ABSTRACT

Objective:

To investigate the expression of miR-92a-3p in senile osteoporosis (OP) and its diagnostic value in hip fragility fractures.

Methods:

With the help of the National Center for Biotechnology Information (NCBI) website, the data sets related to OP and miRNA were retrieved and analyzed and screened to obtain the target miRNA. Serum samples were collectedfrom 53 OP patients and 24 healthy people, and the OP patients were divided into hip fragility fracture group (OP_F; n=30) and no hip fragility fracture group (OP_WF; n=23). The subjects' bone mineral density and serum bone metabolism markers were measured calcium, phosphorus, parathyroid hormone, 25-hydroxyvitamin D, bone alkaline phosphatase, serum C-terminal peptide. The expression levels of target miRNAs in serum samples were detected by qRT-PCR. Chi-square test, t test, Spearman rank correlation and receiver operating characteristic curve (ROC curve) were used to analyze the potential relationship between the expression level of miR-92a-3p and the clinical characteristics of patients.

Results:

According to the analysis of NCBI website, the expression of miR-92a-3p in OP patients was higher ( t=3.41, P=0.007) than that in healthy people, and the expression level of miR-1304-5p was lower ( t=5.13, P<0.001). qRT-PCR experiments confirmed the above results, and further found that the expression of miR-92a-3p in the OP_F group was significantly higher than that in the OP_WF group (t=3.01, P=0.004), but there was no significant difference in miR-1304-5p between the two groups (t=0.71, P=0.480). Compared with the healthy control group, the BMI ( t=2.71, P=0.008), bone mineral density score ( t=29.02, P<0.001), calcium ( t=61.20, P<0.001), phosphorus ( t=2.54, P=0.013), 25-hydroxyvitamin D (t=3.01, P=0.004) ,bone alkaline phosphatase ( t=12.56, P<0.001), and serum C-terminal peptide ( t=7.52, P<0.001) levels were statistically different between the OP patient group and the healthy control group. Compared with the OP_WF group, the bone mineral density score ( t=2.08, P=0.042), calcium ( t=15.75, P<0.001), bone alkaline phosphatase ( t=2.02, P=0.049) and serum C-terminal peptide ( t=3.39, P=0.001) levels were statistically different between the OP_F group and the OP_WF group. Bone mineral density score and bone alkaline phosphatase concentration were related to the expression of miR-92a-3p and were negatively and positively correlated ( r=0.416, P=0.022), respectively ( r=-0.403, P=0.027). The area under the ROC curve was 0.723, and the level of miR-92a-3p had potential significance in the diagnosis of hip fragility fractures ( P=0.006) .

Conclusion:

miR-92a-3p is highly expressed in OP and has biological significance for the diagnosis of hip fragility fractures.
