Abstract

Osteoporosis is a disease characterized by loss of bone mass and degeneration of the microstructure of bone. Resveratrol (3,5,4-tri-hydroxystilbene; RESV) may delay the onset of a variety of age-related diseases. In the present study, an ovariectomized female rat model was used to detect the changes in microRNAs (miRNAs/miRs) following RESV treatment. Subsequently, the target genes of miRNA were predicted using TargetScan software and determined using a dual-luciferase reporter assay. Finally, the role of miR-338-3p in the proliferation and differentiation of human osteoblast (HOB) cells was confirmed. The predominant finding of the present study was the identification of an intact mechanism of the effect of RESV in osteoporosis treatment. The results suggested that RESV suppresses miR-338-3p, followed by an increase in the expression of runt-related transcription factor 2 in HOB cells.
