APR_HepG2_StressKinase_24hr, is one of 10 assay component(s) measured or calculated from the APR_HepG2_24hr assay. It is designed to make measurements of enzyme activity, a form of enzyme reporter, as detected with fluorescence intensity signals by HCS Fluorescent Imaging technology.Data from the assay component APR_HepG2_StressKinase_24hr was analyzed into 2 assay endpoints. 
This assay endpoint, APR_HepG2_StressKinase_24h_up, was analyzed in the positive fitting direction relative to DMSO as the negative control and baseline of activity. 
Using a type of enzyme reporter, measures of protein for gain-of-signal activity can be used to understand the signaling at the pathway-level as they relate to the gene . 
Furthermore, this assay endpoint can be referred to as a primary readout, because this assay has produced multiple assay endpoints where this one serves a signaling function. 
To generalize the intended target to other relatable targets, this assay endpoint is annotated to the "cell cycle" intended target family, where the subfamily is "stress response". Is this molecule effective to this assay?
