Background.
Gukang capsule (GKC) is a traditional Chinese medicine formulation which has been used extensively in the clinical treatment of bone fractures.
However, the mechanisms underlying its effects on fracture healing remain unclear.
Methods.
In this study we used a rabbit radius fracture model, and we measured the serum content of bone alkaline phosphatase (ALP), calcium, and phosphorus and examined pathology of the fracture site as indicators of the fracture healing effects of GKC.
SaOS-2 human osteosarcoma cells were used to measure (i) ALP activity, (ii) ornithine transcarbamylase (OTC), calcium, and mineralization levels, (iii) the expression of osteogenic-related genes, that is, runt-related transcription factor 2 (RUNX2), bone morphogenetic protein 2 (BMP2), collagen I (COL-I), osteopontin (OPN), OTC, and osterix (Osx), and (iv) the expression of key proteins in the Wnt/β-catenin and BMP/SMAD signaling pathways to study the mechanisms by which GKC promotes fracture healing.
Results.
We found that GKC effectively promotes radius fracture healing in rabbits and enhances ALP activity, increases OTC and calcium levels, and stimulates the formation of mineralized nodules in SaOS-2 cells.
Moreover, COL-I, OTC, Osx, BMP2, and OPN expression levels were higher in SaOS-2 cells treated with GKC than control cells.
GKC upregulates glycogen synthase kinase 3β (GSK3β) phosphorylation and Smad1/5 and β-catenin protein levels, thereby activating Wnt/β-catenin and BMP/Smad signaling pathways.
Inhibitors of the Wnt/β-catenin and BMP/Smad signaling pathways (DKK1 and Noggin, respectively) suppress the osteogenic effects of GKC.
Conclusions.
GKC promotes fracture healing by activating the Wnt/β-catenin and BMP/Smad signaling pathways and increasing osteoprotegerin (OPG) secretion by osteoblasts (OBs), which prevents receptor activator of nuclear factor kappa B ligand (RANKL) binding to RANK.
