NFKB1 and neoplasm: We also observed an inverted miRNA phenotype, by NF‐κB inhibitor, in acidic bile‐treated HHK, demonstrating a significant decrease in expression ratios of “oncomirs” (P = .0114, one‐way ANOVA; by Kruskal‐Wallis) (Figure 5A‐a) and an increase in expression ratios of “tumour suppressor” miRNAs (with/without BAY 11‐7082), compared to control (Figure 5A‐b).
