SOD2 and colorectal cancer: Here, we identify that Oligo-Fucoidan combined with cisplatin treatment induces ROS signaling in colorectal cancer cells which can be suppressed by antioxidants (NAC, MitoQ and DPI) (Supplementary Figure S7B), demonstrating that Oligo-Fucoidan and cisplatin together induce the oxidative signaling axis of YY1/EGFR/MnSOD (Supplementary Figure S7).
