ABSTRACT Objectives: To investigate whether Forkhead family transcription factors are responsive to mechanical force and the resulting influence on the osteoclast differentiation mediated by human periodontal ligament cells (PDLCs). Materials and Methods: A high-throughput RNA sequencing assay was performed in compressive force–stimulated and control human PDLCs. Alteration of FOXM1, a member of the Forkhead family transcription factors, was further confirmed by Western blotting and quantitative reverse-transcription polymerase chain reaction. Expression of FOXM1 was inhibited by either small interfering RNA (siRNA) transfection or addition of its specific inhibitor Siomycin A. Then, cells were exposed to compressive force and co-cultured with the murine macrophage cell line Raw264.7, followed by tartrate-resistant acid phosphatase staining assay. Expression changes of receptor activator of nuclear factor κB ligand (RANKL) and osteoprotegetin (OPG) caused by FOXM1 suppression were measured. Alkaline phosphatase (ALP) staining, ALP activity assay, and crystal violet staining assay were performed after FOXM1 inhibition. Results: FOXM1 transcription decreased after mechanical stimulation in PDLCs. Inhibition of FOXM1 promoted force-induced osteoclast differentiation of RAW264.7 and upregulated the RANKL/OPG ratio in PDLCs. Interference of FOXM1 led to promoted osteogenic differentiation but decreased proliferation of PDLCs. Conclusions: FOXM1 is a novel mechano-responsive gene in human PDLCs. Suppressing FOXM1 expression could promote osteoclast differentiation as well as RANKL/OPG in human PDLCs. FOXM1 also plays a role in controlling PDLC differentiation and proliferation capacity.
