The cell death was associated with activation of caspase-3 and cleavage of DNA repair enzyme poly ( ADP - ribose ) polymerase ,
Caspase-9 was activated significantly in HHV-6Ainfected cells ,
The cell death was associated with activation of caspase-3 and cleavage of DNA repair enzyme poly ( ADP - ribose ) polymerase , which is known to be an important substrate for activated caspase-3 .
Caspase-9 was activated significantly in HHV-6Ainfected cells , whereas caspase-8 was not activated obviously .
