Berberine Effects On Nf Kappa B, Hif1a And Nfe2l2/Ap-1 Pathways In Hela Cells

Background: Berberine has multitudinous anti-cancer stem cells effects making it a highly promising candidate substance for the next-generation cancer therapy. However, berberine modes of action predispose it to significant side-effects that probably limit its clinical testing and application.Materials and Methods: HeLa cells were treated with two concentrations of berberine (30 and 100 mu M) for 24 hours to assess the functioning of the NFE2L2/AP-1, NF kappa B and HIF1A pathways using 22 RNAs expression qPCR-based analysis.Results: Berberine effects appeared to he highly dose-dependent, with the lower concentration being capable of suppressing the NF kappa B functioning and the higher concentration causing severe signaling side-effects seen in the HIF1A pathway and the NFE2L2 sub-pathways, and especially and more importantly in the AP-1 sub-pathway.Conclusion: The results of the study suggest that berberine has clinically valuable anti-NF kappa B effects however jeopardized by its side effects on the HIF1A and especially NFE2L2/AP-1 pathways, its therapeutic window phenomenon and its cancer type-specificity. These, however, may be ameliorated using the cocktail approach. provided there is enough data on signaling effects of berberine.
