We conclude , therefore , that in the absence of E1A , E4orf4 is sufficient by itself to trigger a p53 - independent apoptosis pathway that may operate independently of the known zVAD - inhibitable caspases , and that may involve an as yet uncharacterized mechanism .
 GENE: E1A; GENE: E4orf4; GENE: p53; GENE: caspases
