Cell Line Name


Cell Line Description

The stable human mammary MCF7-derived reporter cell line called AREc32 contains copies of the rat Glutathione-S-transferase (GST) antioxidant response element (ARE) linked to a luciferase gene, such that the induction of the ARE results in luciferase activity. ARE is a transcriptional 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 investigate whether anticancer drugs can induce ARE-driven gene expression.

Culture Conditions

Cell Type


Subculture Routine

Split sub-confluent cultures (70-80%) 1:3 to 1:6 i.e. seeding at 2-4x10⁴ cells/cm²using 0.05% trypsin/EDTA solution. Cells are cultured at 37°C, in 95% air and 5% CO₂, and passaged every 3 to 4 days

Culture Medium

Dulbecco's Moodifies Eagle Medium (DMEM) with 2.5 mM Glutamax supplemented with 10% foetal bovine serum. Do not culture beyond 15 passages after revival

Growth Mode

GMO Status

Genetically Modified Organism Class 1 (GMO1)

Genetic Modification

Yes. The ARE-luciferase reporter plasmid was generated using the pGL3-promoter vector containing an SV40 promoter upstream of the firefly luciferase gene.

If use of this culture results in a scientific publication, it should be cited in the publication as: MCF7 AREc32 (ECACC 16071902).

Unless specified otherwise, at ECACC we routinely handle all of our cell lines at containment level 2 in accordance with the ACDP guidelines (Advisory Committee on Dangerous Pathogens) (UK). All cell cultures have the potential to carry as yet unidentified adventitious agents. It is the responsibility of the end user to ensure that their facilities comply with biosafety regulations for their own country. ACDP Guidance: Biological agents: Managing the risks in laboratories and healthcare premises.

The Culture Collections represent deposits of cultures from world-wide sources. While every effort is made to ensure details distributed by Culture Collections are accurate, Culture Collections cannot be held responsible for any inaccuracies in the data supplied. References where quoted are mainly attributed to the establishment of the cell culture and not for any specific property of the cell line, therefore further references should be obtained regarding cell culture characteristics. Passage numbers where given act only as a guide and Culture Collections does not guarantee the passage number stated will be the passage number received by the customer.

Cultures supplied by Culture Collections are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line.
