Article Title: Targeting MDK alleviates bone loss via dual regulation of osteogenic differentiation and inflammatory cytokine expression

doi: 10.1016/j.gendis.2025.101931

Figure Lengend Snippet: Schematic representation of MDK alleviating bone loss. MDK is significantly elevated in the serum of postmenopausal osteoporotic women and ovariectomized mice. Due to estrogen deficiency, iMDK alleviates bone loss by promoting bone formation and inhibiting inflammatory factors. Recombinant MDK protein inhibits osteogenic differentiation through the PI3K/AKT signaling pathway and up-regulates inflammatory factors IL-6, TNF-α, and IL-1β via the NF-κB signaling pathway.
