p53-Luc/EF1α-mCherry Reporter Cell Line - NIH3T3

The p53-Luc/EF1α-mCherry Reporter Cell Line - NIH3T3 is a genetically engineered mouse fibroblast cell line developed from the widely used NIH3T3 background. It contains a p53-responsive luciferase reporter system, in which luciferase expression is controlled by p53 response elements, together with an EF1α-driven mCherry fluorescent marker. The p53-Luc reporter enables quantitative monitoring of p53 transcriptional activity through luminescence, while mCherry fluorescence provides a convenient indicator of reporter-cell identity, transduction efficiency, and cell distribution. As a stable reporter model, it is suitable for experiments requiring consistent and reproducible assessment of p53 pathway activation.

This reporter cell line is primarily used to study p53 signaling, a key pathway involved in DNA damage responses, cell-cycle regulation, senescence, and apoptosis. Treatment with genotoxic agents, oxidative stressors, radiation, or pathway-modulating compounds can induce p53 activity, resulting in increased luciferase expression that can be measured with a luminescence assay. The system is therefore useful for screening compounds that activate or inhibit p53-dependent transcription, evaluating the biological effects of anticancer agents, and investigating mechanisms associated with tumor suppressor regulation. The mCherry signal supports complementary fluorescence-based observation, allowing researchers to monitor cell morphology, localization, and relative cell abundance during experiments. In addition, the line can be applied to pathway validation, toxicity studies, drug-response profiling, and high-throughput screening.
