Abstract

Wear particles serve a central role in periprosthetic osteolysis, which leads to the aseptic loosening of prostheses. In the present study a lentiviral vector was constructed to silence macrophage colony stimulating factor (M‑CSF) and receptor activator of nuclear factor κ‑B ligand (RANKL) genes, which synergistically inhibit osteoclast formation and differentiation. To confirm the role of the calcineurin/nuclear factor of activated T cells (NFAT) pathway in osteolysis, we transduced murine macrophage/monocyte RAW264.7 cells with M‑CSF‑short hairpin (sh)RNA‑RANKL‑shRNA. Tumor necrosis factor‑α (TNF‑α) protein levels were evaluated using enzyme‑linked immunosorbent assay. Transduced RAW264.7 cells were cultured in Transwell chambers in the presence of 0.1 mg/ml titanium particles to investigate the capacity of TNF‑α inhibition to reduce wear debris‑induced inflammation. RANKL, M‑CSF, TNF‑α, interleukin (IL)‑1β, IL‑6 and NFATc1 mRNA levels were also assessed by reverse transcription‑quantitative polymerase chain reaction. Osteoclastogenesis was measured by tartrate‑resistant acid phosphatase (TRAP) mRNA quantification. Lentiviral‑mediated double gene inhibition is known to be able to completely inhibit inflammatory osteolysis, simultaneously decreasing the number of NFATc1‑ and TRAP‑positive cells. The present study confirmed that the combined silencing of M‑CSF and RANKL genes can inhibit the osteolysis induced by the wear particles around the prosthesis. The calcineurin/NFAT pathway serves a role in the prevention of prosthesis loosening.
