DUSP1 and melanoma: Promising results in this context come from a study by Kundu and co-workers, who demonstrated that by combining the interferon-α2b (IFN-α2b) with a new selective MKP1 inhibitor, tyrosine phosphatase inhibitor-3 (TPI-3), it is possible to obtain better results than those achieved with IFN-α2b or TPI-3 alone in inhibiting melanoma growth both in vitro and in a xenograft nude mice model.
