We focused on Smad4, because it is essential for the activation of Smad-dependent target genes. We aimed to explore the possibility of inhibiting scar formation after wounding by blocking TGF-β signalling by means of a gene therapy approach using adenovirus-mediated expression of mutant Smad4. The coding sequence of the dominant-negative mutant Smad4ΔM4, which has a deletion in the linker region of Δ275-322, was introduced by homologous recombination into an adenovirus vector to generate the recombinant vector Ad-ΔM4, which encoded Smad4ΔM4. Mouse fibroblast NIH 3T3 cells were transfected with Ad-ΔM4 and cell proliferation, collagen protein production, and the expression of collagen type I and type III mRNA were evaluated in vitro using a cell proliferation test, western blot analysis, and RT-PCR, respectively. Cell proliferation and the expression of collagen type I and type III mRNA and protein were all inhibited by the transfection of Ad-ΔM4. In vivo, Ad-ΔM4 was applied externally to wounds on rats, and histological examination and quantification of the scars were performed to evaluate the curative effect. The transfection of Ad-ΔM4 successfully inhibited scar formation in rat wounds. In conclusion, Ad-ΔM4 can block the TGF-β signalling of mouse wound cells effectively. In addition, gene therapy with Ad-ΔM4 can effectively inhibit wound scarring in rats and may potentially be applied to clinical treatment of scars."xsd:string |
