| | Human PPARalpha Reporter Assay |
| Description: | The screening of test compounds for agonist or antagonist activities against human PPARα receptors was performed using a commercial kit, Human PPARα Reporter Assay System (Indigo Biosciences, Cat. #1B00111). This nuclear receptor assay system utilizes proprietary non-human mammalian cells engineered to provide constitutive, high-level expression of Human PPARα. Because these cells incorporate a PPARα-responsive luciferase reporter gene, quantifying expressed luciferase activity provides a sensitive surrogate measure of PPARα activity in the treated cells. The primary application of this reporter assay system is in the screening of test samples to quantify any functional activity, either agonist or antagonist, that they may exert against human PPARα. While this assay may be used to measure agonism, each of the Examples, infra, exhibits antagonism rather than agonism. Briefly, the reporter cells are dispensed into wells of the assay plate and then immediately dosed with test compounds. Following an overnight incubation, the treatment media are discarded and Luciferase Detection Reagent (LDR) is added. The intensity of light emission from the ensuing luciferase reaction provides a sensitive measure that is directly proportional to the relative level of PPARα activation in the reporter cells. |
