Keloids are fibroproliferative dermal lesions characterized by the proliferation of fibroblasts and the formation of excess scar tissue, for which no effective treatment exists. We transfected a replication-incompetent adenovirus vector expressing green fluorescent protein and interleukin-24 gene (Ad-GFP/IL-24) into keloid fibroblasts (KF) and normal dermal fibroblasts (NDF) in vitro to investigate the suppression effects by observation on cell lines growth, apoptosis, mitosis cycle, etc. The expression of GFP and IL-24 mRNA confirmed that Ad-GFP/IL-24 was transfected into KF and NDF successfully. The expression level of secreting IL-24 protein detected by enzyme-linked immunosorbent assay in Ad-GFP/IL-24-treated KF and PBS-treated NDF was higher than controls; treatment with Ad-GFP/IL-24 in KF induced growth suppression (71.83% +/- 6.67%, P < 0.05 to 9.79% +/- 3.34%, P < 0.01), apoptosis (24.2% +/- 3.08% to 66.51% +/- 5.29%, P < 0.01) and increased the percentage of the G2/M phase (42.26% +/- 6.44%, P < 0.01) in KF but not in NDF. The data showed that the exogenous IL-24 gene could selectively inhibit human KF proliferation and induce significant apoptosis.
