AP1-Luc/EF1α-mCherry Reporter Cell Line - HeLa

AP1-Luc/EF1α-mCherry Reporter Cell Line - HeLa is a stable human cervical cancer cell line engineered to support sensitive monitoring of activator protein-1 (AP-1) signaling. The reporter construct contains AP-1 response elements driving firefly luciferase expression, enabling quantitative measurement of AP-1 transcriptional activity through a luminescence-based assay. In parallel, mCherry is constitutively expressed under the EF1α promoter, providing a robust fluorescent marker for cell identification, visualization, and normalization of cell number or transfection-related variability. AP-1 is a dimeric transcription factor complex mainly composed of JUN, FOS, ATF, and MAF family members. It serves as an important downstream effector of multiple signaling pathways, including MAPK/ERK, JNK, p38, protein kinase C, and cytokine-mediated pathways.

This reporter cell line can be used to investigate compounds, biologics, cytokines, growth factors, and environmental stimuli that regulate AP-1-dependent gene expression. Following treatment, AP-1 pathway activation or inhibition can be determined by measuring luciferase activity, while the EF1α-mCherry signal supports fluorescence imaging, cell tracking, and assessment of relative cell abundance. The model is suitable for screening anti-inflammatory agents, kinase inhibitors, oxidative stress modulators, and oncology drug candidates targeting MAPK- or AP-1-associated signaling networks. It may also be applied in studies of inflammation, cell proliferation, apoptosis, tumor progression, viral infection, and stress responses. In high-throughput formats, AP1-Luc/EF1α-mCherry Reporter Cell Line - HeLa provides a convenient dual-readout platform for identifying pathway modulators and distinguishing specific AP-1 effects from nonspecific changes caused by cytotoxicity or reduced cell viability.
