The PCR profile consisted of an initial denaturation at 94uC for 5 min followed by 35 cycles of denaturation at 95uC for 30 sec, annealing at 55uC for 30 sec, and extension at 72uC for 45 sec, and final extension at 72uC for 10 min.Cloning of hP2 Promoter Linked Luciferase Gene ConstructsThe 1,108 bp fragment of the hP2 promoter was cloned from genomic DNA isolated from HepG2 cells using the hP2-forward primer (59-GGTACCACTACCTACTCAGAGACATCTGC-39; underline indicates a KpnI restriction site) and the hP2-reverse 1531364 primer (59-CTCGAGGTCCTCGCCGCCGCCTCTACC-39; underline indicates a XhoI restriction site). The PCR product was then ligated to the pGEM-T Easy vector (Promega) and sequenced. The clone with the correct sequence of the hP2 promoter was excised from the pGEM-T easy vector with KpnI and XhoI sites and ligated to the equivalent sites of the pGL3-basic vector (Promega) to generate a hP2-luciferase reporter construct.59-truncated hP2 promoter constructs comprising 985, 640, 365, 240, 114, and 41 nucleotides of the hP2 promoter were generated by PCR using a full length hP2 promoter-luciferase construct as a template. The forward primers Dovitinib (lactate) containing a KpnI site at their 59ends and the reverse primer containing an XhoI site at the 39-end were designed. The PCR products were then ligated into the pGEM-T Easy vector and sequenced. The correct sequences of 59truncated hP2 promoter were excised with KpnI and XhoI and ligated to the equivalent sites of the pGL3-basic vector. Primers used for cloning of 59-truncated hP2 promoters are shown in Table 1. For the construction of a 489 bp fragment of hP2 promoter, the promoter was generated by double digestion of the full length hP2 promoter-luciferase construct with NheI and XhoI. The 489 bp fragment of the hP2 promoter was then re-ligated into the NheI and XhoI site of the pGL3-basic vector.Figure 6. Transactivation of a WT 2365 human PC P2 luciferase reporter construct and its mutant by Sp1, Sp3, USF1 or USF2. WT 2365 hP2 or 2340/2315 hP2 constructs were co-transfected with an empty vector (pcDNA3) or a plasmid overexpressing Sp1, Sp3, USF1 or USF2 into the INS-1 832/13 cell line, and the luciferase activities measured. The luciferase activity was normalized to b-galactosidase activity and expressed as relative luciferase activity. Relative luciferase values obtained from co-transfecting cells with wild type (2365 hP2) or its mutant (2340/2315 hP2) and plasmid overexpressing Sp1, Sp3, USF1 or USF2 were presented as fold change relative to those obtained from those co-transfected with WT with empty vector (pcDNA3) which was arbitrarily set at 1. *p#0.01. doi:10.1371/journal.pone.0055139.gDistal Promoter 24786787 of the Human Pyruvate DMXAA biological activity CarboxylaseTable 1.
