In contrast, HHPC and HHK exposed to acidic bile with NF‐κB inhibitor demonstrated lower levels of “oncomirs” and significantly higher levels of “tumour suppressor” miRNAs, compared to those cells exposed to acidic bile without NF‐κB inhibitor (P < .05) (Figures 2 and 3) (one‐way ANOVA; by Friedman). Here, NFKB1 is linked to neoplasm.
