Bcl-xL and Bcl-2 promoter-EGFP reporter vectors ended up created as follows. Bcl-xL promoter of 400 bp (positions -396 to +33 relative into the transcriptional get started web site) was PCR-amplified from human genomic DNA, cloned into BglII/PstI web page upstream of the EGFP coding gene of pEGFP-1 vector (Clontech, Palo Alto, CA) and designated as XL-400-EGFP. Bcl-2 promoter of 1840 bp (positions
