Transcriptome Analysis of Hydrogen Inhibits Osteoclastogenesis of Mouse Bone Marrow Mononuclear Cells
Overview

Hydrogen (H) is a major biodegradation product of implanted magnesium (Mg) alloys that are commonly used in the healing of bone fractures. Our earlier study showed that H can inhibit mouse bone marrow mononuclear cell (BMMC) osteoclastogenesis during the differentiation of these cells into osteoclasts, thereby facilitating fracture healing. However, the way by which H inhibits osteoclastogenesis remains to be elucidated. The present study used RNA-sequencing to study the transcriptome of H-exposed BMMCs in an osteoclast-induced environment and identified the target genes and signaling pathways through which H exerts its biological effects. Several upregulated genes were identified: , , , , , , , , and . Several downregulated genes were also revealed: , , , , , , , , and 5. These differentially expressed genes were mainly involved in osteoclast differentiation cascades, as well as PI3K-AKT, Forkhead box O (FoxO), MAPK, peroxisome proliferator-activated receptor (PPAR), TNF, TGF-β, JAK-STAT, RAS, VEGF, hypoxia-inducible factor (HIF-1) and AMPK signaling pathways. In summary, the present study revealed the key genes and signaling pathways involved in the H-mediated inhibition of osteoclastogenesis, thereby providing a theoretical basis for the significance of H and an experimental basis for the application of Mg alloys in the treatment of osteoporosis.
