CHK2-USP37 Axis Stabilizes FOXO4 to Sustain Senescence and Evade Apoptosis
Key Highlights
Cell Biology · Aging
This study identifies a novel CHK2-USP37 signaling axis that stabilizes the transcription factor FOXO4, thereby sustaining the survival of apoptosis-resistant senescent cells. Researchers demonstrated that USP37 deubiquitinates FOXO4, preventing its degradation and allowing senescent cells to evade programmed cell death. For your interests in aging mechanisms and apoptosis, this finding reveals a molecular vulnerability in senescent cell persistence that could be targeted to clear dysfunctional cells in aging tissues, including the ovary, and offers a potential therapeutic avenue for age-related diseases.
