| Outline of Final Research Achievements |
Keloids are fibro-proliferative diseases characterized by the accumulation of an extracellular matrix such as collagen. The aberrant proliferation and production of extracellular matrix have been related to the expression pattern of different cytokines, including TGF-β and IL-6 in keloid fibroblasts. The therapies which target to these cytokines and related molecules have possibility to ameliorate keloid. In this study, we evaluated the effects of HDAC inhibitor and MEK inhibitor, as the candidate chemicals for targeting the pathway, against keloid fibroblasts. HDAC inhibitor suppressed proliferation and production of collagen in keloid fibroblasts, and MEK inhibitor weakly suppresses those. Moreover, we investigated the effect of the combination of HDAC inhibitor and MEK inhibitor. As the results, the combination did not show the significant combined effect to suppress keloid fibroblasts.
