Figure 2.hTERT is expressed in different species. hTERT expression levels in pLOC-hTERT infected human BJ, human lung fibroblasts, non-human primate lung fibroblasts, porcine lung fibroblasts, canine lung fibroblasts, rabbit lung fibroblasts, rat lung fibroblasts, and in Tert−/− mouse embryonic fibroblasts. pLOC-empty infected cells were used as negative controls and hTERT expression was undetected in all cell lines. Transcriptional hTERT was analyzed 10 days post-infection, and samples were analyzed in triplicate. The y-axis represents the mean 2ΔCT, and the error bars represent the standard error.
