Abstract (original English)

Biodegradable magnesium (Mg) materials are considered ideal as osteosynthesis implants. However, clinical application has proven complex. This is primarily associated with the issue of reducing the extent of implant degradation to a range acceptable for the human body, while simultaneously enhancing osteogenesis or osteoinduction. In the present study, a combination of Mg ions and low‑intensity pulsed ultrasound (LIPUS) treatment was applied in hFOB 1.19 human osteoblast cells as a potential strategy to resolve this issue. A total of 7,314 differentially expressed genes (DEGs) and 826 shared DEGs in hFOB1.19 osteoblast cells were identified by microarray analysis following treatment with Mg and/or LIPUS. Gene Ontology analysis demonstrated that among cells treated with a combination of Mg and LIPUS, DEGs were significantly enriched in various functional annotations, including 'wound healing', 'transforming growth factor beta receptor signaling pathway', 'transcription, DNA‑templated', 'receptor complex', 'nucleus', 'SMAD protein complex', 'DNA binding', 'metal ion binding' and 'GTPase activator activity'. Notably, the transforming growth factor (TGF)‑β, mitogen‑activated protein kinase (MAPK) and tumor necrosis factor (TNF) signaling pathways were preferentially overrepresented in the Mg and LIPUS combination group, which was subsequently confirmed by reverse transcription‑quan
