STAT3-Luc/EF1α-mCherry Reporter Cell Line - U87MG

The STAT3-Luc/EF1α-mCherry reporter cell line (based on U87MG) is a genetically engineered human glioblastoma model derived from the U87MG cell line. It incorporates a luciferase reporter system driven by STAT3-responsive elements, enabling the monitoring of JAK/STAT3 signaling pathway activation via bioluminescence. Additionally, the cell line constitutively expresses the fluorescent protein mCherry under the control of the EF1α promoter, providing a stable fluorescent marker for cell identification, visualization, and normalization of experimental data. By integrating both bioluminescent and fluorescent detection into a single model, this reporter cell line offers a convenient and sensitive platform for studying STAT3 transcriptional activity within the context of glioblastoma cells.

The STAT3-Luc/EF1α-mCherry reporter cell line (based on U87MG) is suitable for a wide range of applications, including the study of pathway activation, inhibitor screening, drug discovery, and the investigation of mechanisms of action. Researchers can stimulate the cells with cytokines or other relevant factors to assess the status of the STAT3 signaling pathway; the model can also be used to evaluate the efficacy of small-molecule drugs, biologics, or genetic interventions designed to inhibit or enhance this pathway. Luciferase assays provide quantitative readouts, making them ideal for high-throughput screening, dose-response analysis, and compound comparison, while mCherry fluorescence facilitates cell tracking, assessment of transfection efficiency, microscopic imaging, and experimental quality control. Furthermore, this model can be employed to explore the regulatory relationship between the STAT3 signaling pathway and glioblastoma-associated phenotypes, such as cell proliferation, survival, migration, and therapeutic resistance. With its stable reporter gene expression and compatibility with various microplate-based assay formats, this cell line helps enhance experimental consistency and reduces the need for repeated transient transfections.
