Abstract:
:We prepared a cleavage site-directed antiserum against Caspase-3 (anti-p20/17), which reacts with the p20/17 fragment (p20/17) activated by cleavage but not proCaspase-3 (p32), and examined the relationship between the activation of Caspase-3 and apoptosis. We identified p20/17-positive cells where cell death occurs naturally: interdigits of the forelimbs, small intestine epithelium, thymus, trigeminal ganglia, and dorsal root ganglia of mouse embryos. Withdrawal of nerve growth factor induced the appearance of p20/17-positive cells with DNA fragmentation in the culture of dorsal root ganglia neurons, while DNA fragmentation was detected in both p20/17-positive and -negative neurons in dorsal root ganglia of mouse embryos. These results suggest that not only activation of Caspase-3 but also other molecular mechanism play a role in the naturally occurring dorsal root ganglia apoptosis. Cleavage site-directed antisera against Caspases will be useful for the analysis of the molecular mechanism of naturally occurring apoptosis during development.
