Figure 8

Transcriptional activity of the IAP upstream −186 to −167 element. A. Schematic representation of CAT constructs with the TK promoter alone, or with four copies of the −186/−167 oligonucleotide cloned upstream of the TK promoter (arrows indicate orientation of oligonucleotide). B. CAT assay of constructs 1 and 2 shown in A transfected into either F9 (lanes 1 and 2, respectively) or PYS-2 (lanes 3 and 4, respectively) cells. The number of independent transfection experiments with each construct that yielded similar results is shown in parentheses in A. C. Schematic representation of the IAP −186 to −167 region, with features of the IAP LTR as described in Figure 1. The boxed IUE sequence represents the IUE as described in the text.
