Figure Lengend Snippet: Schematic illustration of FHF treatment for MPNs. FHF treatment inhibits the JAK2/STAT3 and NF-κB signaling pathways. This suppresses the expression of pro-inflammatory cytokines and cell proliferation. On the other hand, FHF promotes cellular senescence by activating the p53/p21 signaling pathway.
