Objective: The purpose of the present study was to quantify serological biomarkers, namely adiponectin, leptin, E-selectin, ICAM-1 (intercelluar cell adhesion molecule-1), IGF-1 (insulin-like growth factor 1), MCSF (macrophage colony-stimulationg factor), IL-6, IL-10 and IL-17), in fertile and postmenopausal women. The relationship of these parameters to obesity and bone status has been analysed. Methods: 96 fertile and 107 postmenopausal women were enrolled in this study. The detection of multiple biomarkers, cytokines, growth factors, adhesion molecules and others, was performed by protein microarray. Results: Adipopnectin was up-regulated in postmenopausal control and ICAM-1 in postmenopausal obese women when compared to fertile obese women (p<0.05). Significant negative correlation was between IL-6 and age (r=-0.177, p<0.05). The soluble form of ICAM-1 was higher in women with osteopenia, but not with osteoporosis, in comparison to the control group. IL-6 was decreased in women affected by osteoporosis. Conclusion: In context to obesity, bone status and ageing, we have found alterations in adiponectin, ICAM-1, and IL-6 parameters in postmenopausal women. We identified several statistically significant correlations between soluble biomarkers and cell populations (e.g. between IGF-1 and B-lymphocytes; IL-6 and dendritic cells; IL-10 and naive T cells, etc.).
