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.

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.
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. Microarray analyses of monocytes were performed using Affymetrix HG-133A arrays in 80 Caucasian females, including 40 high (20 pre- and 20 postmanopausal) and 40 low hip BMD (20 pre- and 20 postmanopausal) subjects

Project description:B cells produce important cytokines regulate bone metabolism. We comparison gene expression patterns of circulating B cells in blood from 20 postmenopausal females with low or high bone mineral density (BMD): 10 low BMD vs. 10 high BMD. In total 29 differentially expressed genes were identified including some novel genes to be relevant to bone metabolism. These results provide insight into the role of B cells in pathologic osteoporosis. Keywords: disease state analysis
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..
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. Keywords: disease state analysis
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.
