Kits are offered in different assay formats to accommodate researchers’ needs: 3x 32, 1x 96, and 1x 384 assay formats for screening small numbers of test compounds, as well as custom bulk reagents for HTS applications. Assay systems are all inclusive, providing reporter cells, optimized growth media, media for diluting test compounds, a positive-control agonist, luciferase detection reagent, a white assay plate, a detailed protocol, and a protocol quick guide. All kits are shipped on dry ice.
PPAR Reporter Cells are prepared using INDIGO’s proprietary CryoMite™ process. This cryo-preservation method yields high cell viability post-thaw, and provides the convenience of immediately dispensing healthy, division-competent reporter cells into assay plates. There is no need for intermediate spin-and-wash steps, viability determinations, or cell titer adjustments.
The principle application of this assay product is in the screening of test samples to quantify functional activities, either agonist or antagonist, that they may exert against the human peroxisome proliferator-activated receptor alpha. This kit product is an all-inclusive assay system that includes, in addition to PPAR Reporter Cells, two optimized media for use during cell culture and (optionally) in diluting the test samples, a reference agonist, Luciferase Detection Reagent, a cell culture-ready assay plate, and a detailed protocol.
Bulk assay reagents can be custom manufactured to accommodate any scale of HTS. Please inquire.

These PPARα Reporter Assay Systems utilize non-human mammalian cells engineered to express human PPARA, commonly referred to as PPARα.
Peroxisome proliferator-activated receptor alpha (PPARα), also known as NR1C1, is a nuclear receptor protein encoded by the PPARA gene. PPAR ligands, whose names derived from their effect on inducing an increase in the size and number of peroxisomes, include hypolipidemic drugs, herbicides, leukotriene antagonists, and plasticizers. Peroxisomes are subcellular organelles found in plants and animals that contain enzymes for respiration and for cholesterol and lipid metabolism. The action of peroxisome proliferators is thought to be mediated via specific receptors, called PPARs, which belong to the steroid hormone receptor superfamily. PPARs affect the expression of target genes involved in cell proliferation, cell differentiation and in immune and inflammation responses. Three closely related subtypes (alpha, beta/delta, and gamma) have been identified. Multiple alternatively spliced transcript variants have been described for PPARα gene, although the full-length nature of only two has been determined.

The primary application of INDIGO’s cell-based nuclear receptor assays are to quantitatively assess the bioactivity of a test compound as an agonist (activator) or antagonist (inhibition of an agonist response) of a given receptor. Service assays include a positive control reference compound and ‘vehicle’ control for every experiment. A formal study report and all data files are provided to the client upon completion of the study.

To initiate a Service Study, download and complete all fields of the Excel worksheet “Service Work Order" then submit the electronic file to INDIGO Customer Service.
Adverse Outcome Pathway on antagonist binding to PPARa leading to body-weight loss
ABSTRACT The present AOP describes antagonistic chemical binding to the peroxisome proliferator-activated receptor α (PPARα), resulting in preferential binding a co-repressor to the overall PPARα signalling complex causing a chain of events that includes: antagonism of PPARα nuclear signalling, decreased transcriptional expression of PPARα-regulated genes that support energy metabolism, inhibited metabolic energy production (decreased fattyRead More
Discovery of potent and selective PPARα/δ dual antagonists and initial biological studies Author links open overlay panel
ABSTRACT We previously published on the design and synthesis of novel, potent and selective PPARα antagonists suitable for either i.p. or oral in vivo administration for the potential treatment of cancer. Described herein is SAR for a subsequent program, where we set out to identify selective and potent PPARα/δ dual antagonist molecules. Emerging literature indicates that bothRead More
Comparative Evaluation of Gemcabene and Peroxisome Proliferator–Activated Receptor Ligands in Transcriptional Assays of Peroxisome Proliferator–Activated Receptors: Implication for the Treatment of Hyperlipidemia and Cardiovascular Disease
ABSTRACT Gemcabene, a late-stage clinical candidate, has shown efficacy for LDL-C, non-HDL cholesterol, apoB, triglycerides, and hsCRP reduction, all risk factors for cardiovascular disease. In rodents, gemcabene showed changes in targets, including apoC-III, apoA-I, peroxisomal enzymes, considered regulated through peroxisome proliferator–activated receptor (PPAR) gene activation, suggesting a PPAR-mediated mechanism of action for the observed hypolipidemic effects observedRead More
Structure-guided evolution of a 2-phenyl-4-carboxyquinoline chemotype into PPARα selective agonists: New leads for oculovascular conditions
ABSTRACT Small molecule agonism of PPARα represents a promising new avenue for the development of non-invasive treatments for oculovascular diseases like diabetic retinopathy and age-related macular degeneration. Herein we report initial structure–activity relationships for the newly identified quinoline-based PPARα agonist, Y-0452. Preliminary computational studies led to the hypothesis that carboxylic acid transposition and deconstruction ofRead More

Sedaxane—Use of Nuclear Receptor Transactivation Assays, Toxicogenomics, and Toxicokinetics as Part of a Mode of Action Framework for Rodent Liver Tumors
ABSTRACT Experimental data demonstrate a mode of action (MOA) for liver tumors in male rats and mice treated with sedaxane that starts with activation of CAR, followed by altered expression of CAR-responsive genes, increased cell proliferation, and eventually clonal expansion of preneoplastic cells, leading to the development of altered foci and tumors. This MOA isRead More
GPR40 partial agonist MK-2305 lower fasting glucose in the Goto Kakizaki rat via suppression of endogenous glucose production
ABSTRACT GPR40 (FFA1) is a fatty acid receptor whose activation results in potent glucose lowering and insulinotropic effects in vivo. Several reports illustrate that GPR40 agonists exert glucose lowering in diabetic humans.
