WebChromosomal DNA in apoptotic cells is cleaved cell-autonomously into 180-bp nucleosomal units by CAD. Although CAD-null cells do not undergo DNA fragmentation during apoptosis, their DNA is digested by DNase II in macrophage lysosomes after the dead cells are engulfed ( Kawane et al., 2003; McIlroy et al., 2000 ). WebFeb 16, 2010 · One hallmark of caspase-mediated apoptosis that may also propel cell differentiation is chromatin alteration and DNA damage/fragmentation.
