Abstract

Background: The mechanisms by which IFNs generate antineoplastic responses remain to be defined. Results: Type I IFN treatment results in activation of the Mnk/eIF4E pathway in Jak2V617F-transformed cells, and this activation is required for the antineoplastic effect. Conclusion: Mnk kinases are essential for the antineoplastic effects of IFN. Significance: This study provides evidence for a key mechanism mediating the effects of IFNs in malignant MPN precursors.
