| Research Abstract |
In inflammatory condition, oxidative stress increases where Reactive Oxygen species (ROS) damages cell function. On the other hand, ROS production is strictly regulated in the normal metabolism of cells and plays important roles in cell signaling. TRP channels react to a variety of environmental stress. Especially, TRPC subfamilies react to oxidative stress. ROS keeps TRPC channels open and Ca influx occurs which results in the increased Ca concentration in cytoplasm. Ca is known to be an important second messenger of cell signaling and the increase of Ca in cytoplasm causes several reaction. In this study, TRPC3 and 5 overexpressing fibroblasts were generated and and the function of these channeles in oxidative stress were analyzed. Fibroblast Populated Collagen Lattice with TRPC3 showed increased contractile activity in oxidative stressed condition.
