BioAssay: AID 743140

qHTS assay to identify small molecule agonists of the peroxisome proliferator-activated receptor gamma (PPARg) signaling pathway: Summary

The peroxisome proliferator-activated receptors (PPARs) are lipid-activated transcription factors of the nuclear receptor superfamily with three distinct subtypes namely PPAR alpha, PPAR delta (also called PPAR beta) and PPAR gamma (PPARg). All these subtypes heterodimerize with Retinoid X receptor (RXR) and these heterodimers regulate transcription of various genes. PPAR-gamma receptor more ..

Tox21 Assay Overview:

The peroxisome proliferator-activated receptors (PPARs) are lipid-activated transcription factors of the nuclear receptor superfamily with three distinct subtypes namely PPAR alpha, PPAR delta (also called PPAR beta) and PPAR gamma (PPARg). All these subtypes heterodimerize with Retinoid X receptor (RXR) and these heterodimers regulate transcription of various genes. PPAR-gamma receptor (glitazone receptor) is involved in the regulation of glucose and lipid metabolism. To identify the compounds that activate PPAR-gamma signaling, GeneBLAzer PPAR gamma UAS-bla HEK293H cell line (Invitrogen, Carlsbad, CA, USA) containing a beta-lactamase reporter gene under control of the control of an upstream activator sequence (UAS) stably integrated into HEK293H cells was used to screen Tox21 compound library. The compounds were also tested for auto fluorescence that may interfere with the biological target readout resulting in potential false positives and/or negatives.
Protocol
Please refer to other AIDs 743094, 720687, 720685, 720678 and 720681, for detailed assay protocols.
Comment
This summary is written for the purposes of summarizing the compound activities from the project combining the results from both the PPARg agonist mode assay (AID 743094) and auto fluorescence counter screens (AIDs 720687, 720685, 720678 and 720681). For all inactive compounds, PUBCHEM_ACTIVITY_SCORE is 0. Active compounds have PUBCHEM_ACTIVITY_SCORE between 40 and 100. Potency and efficacy were used for determining relative score. Inconclusive compounds have PUBCHEM_ACTIVITY_SCORE between 5 and 30 determined by phenotype.

Disclaimer:

Although all reasonable efforts have been made to ensure the accuracy and reliability of the data, caution should be exercised when interpreting the results as artifacts are possible from nonspecific effects such as assay signal interference. The curve fitting and activity calls presented here are based on the NCATS analysis methods. Alternative analysis methods and interpretations of the data are available at EPA (http://actor.epa.gov) and NTP (http://tools.niehs.nih.gov/cebs3/ui/).
