The 70 fragility fracture patients and 45 healthy controls were enrolled in this study. Quantitative real-time PCR (qRT-PCR) was used for the measurement of the expression levels of miR-193a-3p and PTEN. MTT assay and flow cytometry were used to detect cell viability and apoptosis in the mouse osteoblastic cell line MC3T3-E1. Luciferase reporter assay was performed to confirm the correlation of miR-193a-3p with PTEN. The serum expression level of miR-193a-3p showed no significant change in fracture patients 7 days after fixation treatment, but over time, there was a significant decrease in the expression at 14 days and 21 days after treatment (P < 0.01). Overexpression of miR-193a-3p significantly enhanced cell viability and inhibited cell apoptosis in MC3T3-E1 cells (P < 0.001). Serum P TEN level in fracture patients was increased gradually during the fracture healing process (P < 0.01). PTEN was demonstrated to be a target gene of miR-9-5p and reversed the effect of miR-193a-3p on cell viability and apoptosis (P < 0.001). miR-193a-3p promoted fracture healing via regulating PTEN and may serve as a novel potential target for enhancing bone repair of fragility fracture.
