HGF and c-Met protein expression in gastric mucosa by ELISA.

On day 21, the expression of HGF protein in gastric ulcer was significantly higher in the TPH-treated group than in the TP-treated and model control groups. However, the protein expression of c-Met after 21 days of TPH treatment was not significantly different from the TP-treated and model control groups.

HGF = hepatocyte growth factor, ELISA = enzyme-linked immunosorbent assay, TPH = attenuated Salmonella typhimurium strain carrying a eukaryotic expression vector encodes the human HGF gene, TP = attenuated Salmonella typhimurium strain with a eukaryotic expression vector.

^*P < 0.01, TPH group vs. TP and control groups.
