Abstract

Osteoporosis is a major and growing healthcare concern as the population ages. The genes of both a Arg-Gly-Asp (RGD)-containing peptide and parathyroid hormone (PTH) were used to reduce bone loss induced by ovariectomy (OVX) in rats. Plasmids with either RGD or PTH gene were delivered into the quadriceps of OVX rats. The expression of the genes was detected by RT-PCR and radioimmunoassay. Analysis of bone mineral density, bone mechanical testing and bone mineral content indicated an improvement in bone properties in both RGD-transferred and PTH-transferred rats compared to OVX rats. Gene transfer of either RGD or PTH is therefore a possible approach to prevent bone loss in OVX rats thus providing a potential method to prevent osteoporosis in clinical situations.
