PTGS1 and Barrett esophagus: Table 2 shows that in BE samples, the mRNA expression of IFNGR1, SOCS3, TIMP1, TNFRSF10B, TMEM2, IL1B, FZD5, SOX4, SOX9, PTGS2 was significantly increased (p < 0.05, logFc > 1) in at least one out of three datasets, whereas mRNA expression of IL1RN, IL1A, NFKBIL1, SOX15 and PTGS1 was significantly decreased in comparison to squamous epithelium (p < 0.05, logFC < −1).
