Reactive Oxygen Species (continued)
We've now gotten to measure ROS in three cancer lines and a fibroblast control. Our hypothesis was that cancers overproduced ROS, but kept them within survivable bounds by also overexpressing UCP2.
So far we've been right! A colon cancer line (SW 480) and an aggressive breast cancer line (MDA MB 231) both expressed 3-4 times as much ROS as did our fibroblast control cells.
Our other breast cancer cell line, MCF7, is much less aggressive and expresses barely more UCP2 than fibroblasts. (See our graph of Other Experimental Data in our original project description). Therefore MCF7 would be predicted to have ROS levels not very different from fibroblasts, which is what we found.
