Figure 2From: Targeted gene therapy of nasopharyngeal cancer in vitro and in vivo by enhanced thymidine kinase expression driven by human TERT promoter and CMV enhancerAmplification curves of fluorescence quantitative PCR. Shown are the amplification curves of β-actin (a) and TK gene (b) from NPC 5-8F cells transfected with pGL3-basic-hTERTp-TK-EGFP-CMV plasmid (1), from MCF-7 transfected with pGL3-basic-hTERTp-TK-EGFP-CMV plasmid (2), from NPC 5-8F cells transfected with pGL3-basic-hTERTp-TK-EGFP plasmid (3), from NPC 5-8F cells transfected with pGL3-basic-TK-EGFP plasmid (4), and from ECV cells transfected with pGL3-basic-hTERTp-TK-EGFP-CMV plasmid (5).Back to article page
