Conversely, genes significantly enriched in CT1/2 included innate immune response genes (BPIFB1, PELI3), fractalkine (CX3CL1), genes related to mucosal epithelial integrity (TFF3, CLDN10, MUC5B, LAMB1, RIPK4), genes related to neoplastic invasion (CTSK, KLK11, UCA1), and few related to tumor suppression (S100A14). This evidence concerns the gene BPIFB1 and neoplasm.
