AP1-Luc/EF1α-mCherry Reporter Cell Line - SH-SY5Y

AP1-Luc/EF1α-mCherry Reporter Cell Line – SH-SY5Y is a human neuroblastoma-derived reporter cell line engineered for sensitive monitoring of activator protein-1 (AP-1) transcriptional activity. The cells contain a firefly luciferase reporter driven by AP-1-responsive elements, enabling quantitative measurement of AP-1 pathway activation through a convenient luminescence readout. In parallel, constitutive expression of mCherry under the human EF1α promoter provides a stable fluorescent marker for cell identification, morphology assessment, and normalization of cell number or transfection-independent variations. SH-SY5Y cells are widely used as an in vitro neuronal model because they exhibit neuroblast-like characteristics and can be differentiated toward a neuron-like phenotype under appropriate culture conditions. This dual-reporter design combines pathway-specific functional analysis with continuous fluorescent tracking in a biologically relevant human neuronal cell background.

The AP1-Luc/EF1α-mCherry Reporter Cell Line – SH-SY5Y is suitable for drug discovery, pathway profiling, and mechanistic studies involving AP-1-regulated signaling. AP-1 activity can be induced by stimuli associated with MAPK, JNK, ERK, p38, PKC, oxidative stress, inflammatory mediators, growth factors, and cellular stress responses. The cell line can therefore be used to screen small molecules, biologics, natural products, or genetic perturbations for their ability to activate or inhibit AP-1 signaling. It is particularly valuable in neuroscience research focused on neuroinflammation, oxidative injury, neuronal stress, neurotoxicity, and signaling events associated with neurodegenerative disorders. Luciferase activity provides a sensitive, scalable endpoint compatible with multiwell assay formats, while mCherry fluorescence supports live-cell visualization, cell confluence monitoring, and assay quality control.
