Figure 1. PTPRZ1 luciferase promoter constructs showing the location of the potential hypoxia response elements (HRE) and Ets binding sequences (EBS).

Figure 1

Each HRE is denoted as a square and each EBS as a plus sign. The TATA box and the ATG start site are indicated in the PTPRZ1-250 promoter. Each promoter construct extends 57 bp into the PTPRZ1 coding region prior to the luciferase (LUC) sequence except for the PTPRZ1-250 promoter, which stops at the ATG. The HRE consensus sequences and direction of each HRE are also indicated. The core HRE sequences are: HRE1, CCGTG; HRE2, CACGC; HRE3, CACGC; HRE4, CACGCACG; HRE5, CACGG.
