Bcl-xL and Bcl-2 promoter-EGFP reporter vectors have been made as follows. Bcl-xL promoter of four hundred bp (positions -396 to +33 relative on the transcriptional commence internet site) was PCR-amplified from human genomic DNA, cloned into BglII/PstI web page upstream on the EGFP coding gene of pEGFP-1 vector (Clontech, Palo Alto, CA) and specified as XL-400-EGFP. Bcl-2 promoter of 1840 bp (pos
