Proteomic analysis of scNT-N and scNT-MUC by 2-DE and Western blot. A) Representative up- and down-regulated proteins from scNT-N and scNT-MUC are shown. B and C) Western blot analysis of ROS- and apoptosis-related proteins in scNT-N and scNT-MUC. The amount of total protein loaded per lane was 15-30 μg; β-actin was analyzed as a loading control. D) Fold changes of differentially expressed proteins in scNT-N and scNT-MUC by 2-DE gel or Western blotting.
