Figure 3From: Mitochondrial targeted catalase suppresses invasive breast cancer in mice Tumor cells expressing mCAT are resistant to oxidative stress. A. Primary PyMT tumor cells expressing mCAT have lower levels of ROS compared to tumors cells from wild type littermates. p ≤ 0.05. B. PyMT mammary tumors expressing mCAT are resistant to H2O2 compared to PyMT mammary tumors negative for mCAT, *p < 0.05, **p < 0.001.Back to article page
