Abstract
Objective

This study aimed to investigate the effect of Runx2 silencing on autophagy and RANKL expression in mouse osteoblasts, and provide an experimental basis to assess obstacles in dental eruption.

Methods

In accordance with previously reported methods, LVpFU-GW-016PSC60109-1 virus was used to transfect mouse osteoblasts (MOI = 40). Target gene expression was assessed via cytometer, and the effect of silencing Runx2 was assessed via a two-step quantitative real-time polymerase chain reaction (qRT-PCR)-based method. Western blotting was performed to assess LC3, Beclin-1 and RANKL expression.

Results

As confirmed via qRT-PCR analysis, Runx2 was efficiently silenced in the experimental group (>90% efficiency). Western blotting revealed that LC3 and RANKL proteins were significantly down -regulated in the experimental group (group KD), their expression levels being particularly lower than those in the control group (group NC). However, Beclin-1 protein expression was not significantly different from that of the control.

Conclusion

Upon Runx2 silencing, autophagy-related proteins and RANKL were repressed in osteoblasts, thereby potentially causing the tooth eruption disorder.
