Silica-based nanoparticles and methods of stimulating bone formation and suppressing bone resorption through modulation of nf-kb

Abstract

Osteoporosis, is an exceedingly common malady that leads to bone fracture and results from an imbalance in the rate of osteoblastic bone formation with respect to osteoclastic bone degradation. Nanotechnology has raised exciting possibilities for the development of novel therapeutic agents. Embodiments of the disclosure provide silica-based fluorescent nanoparticles endowed with natural bone targeting capabilities and expressing potent pro-osteoblastogenic and concomitant anti-osteoclastogenic activities in vitro and the capacity to increase bone mineral density in vivo. Embodiments of the disclosure can achieve their stimulatory effects on osteoblasts, and inhibitory effects on osteoclasts, in part by suppressing NF-KB signal transduction. Embodiments of the present disclosure provide for derivatives of silica-based nanoparticles that represent a novel class of dual anti-catabolic and pro-anabolic agents that may be applicable to the amelioration of numerous osteoporotic conditions.
