Modulation of Glucocorticoid Receptor Function and Expression in Adolescent Moderate Asthma
Bibliographic record
Abstract
BACKGROUND: Previous studies on adult asthmatics have shown that the disease is associated with alterations in glucocorticoid receptor (GR) function. OBJECTIVES: The aim of the present study was to examine GR functional properties in adolescent asthma of different severity. Therefore, we determined GR hormone binding parameters, e.g. the equilibrium dissociation constant (K(d)) and the number of binding sites (B(max)), as well as the level of receptor expression in mononuclear cells isolated from the peripheral blood of patients with mild/moderate persistent asthma. METHODS: The GR hormone binding activity was assessed by whole-cell binding assay, while receptor expression was evaluated by quantitative Western blotting. RESULTS: In peripheral blood mononuclear cells (PBMCs) of patients suffering from moderate asthma, the GR displayed higher K(d) and B(max) values (78.0 +/- 19.5 nM and 11,715 +/- 1,952 sites/cell, respectively; n = 17) in comparison to healthy subjects (23.8 +/- 7.7 nM and 6,124 +/- 1,369 sites/cell; n = 12) and mild asthmatics (22.4 +/- 8.0 nM and 4,840 +/- 776 sites/cell; n = 11). However, the GR protein level in PBMCs was found to be similar in the three study groups. CONCLUSION: The results provide data on GR expression and its functional status in inflammatory cells of pediatric asthmatic patients. In moderate asthma, functional characteristics of GR are altered, though the significance of these findings remains to be clarified.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
