Abstract

OBJECTIVE:

To investigate the effects and related mechanisms of miR-204 on fracture healing.

MATERIALS AND METHODS:

Mouse osteoblastic cell line MC3T3-E1 was used in our experiment. Three groups were established to investigate the potential function between miR-204 and osteoblastic cells: miR-NC group (negative control), miR-204 mimics group (MC3T3-E1 cells transfected with miR-204 mimics) and miR-204 mimics + inhibitor group (MC3T3-E1 cells transfected with miR-204 mimics and inhibitor). After incubation, cell viability, activity of caspase-3, and migration ability of MC3T3-E1 cells, were measured. Further, the expression levels of Runt-related transcription factor 2 (RUNX2) and Osterix (OSX) were detected and analyzed.

RESULTS:

Compared with miR-NC group, the cell viability and migration ability of MC3T3-E1 cells were enhanced while the activity of caspase-3 was respectively mitigated. Besides, the expression level of RUNX2 and OSX was increased by treatment of miR-204 mimics. However, these variations of the indicators were reversed by the intervention using miR-204 inhibitor.

CONCLUSIONS:

We revealed the promotion effect of miR-204 on fracture healing, indicating that miR-204 could be a potential therapeutic target for the treatment of a fracture.
