Our previous study found that honokiol (HNK), a small-molecule polyphenol, can inhibit neointimal hyperplasia after balloon injury, but its specific mechanism is still unclear. Moreover, poor water solubility as well as low bioavailability of honokiol has limited its practical use.Methods: We used mesoporous silica nanoparticles (MSNPs) as a standard substance to encapsulate HNK and then assemble into honokiol-mesoporous silica nanoparticles, and we investigated the effect of these nanoparticles on the process of restenosis after common carotid artery injury in rats.Results: We report a promising delivery system that loads HNK into MSNPs and finally assembles it into a nanocomposite particle. These HNK-MSNPs not merely inhibited proliferation and migration of VSMCs by reducing phosphorylation of Smad3, but also showed a higher suppression of intimal thickening than the free-honokiol-treated group in a rat model of balloon injury.Conclusion: To sum up, this drug delivery system supplies a potent nano-platform for improving the biological effects of HNK and provides a promising strategy for preventing vascular restenosis.Keywords: mesoporous silica nanoparticles, honokiol, vascular smooth muscle cells, TGF-β pathway, balloon injury, intimal thickening, restenosisWei XFang ZSheng JWang YLu PDove Medical Pressarticlemesoporous silica nanoparticleshonokiolvascular smooth muscle cellstgf-β pathwayballoon injuryintimal thickeningrestenosisMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 5239-5252 (2020) |
