ARE-Luc/EF1α-mCherry Reporter Cell Line - U87MG

ARE-Luc/EF1α-mCherry Reporter Cell Line - U87MG is a genetically engineered human glioblastoma cell line derived from U87MG cells. It contains an antioxidant response element (ARE)-driven luciferase reporter system for monitoring the transcriptional activity of the Nrf2/ARE signaling pathway, together with an EF1α promoter-driven mCherry fluorescent marker for stable cell identification and experimental tracking. The luciferase signal reflects changes in ARE-dependent gene expression and can be quantified using a luminescence-based assay, while mCherry fluorescence provides a convenient visual indicator of cell presence, morphology, and transduction stability. This dual-reporter design combines sensitive pathway analysis with straightforward fluorescence monitoring in a well-established glioblastoma cellular background.

This reporter cell line is primarily intended for research on the Nrf2/ARE pathway, oxidative stress, antioxidant responses, and cytoprotective mechanisms in glioblastoma cells. It can be used to evaluate compounds that activate or inhibit ARE-mediated transcription, screen potential antioxidants and electrophilic agents, and investigate the molecular effects of environmental stressors, pharmaceutical candidates, and natural products. The system is also useful for studying drug-induced oxidative responses, cellular defense mechanisms, and signaling interactions associated with tumor biology. In high-throughput screening, luciferase measurements enable rapid and quantitative comparison of pathway activity across multiple treatment conditions, whereas mCherry fluorescence supports cell number estimation, assay quality control, and visualization of cellular distribution. Researchers may further apply this model to mechanism-of-action studies, preliminary toxicity evaluation, combination treatment assessment, and validation of Nrf2-related targets.
