We previously showed that the promoter region of the human epidermal growth factor receptor (hEGFR) gene elicits high transduction efficiency, with transgene expression restricted to canine breast tumor cells. However, it was unclear whether this promoter induces tumor cell-specific transgene expression in canine urothelial carcinoma cells. Furthermore, compared with studies in human cancer cells, the utility of the telomerase reverse transcriptase (TERT) gene promoter for therapeutic transgene expression in canine cancer cells has not been evaluated thus far. Here, we compared the activity of these promoters in canine mammary tumor and urothelial carcinoma cells. Our results showed that compared with the TERT promoter, the hEGFR promoter was more useful as a tumor-specific promoter to induce efficient transgene expression in canine tumor cells.
