This study was designed to evaluate the potential therapeutic benefit of Hepatocyte Growth Factor (HGF)in Inflammatory Bowel Disease (IBD). Methods: Five adult F344 and 9 HLA-B27 rats aged 20-24 weeks were used in this study. Five HLA-B27 rats had a 14-day systemic (jugular vein) infusion initiated using subcutaneous osmotic pumps. Rats were divided into 3 groups: F344-no treatment(n=5), HLA-B27-no treatment (n=4),HLA-B27- HGF at 150 µg/kg/d (n=5). Following infusion, all animals were sacrificed, the GI tract harvested, and opened along its antimesenteric border. Total mucosal damage (% surface area) was measured using Image Analysis Software (Sigmascan 2.0). Microscopic analysis was performed and scored as follows: 0-no inflammation, 1-mild inflammation extending into submucosa, 2-moderate inflammation extending into muscularis propria, and 3- severe inflammation. Total RNA was extracted from colonic mucosal samples and assayed for Tumor Necrosis Factor-a (TNF), Interferon-? (INF), and Interleukin-2(IL-2) gene expression by RT/PCR. Glyceraldehyde-3-Phosphate Dehydrogenase (GAPD) was used as the internal standard. Statistical analysis was performed using Student’s t-test and expressed as mean ± SEM. Results: Conclusions: These data demonstrate that HGF significantly reduces gross (90% decrease) and histologic lesions (53% decrease) in a model of IBD. The beneficial effect of HGF is further supported by a significant decrease in gene expression of the inflammatory mediators, TNF(52% decrease) and INF(93% decrease). These results demonstrate a potential therapeutic role for HGF in IBD.
