Abstract Background Pilon fractures are challenging to treat and carry a risk of delayed healing. MicroRNA (miRNA) is closely associated with various diseases due to its ability to regulate gene expression. Consequently, this study aimed to examine the connection between miR-1271-5p expression levels and pilon fracture healing processes, while also exploring the underlying mechanisms. The objective of this research was to provide valuable insights for the future clinical treatment of pilon fractures. Materials Venous blood samples were obtained for RNA extraction from patients with normal healing (n = 107) or delayed healing (n = 45) of pilon fractures. The expression levels of miR-1271-5p were measured using qRT-PCR. MiR-1271-5p and ZBTB7A biological functions in MC3T3-E1 cells were examined using the Cell Counting Kit-8 (CCK-8), flow cytometry, and qRT-PCR. Finally, an investigation into the underlying mechanisms was carried out using a dual luciferase reporter assay. Results This study found that, compared to those who healed normally, patients who experienced delayed healing of pilon fractures had significantly higher expression of miR-1271-5p. This suggests that miR-1271-5p may be an indicator for delayed healing in pilon fractures. Moreover, the upregulation of miR-1271-5p may result in a reduction of ZBTB7A expression, which is thought to mediate the effects of miR-1271-5p on MC3T3-E1 cell activities. Conclusions MiR-1271-5p was involved in the healing processes of pilon fractures via targeting ZBTB7A. MiR-1271-5p was a possible target for the therapy of pilon fractures. |
