During aging, transcriptional programs of cell identity are partially eroded, reducing cellular fitness and resilience. Patrick et al. unveil a general mechanism for this process that consists of the progressive loss of transcription factor AP-1 from cell identity enhancers and its relocation by competition to stress-response elements.
在衰老过程中,细胞身份的转录程序部分被破坏,降低了细胞的适应性和弹性。Patrick 等人揭示了这一过程的一般机制,即转录因子 AP-1 逐渐从细胞身份增强子中丢失,并通过竞争重新定位到应激反应元件。
