NF-κB-dependent GR cistrome redistribution recruits GR to inflammatory genes but correlates with lesser glucocorticoid-mediated repression
Bibliographic record
Abstract
While ligand-activated glucocorticoid receptor (GR) binds DNA to activate transcription, glucocorticoids, including budesonide, reduce inflammatory gene expression, yet recruit GR to many such gene loci. In epithelial cells, the inflammatory cytokine, interleukin-1β (IL1B), activates nuclear factor (NF)-κB to induce gene expression, and co-treatment with budesonide produces nanoscale GR-RELA nuclear co-localization. Such co-stimulation orchestrated reciprocal genome-wide redistribution of GR- and RELA-binding regions (GBRs and RBRs, respectively) relative to each mono-treatment to produce widespread GBR-RBR overlap. This correlated with increased RNA polymerase-2 presence and required NF-κB for GR cistrome remodeling. Mapping transcription start sites to the nearest GBR or RBR each revealed associations with upregulated, but not repressed, genes. Importantly, RBR proximity to budesonide-upregulated genes and GBR proximity to IL1B-upregulated genes correlated with attenuated repression on co-treatment. As this occurred on a background of glucocorticoid-induced repression, GR presence at specific IL1B-induced gene loci may reduce/protect from an otherwise more prevalent glucocorticoid-induced repression.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
