Product description: The stable human mammary MCF7 AREc32 reporter cell line contains copies of the rat GST antioxidant response element (ARE) linked to a luciferase reporter gene, such that the induction of the ARE results in luciferase activity. ARE is a transcriptional cis-regulatory element involved in the activation of genes coding for a number of antioxidant proteins and enzymes that work in concert to protect tissues from oxidative insults. This cell line can be used to evaluate how potential anti-cancer agents modulate ARE-mediated antioxidant pathways and identify antioxidant proteins that may serve as potential therapeutic targets.
Conditional: Yes
Production details: The ARE-luciferase reporter plasmid was generated using the pGL3-promoter vector containing an SV40 promoter upstream of the firefly luciferase gene. They differ in the number of copies of ARE sequences that have been inserted, in head-to-tail orientation, through Nhe I & Xho I restrictionsites upstream of the promoter-luc+ transcriptional unit. A plasmid was made containing eight copies of the ARE (5′-GTGACAAAGCA-3′, with the minimal functional sequence underlined) present in both rat GSTA2 and mouse gsta1; called pGL-8xARE. A linker with the sequence of 5′-CCC-3′ and 5′-GGG-3′ on the opposite strand was placed between individual cis-elements.pGL-8xARE, was stably transfected into MCF7 cells using the calcium phosphate method. Transfected cells were selected using 0.8 mg/mL G418 in the media for 3 to 4 weeks. The G418-resistant clones were isolated and screened by measuring their basal and inducible (obtained by treatment with 50 Amol/L t-BHQ) luciferase activities as described above. Positive clones, which showed low background and high inducible luciferase activity, were passaged and maintained in growth medium containing 0.8 mg/mL G418.
