Myc-Luc/EF1α-mCherry Reporter Cell Line - T24

The Myc-Luc/EF1α-mCherry reporter cell line (based on T24 cells) is a dual-labeled, engineered cellular tool derived from the human bladder transitional cell carcinoma T24 cell line. This model is specifically designed to quantitatively monitor the transcriptional activity of the c-Myc oncogene—a central regulator of cell cycle progression, metabolism, and apoptosis. The genetic architecture of this cell line incorporates a synthetic promoter consisting of multiple tandem c-Myc response elements (MREs) positioned upstream of a firefly luciferase gene. To enhance its utility, the cell line also constitutively expresses the fluorescent protein mCherry under the control of an EF1α promoter. This design provides a reliable internal reference, allowing for the normalization of luciferase signals against cell number, and facilitates long-term live-cell imaging. As these genetic cassettes are stably integrated into the genome, the cell line maintains consistent reporter performance over multiple passages, making it a robust platform for oncology research.

In terms of application, this reporter cell line is primarily used for high-throughput screening (HTS) to identify and validate inhibitors of the Myc signaling pathway. Given that Myc dysregulation is a hallmark of many aggressive cancers, this T24-based reporter line enables sensitive monitoring of drug-induced changes in Myc-mediated transcription via straightforward bioluminescence assays. Beyond drug discovery, it serves as an ideal system for functional genomics studies—such as those involving CRISPR-based gene knockout or RNA interference—aiding in the dissection of the complex regulatory networks that control Myc expression. Furthermore, the inclusion of the red fluorescent marker mCherry allows the cell line to be used in co-culture experiments or as a tracer in xenograft models, enabling the monitoring of tumor growth and reporter activity within a physiological context. By providing both quantitative readouts and visual tracking capabilities, this cell line streamlines the assessment of therapeutic efficacy and the underlying mechanisms of signal transduction.
