamic regulation of cOCPs and osteoporosis and its treatment. Taken together, our study enhances our understanding of human cOCPs and highlights a potential opportunity to measure cOCPs through a simple blood test, which could potentially identify high-risk individuals.

Gene expression study of blood monocytes in pre- and postmenopausal females with low or high bone mineral density (HuEx-1_0-st-v2)

LC-MSMS of postmenopausal with low BMD

Project description:Postmenopausal osteoporosis (PMOP) is a major global public health concern and older women are more susceptible to experiencing fragility fractures. Our study investigated the associations between circulating proteins with bone mineral density (BMD) in postmenopausal women with or without low BMD (osteoporosis and osteopenia) to explore the pathogenesis of PMOP and discover novel biomarkers for this disease..

Gene expression study of blood monocytes in pre- and postmenopausal females with low or high bone mineral density (HuEx-1_0-st-v2)

Project description:Comparison of circulating monocytes from pre- and postmenopausal females with low or high bone mineral density (BMD). Circulating monocytes are progenitors of osteoclasts, and produce factors important to bone metabolism. Results provide insight into the role of monocytes in osteoporosis. We identify osteoporosis genes by microarray analyses of monocytes in high vs. low hip BMD (bone mineral density) subjects. Microarray analyses of monocytes were performed using Affymetrix 1.0 ST arrays in 73 Caucasian females (age: 47-56) with extremely high (mean ZBMD =1.38, n=42, 16 pre- and 26 postmenopausal subjects) or low hip BMD (mean ZBMD=-1.05, n=31, 15 pre- and 16 postmenopausal subjects). Differential gene expression analysis in high vs. low BMD subjects was conducted in the total cohort as well as pre- and post-menopausal subjects.

Transcription profiling of human B-lymphocytes from postmenopausal female smokers with high or low bone mineral density

Project description:B cells produce important cytokines regulate bone metabolism. We comparison gene expression patterns of circulating B cells in blood from 20 postmenopausal female smokers with low or high bone mineral density (BMD): 10 low BMD vs. 10 high BMD. In total 17 differentially expressed genes were identified with smoking-related osteoporosis. Experiment Overall Design: B cells were isolated from 70 ml of whole blood from each of 20 postmenopausal female smokers, 10 with high BMD and 10 with low BMD, using B cell positive isolation method (Dynabeads CD19,Pan B) from Invitrogen Life Technologies Dynal Biotech Inc,CA. Total RNA was extracted from B cells using Qiagen RNeasy Mini Kit.A total of 4ug totalRNA was used to produced targets for each subject according to standard Affymetrix procedures. Hybridization was made for each subject. Robust Multiarray Algorithm was used to normalize the expression data and smoking-related genes were analyzed using two-way ANOVA under mutiple-testing adjustment combined with our previous GEO data (GSE7429).

Transcription profiling of bone biopsies from postmenopausal females identifies 8 genes highly associated with bone mineral density

Project description:Postmenopausal females (50 85 years) representing a wide range of Bone mineral densities (BMDs) were consecutively registered, excluding persons who had diseases and medications known to affect bone remodeling. Low energy fracture(s) occurred in 32 (38 %). Trans-iliacal bone biopsies (84) were submitted to Affymetrix microarray expression analysis to study the relationship between BMD or osteoporosis and gene expression.

Expression data from breast samples of postmenopausal women

Project description:The objective of the study was to comprehensively compare the genomic profiles in the breast of parous and nulliparous postmenopausal women to identify genes that permanently change their expression following pregnancy. The study was designed as a two-phase approach. In the discovery phase, we compared breast genomic profiles of 37 parous with 18 nulliparous postmenopausal women. In the validation phase, confirmation of the genomic patterns observed in the discovery phase was sought in an independent set of 30 parous and 22 nulliparous postmenopausal women.

Gene expression study of blood monocytes in pre- and postmenopausal females with low or high bone mineral density (HG-U133A)

Project description:Comparison of circulating monocytes from pre- and postmanopausal females with low or high bone mineral density (BMD). Circulating monocytes are progenitors of osteoclasts, and produce factors important to bone metabolism. Results provide insight into the role of monocytes in osteoporosis. We identify osteoporosis genes by microarray analyses of monocytes in high vs. low hip BMD (bone mineral density) subjects.
