title: Construction and transfection of a ribozyme targeting human caspase-3.
abstract: Caspase-3 is a key executioner cysteine protease involved in programmed cell death or apoptosis. A ribozyme to human caspase-3 was designed, tested by in vitro cleavage, and transfected into a drug-resistant variant (DLKP-A5F) of a human lung carcinoma cell line (DLKP). By both stable and transient transfection, this ribozyme was shown to be effective at down-regulating human caspase-3 mRNA and protein levels.
