All three compounds were able to induce luciferase expression, demonstrating their ability to overcome Bach1 repression of HMOX E2 - dependent transcription (Figure 6C).
Nonetheless, CDDO - Me and HPP - 1014 still were able to activate HMOX1 E2 - dependent luciferase expression in the presence of mutant Bach1 proteins, indicating that the CP motifs in Bach1 are not critical for efficient derepression of Bach1 by an electrophile (Figure 6D).
Expression of HMOX1 E2 - dependent luciferase expression was determined in HepG2 cells co-transfected with an HMOX1 E2 - dependent reporter plasmid and a plasmid expressing FLAG - tagged wildtype Bach1 (Figure 6A).
Luciferase expression was markedly lower in cells expressing Bach1, indicating effective repression of HMOX1 E2 - dependent transcription by Bach1 (Figure 6B).
In these assays, both wild - type Bach1 and FLAG - hBach1 - AP4 - 7 efficiently repressed basal levels of luciferase expression.
In contrast, the ability of both CoPP and HPP - 4382 to induce HMOX1 E2 ARE - dependent luciferase expression in the presence of the mutant Bach1 protein was sharply inhibited.
When compared to unfractionated hu - PBMCs, the CD8 + - depleted hu - PBMC recipients show similar reductions in luciferase expression following IL - 15 superagonist treatment.
When spleens from infected mice were examined for sustained control of infection at later time points, however, luciferase expression had rebounded.
(11) To more directly test for defects in Wnt signaling, CAST / EiJ and C57BL / 6J WT and mTERT — / — embryonic fibroblasts were transfected with a luciferase reporter plasmid with a Wnt3a ligand; luciferase expression was indistinguishable between WT and mTERT — / — cells.
Cells were transfected with 320 ng pGL3 luciferase expression construct containing the 3 ′ UTR of human APC, 40 ng pGL4.74 hRLuc / TK Renilla luciferase vector (Promega, Fitchburg, WI), and 25 nM hsa - miR - 142 precursor or negative control precursor (Ambion).
