Details for Assay 13: TOX21_Aromatase_Inhibition (ToxCast assay endpoint Aeid 767)

Description
TOX21_Aromatase_Inhibition is one of one assay component(s) measured or calculated from the TOX21_Aromatase_Inhibition assay. It is designed to make measurements of luciferase induction, a form of inducible reporter, as detected with bioluminescence signals by CellTiter-Glo Luciferase-coupled ATP quantitation technology. Changes to bioluminescence signals produced from an enzymatic reaction involving the key substrate [One-Glo] are indicative of changes in transcriptional gene expression due to modulation of the human cytochrome P450, family 19, subfamily A, polypeptide 1 [GeneSymbol:CYP19A1 | GeneID:1588 | Uniprot_SwissProt_Accession:P11511]. TOX21_Aromatase_Inhibition is a cell-based, single-readout assay that uses MCF-7, a human breast cell line, with measurements taken at 24 hours after chemical dosing in a 1536-well plate.
