To validate the pCCL-MUC5ACPromoter-FLuc-CMV-RLuc-dsRed2 (henceforth, “MUC5AC reporter”) construct (Fig. 3A), we transduced OE-19 cells, an esophageal adenocarcinoma cell line that was identified as expressing MUC5AC in the Human Protein Atlas cell line database (https://www.proteinatlas.org/). This evidence concerns the gene MUC5AC and esophageal adenocarcinoma.
