The involvement of caspase-3 and its failure in the induction of DNA fragmentation during erythropoiesis were investigated with TF-1 cells. During erythroid differentiation, caspase-3 activation and cleavage of caspase-3 substrates such as ICAD (inhibitor of caspase-activated DNase) were detected without concomitant phosphatidyl-serine (PS) externalization and DNA fragmentation. These observations are in contrast to our understanding that DNA is degraded by CAD (caspase-activated DNase) when ICAD is cleaved by caspase-3. Our study demonstrates that CAD is downregulated at the mRNA and protein level during the erythroid differentiation in TF-1 cells. This provides a mechanism for the first time how cells avoid DNA fragmentation with activated caspase-3.
