| | Dual-Cell beta-Catenin Reporter Assay |
| Description: | Mouse L cells transfected to constitutively produce biologically active murine Wnt-3a, referred to as L-Wnt cells, were purchased from the American Type Culture Collection, ATCC, Manassas, Va. (ATCC). These cells were cultured in DMEM supplemented with 10% FCS (Gibco/Invitrogen, Carlsbad, Calif.), 1% geneticin and 1% sodium pyruvate (Sigma) at 37° C. with 5% CO2. The cells were seeded into 96 well plates and treated with serial dilutions of compound diluted to 0.1% DMSO concentration. After 24 hours, cell supernatants were transferred to a 96 well plate previously seeded with Leading Light Wnt Reporter Cells, stably transfected with a luciferase gene under control of Wnt pathway response elements. After a further 24 hours, cells are treated with One-glo luciferase assay system (Promega, Madison, Wis.) and the luminescent signal read by envision. The IC50 of the compound is determined as the concentration that reduces the induced luciferase signal to 50% of the DMSO control. |
