Figure 6

(A, B) HepG2 and MHCC97-H cells were treated as detailed in the legend to Figure4. Annexin V assays revealed that the cell viability of HepG2 and MHCC97-H cells transfected with pcDNA3.1-Tg737 and further incubated with fresh DMEM (1% FBS) for 12 h under hypoxia were not significantly different from cells without plasmid transfection. The data from HepG2 and MHCC97-H cells transfected with pcDNA3.1 (−) or incubated with LipofectamineTM 2000 excluded any liposome/pEGFP-C1-related effects on cell viability.I: cells without plasmid transfection; II: cells transfected with pcDNA3.1 (−); III: cells incubated with LipofectamineTM 2000; IV: cells transfected with pcDNA3.1-Tg737.
