ABSTRACT
BACKGROUND:
Osteoporosis is one of the most commonly diagnosed age-related bone diseases worldwide, and it is also one of the leading causes of fracture. MicroRNAs (miRNAs) are critical molecular regulators that are involved in the bone re-modelling processes, and the circulating miRNAs were stable in the peripheral blood. Thus, to detect the level of miRNAs in plasma of osteoporotic patients may be an efficient, repeatable, and inexpensive method for the early diagnosis and evaluation of the therapeutic efficacy of osteoporosis. The aim of the present study was to investigate the potential diagnostic value of miR-100 in plasma of patients with osteoporosis.METHODS:
A total of 120 osteoporotic patients were recruited and 120 healthy individuals were also included as the control group. The plasma of the participants was collected and the RNAs were extracted. The expressions of miR-100 in different clinical samples were examined using the RT-qPCR method. Furthermore, receiver operating characteristics curve (ROC) was drawn to determine the diagnostic value of miR-100 for osteoporosis. Next, the correlation between the plasma levels of miR-100 and T-scores of the patients were evaluated and, finally, the correlation between the plasma level of miR-100 and the expression levels of 25OH-D2 and 25OH-D3 were analyzed.RESULTS:
miR-100 was significantly increased in plasma of patients with osteoporosis in comparison with healthy individuals; moreover, results of ROC analysis indicated that plasma level of miR-100 is a sensitive biomarker that could distinguish osteoporosis patients from healthy controls (AUC, 0.8916, 95% confidence interval (CI), 0.8468 to 0.9364). Furthermore, miR-100 was found to be negatively correlated with both vBMD (r = -0.3117, p = 0.0005) and Lumbar Spine L2-L4 T-score in patients with osteoporosis (r = -0.2929, p = 0.012). Finally, the plasma level of miR-100 was negatively correlated with the levels of 25OH-D2 (r = -0.3002, p = 0.0008) and 25OH-D3 (r = -0.3105, p = 0.0006) of the osteoporotic patients.CONCLUSIONS:
miR-100 was abnormally increased in the plasma of osteoporotic patients, suggesting that circulating miR-100 could serve as potential biomarker for the diagnosis and treatment osteoporosis.
