The CellSensor® Gli-bla NIH 3T3 Cell Line contains a beta-lactamase reporter gene under control of the Gli response element stably integrated into NIH 3T3 cells. This cell line is a clonal population isolated by flow cytometry in response to the mouse sonic hedgehog (mShh) ligand. This cell line has been tested for assay performance under variable conditions, including DMSO concentration, cell number, stimulation time, and substrate loading time, as well as validated for Z'-factor and EC50 concentrations of Shh. Additional data using known inhibitors or activators of the pathway have also been obtained. The morphogenic Shh induces proliferation of neuronal precursor cells in the developing cerebellum and other tissues. Proliferative signaling by Shh is involved in the development of cancer, including specific brain and skin cancers such as basal cell carcinomas. Signaling takes place through a Patched (PTC-1)/Smoothened (SMO) Receptor complex. The binding of the Shh ligand to PTC-1 releases the inhibitory effect of PTC-1 on SMO, which in turn leads to sonic hedgehog pathway activation of the Gli transcription factor to induce downstream gene expression.
