(F) Flow cytometry analysis of cell death after treatment with Res-006 (65 μmol/L) only, Res-006 (65 μmol/L) and TEMPOL (Tem, 500 μmol/L), or Res-006 (65 μmol/L) and Mito-TEMPO (Mito, 300 μmol/L) treatments for 24 h. (G) HepG2 cells were treated with the indicated chemicals, and the total cellular extracts were prepared and subjected to Western blot analysis.
