Figure 1From: Construction of an MUC-1 promoter driven, conditionally replicating adenovirus that expresses the sodium iodide symporter for gene therapy of breast cancerStructure of the Ad5AMUCH_RSV-NIS CRAd. The E1A gene is driven by the tumor-specific mucin-1 (MUC-1) promoter. The Rous sarcoma virus (RSV) promoter drives expression of the sodium iodide symporter (NIS) gene inserted at the E3 region.Back to article page
