Outline of Final Research Achievements |
This study was designed to investigate the mechanism of pancreatic fibrogenesis via Wnt signaling in pancreatic myofibroblasts (activated stellate cells). Microarray assay showed that IL-1 stimulation induced the mRNA level of wnt2, 5a, and RUNX. On the other hands, TGF-β stimulation induced the mRNA level of Wnt 4, 9,11. Wnt 4 and 5a expression were significantly increased in the mild fibrotic area in the cerulean-induced chronic pancreatitis model mice. These findings suggest that Wnt signaling may be involved in pancreatic fibrogenesis in response to various inflammatory and fibrotic mediators.
