Exploiting cellular senescence in hematologic malignancies

Cellular Senescence is characterized by stable cell cycle arrest and major changes in cell morphology and physiology. Accumulating evidence indicates that senescence-associated phenotypic alterations in blood cells drive the initiation and progression of hematologic malignancies. Therefore, we reviewed the phenotypes associated with cellular senescence and the regulatory mechanisms of cellular senescence in hematological malignancies. Notably, chemical induction of cellular senescence and selectively elimination of senescent cells can effectively inhibit tumor cell proliferation and enhance the efficacy of chemotherapy. This review also discusses the role of cellular senescence in the treatment of hematological malignancies, providing an in-depth understanding of the role of cellular senescence as a double-edged sword in cancer biology.
