To investigate if chronic exposure of murine HM to weakly acidic bile can deregulate cancer-related miRNA phenotype, we performed miRNA analysis, by reverse transcription and qPCR, for a panel of NF-κB related “oncomirs” and “tumor suppressor” miRNAs, previously linked to acidic bile-induced hypopharyngeal carcinogenesis [11,12,14,16,17,18]. Here, NFKB1 is linked to cancer.
