1 Caspases-8, -9 and -3 activities were increased in irradiated hepatocytes and downregulation of apoptosis by IkappaB antisense oligonucleotides was mediated by suppression of caspases-9 and -3 activation but not of caspase-8 activation, suggesting that radiation-induced sensitization of hepatocytes to TNF-alpha-mediated apoptosis additionally requires changes upstream of caspase-8 activation. Oligonucleotides caspase 8 Homo sapiens
