Molecular Mechanisms of Senescence and Implications for the Treatment of Myeloid Malignancies

Cancers (Basel). 2021 Feb 4;13(4):612. doi: 10.3390/cancers13040612.


Senescence is a cellular state that is involved in aging-associated diseases but may also prohibit the development of pre-cancerous lesions and tumor growth. Senescent cells are actively secreting chemo- and cytokines, and this senescence-associated secretory phenotype (SASP) can contribute to both early anti-tumorigenic and long-term pro-tumorigenic effects. Recently, complex mechanisms of cellular senescence and their influence on cellular processes have been defined in more detail and, therefore, facilitate translational development of targeted therapies. In this review, we aim to discuss major molecular pathways involved in cellular senescence and potential therapeutic strategies, with a specific focus on myeloid malignancies.

Keywords: SASP; leukemia; myelodysplastic syndrome; myeloproliferative neoplasms; senescence; senolytics.
