Osteoporosis is a metabolic bone disorder characterized by low bone mineral density and decreased bone strength, leading to an increased risk of fractures with a consequent increase in morbidity and mortality. The current methods to estimate the fracture risk are very limited. microRNAs (miRNAs) have been considered as good biomarkers for many pathological processes, including osteoporosis. Some circulating miRNAs are associated with regulation of bone formation and differentiation of bone cells. The aim of this study, was to analyze the expression of miRNAs in serum of patients with osteoporosis (n = 20) and healthy controls (n = 20). Expression of 754 miRNAs was analyzed through quantitative real time RT-PCR arrays. Seven miRNAs showed significant differences between groups. The microRNAs miR-23b-3p, miR-140-3p and miR-885-5p were selected based on fold change and p-values (40.5, p = 0.038, 20.7, p = 0.045, and 2.2, p = 0.002; respectively) for validation in independent serum samples from patients with osteopenia (n = 28), osteoporosis (n = 26) and osteoporotic hip fracture (n = 21). After validation, we confirm differences across the groups for miR-23b-3p and miR-140-3p. Our data pointed miR-140-3p and miR-23b-3p as potential biomarkers candidates for osteoporosis in postmenopausal women.
