    MedChemExpress brm 014
    (A) Screen readout using smRNA-FISH with ERRFI1 -intronic and MYH9 -3’UTR probes to detect nascent transcription sites in fixed cells. (B) Screening workflow: sgRNAs targeting ∼1,100 genes are transfected in arrayed 384-well plates, followed by 72-hr knockdown, hormone depletion, dexamethasone treatment, and fixation for smFISH. Plates are imaged by spinning confocal microscopy (60X, 9 fields of view/well), and nuclear spots are quantified per cell via automated DAPI segmentation and spot detection. (C) 2D scatter plot of averaged Z-scores (2 replicates) for ERRFI1 (x-axis) and MYH9 (y-axis) nuclear spots, zeroed to the mean of negative controls (sgNEG, sgOR10A5). Hits classified into four categories: “common up” (n=8), “common down” (n=111), “MYH9-specific” (n=16), and “ERRFI1-specific” (n=72). (D) Representative smFISH images for each hit category alongside negative (sgNEG) and positive (sgNR3C1) controls. (E) STRING interaction network of “ERRFI1-specific” hits (left) and representative smFISH images for selected hits (right) (F) RT-qPCR measurement of nascent transcription (intron 1 primers) after 30-min pretreatment with triptolide (TPL; TFIIH <t>inhibitor),</t> <t>BRM-014</t> (BRM/BRG1 inhibitor), or Pevonedistat (MLN-4924; NEDD8-activating enzyme inhibitor), followed by 2-hr vehicle (left) or 100nM Dex (right) treatment.
