We observed that NF‐κB inhibitor induced an inverted miRNA phenotype of “oncomirs” and particularly of “tumour suppressor” miRNAs in acidic bile‐treated normal human hypopharyngeal cells, HHPC (Figure 4) and HHK (Figure 5), compared to control, demonstrating significant changes of the expression ratios (with/without BAY 11‐7082) between acidic bile and control groups (P = .0442 and P = .0139, respectively, by Friedman). Here, NFKB1 is linked to neoplasm.
