Staining for met-ENK in pancreata at week 10 revealed significantly increased densities in HSV-ENK-treated animals (Fig 4D, 954.6 ± 77.6 arbitrary units) compared to vehicle or HSV-β-gal-treated animals with pancreatitis (Fig 4B and 4C, 452.2 ± 9.6 and 504.5 ± 18.2 arbitrary units, respectively), or the naïve animals (Fig 4A) (402.1 ± 10.7 arbitrary units). The gene discussed is MET; the disease is pancreatitis.
