Figure Lengend Snippet: MnSOD contributes to decreased mitochondrial superoxide and apoptotic cells in HepG2.215 cells. A: After 6 d, the interference effect of MnSOD siRNA (siMnSOD) was analyzed by Western blot analysis. MnSOD siRNA (siMnSOD) or non-specific siRNA (siCTRL) was transfected into HepG2.215 cells for 12 h before serum depletion; B: After 6 d, cells were harvested for quantification of mitochondrial superoxide anion formation by flow cytometry. In parallel, (C) cell viability and (D) apoptotic cells were separately determined by MTT assay and flow cytometry. aP < 0.05 and bP < 0.01 vs siCTRL group.
Article Snippet: RNA interference The siRNAs for silencing AMPK, MnSOD and HBx genes as well as scrambled siRNA were purchased from Ribobio (Guangzhou, China).
