Outline of Final Research Achievements |
Systemic sclerosis (SSc) is connective tissue disorder characterized by severe fibrosis of the skin and various internal organs. Tight skin (TSK/+) mouse is a putative murine model of SSc characterized by excessive collagen deposition in skin. Vorinostat, a kind of histone deacetylase inhibitor, was injected subcutaneously into the back of the TSK/+ and wild type mice. As a result, vorinostat could not decrease the development of TSK mouse skin fibrosis. We examined the suitable concentration of the vorinostat in vitro by using human skin fibroblasts of SSc or normal human skin. However, mRNA expressions of type I collagen or fibrogenic cytokines were not markedly attenuated by vorinostat administration. These results suggest that vorinostat have little specificity on the SSc skin fibrosis. Also, these result may reflect the fact that vorinostat may have little effect on the HDAC inhibiton relative to other HDAC inhibitors.
