Longevity & AgingCellular Senescence Pathway Reveals New Target for Aggressive Leukemia
Researchers have identified that a critical cellular senescence gene, p16INK4a, is suppressed in FLT3-ITD-positive acute myeloid leukemia (AML), a particularly aggressive blood cancer. Using patient datasets and mouse models, the team showed that low p16INK4a expression correlates with significantly worse survival outcomes. The FLT3-ITD mutation drives this suppression through a molecular chain involving STAT5A, E2F3, and EZH2 — allowing cancer cells to evade the normal cellular aging process that would otherwise halt tumor growth. Restoring or targeting this pathway offers a promising new therapeutic avenue for patients with refractory FLT3-ITD AML, a group with historically poor long-term prognosis.
