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

The Myc-Luc/EF1α-mCherry reporter cell line (based on U87MG) is a genetically engineered human glioblastoma model derived from the U87MG cell line. This cell line incorporates a reporter construct in which the Myc promoter drives the expression of firefly luciferase, enabling the quantitative monitoring of Myc transcriptional activity via bioluminescence. Additionally, an mCherry expression cassette—driven by the EF1α promoter—is integrated into the cells, serving as a constitutive fluorescent marker that facilitates the identification, visualization, and tracking of these modified cells. By combining a "pathway-responsive" luciferase readout with a stable red fluorescent signal, this dual-reporter system provides a practical and reliable platform for investigating Myc regulatory mechanisms within the context of glioblastoma.

This reporter cell line is primarily used to study the mechanisms that regulate Myc promoter activity and to assess the impact of genes, signaling pathways, chemical compounds, or biological stimuli associated with glioblastoma progression. It is well-suited for the high-throughput screening of small-molecule inhibitors or activators, assisting researchers in identifying candidate molecules capable of modulating Myc-driven transcriptional responses. The mCherry signal serves as an internal indicator of cell presence, transgene expression, and experimental consistency, while the luciferase assay allows for sensitive, quantitative measurement of promoter activity. Potential applications include drug discovery, target validation, the study of transcriptional regulation, cancer biology research, and the evaluation of combination therapeutic strategies. Given the widespread use of U87MG cells in glioblastoma research, this model can also be employed to examine cell proliferation, survival, migration, invasion, and therapeutic response, all while simultaneously monitoring Myc activity.
