Implication

Experimental study reveals direct interleukin-6 suppression of osteoclast differentiation in progenitor cells, indicating a dual regulatory role in bone homeostasis.

Key Points

To determine whether interleukin-6 directly influences osteoclast progenitor differentiation and to characterize the downstream molecular signaling pathways involved.
Treated osteoclast progenitor cells directly with interleukin-6 during receptor activator of NF-κB ligand (RANKL)-stimulated osteoclastogenesis.
Assessed changes in RANK signaling pathways, focusing on IκB degradation and JNK phosphorylation.
Conducted microarray analysis to profile transcriptional alterations in osteoclast progenitors following costimulation with interleukin-6 and RANKL.
Interleukin-6 directly suppressed osteoclast progenitor differentiation by selectively inhibiting RANK-mediated IκB degradation and JNK activation.
Costimulation with interleukin-6 and RANKL upregulated expression of MAPK phosphatase genes MKP1 and MKP7 and downregulated ubiquitin-pathway genes Senp2 and Cul4A.
