IFNB1 and infection: Unlike IFN-β, the level of produced IL-6 markedly increased up to 400 pm/ml in miR-141 transduced cells at 24 h post-infection, while significantly decreased in cells transfected with the inhibitor antagonist miR-141, indicating the role of miR-141 in IL-6 signaling pathway in infected cells (Fig. 6B).
