| Outline of Final Research Achievements |
The crucial role of intestinal fibroblasts/myofibroblasts in inflammation, fibrosis, cancer microenvironment formation is well established. Available evidence suggests that part of fibroblasts/myofibroblasts function may reflect altered Ca2+ homeostasis. We focused TRPC6 function in growth factors-mediated signaling associated with tissue remodeling. Our data suggested that myofibroblast TRPC6 channel modulating stress fiber formation, cell-cell adhesion, extracellular matrix synthesis, and cytokine secretion. Growth factors-mediated signaling in intestinal myofibroblasts comprises several phosphorylation events, and forms an intricate network involving TRPC6-mediated signaling pathways. These results suggest that TRPC6-associated myofibroblastic differentiation could be an important process promoting intestinal remodeling, and thus a promising target for future anti-fibrotic and anti-tumorgenesis therapies in the gut.
