In a new paper in Cell Research, Ji et al. find that transcription
factor-instigated opening of chromatin, during cell reprogramming, can be sensed
by the Baf60b-containing chromatin remodeling complex, which then activates the
ATM-p53 pathway, leading to cell death. These findings from reprogramming studies
unveil what I term a "chromatin remodeling checkpoint" whereby extensive,
inappropriate chromatin opening events lead to cell elimination, thus preventing
cell fate conversion that might occur upon tissue damage; if unchecked, such
conversion could lead to metaplasia and cancer.
