Abstract
Androgens have been postulated to be important modulators of adipose tissue metabolism and fat cell function. In the present study, we investigated the response of male and female mice retroperitoneal adipose tissue to the nonaromatizable androgen dihydrotestosterone (DHT). Adipose tissue samples were obtained in gonadectomized animals treated with vehicle (control group), or injected with 0.1 mg DHT 1, 3, 6, 12, 18, and 24 h prior to necropsy. Fourteen animals were pooled at each time point (total 196 animals). Transcripts that were significantly modulated were considered as androgen-responsive genes. Quantitative real-time RT-PCR was used to confirm results from the microarray analysis in a subset of 46 probe sets in male mice and 98 probe sets in female mice. Considering peak time vs. control, we confirmed 74.0 and 63.3% of the modulated genes by PCR in males and females, respectively. Four genes were significantly stimulated in a similar manner by DHT in both sexes, namely metallothionein 1, growth arrest and DNA-damage-inducible 45 gamma, cyclin-dependent kinase inhibitor 1A, and fk506-binding protein 5. All these genes appear to be involved in the regulation of adipocyte differentiation/proliferation and adipogenesis. In conclusion, this study, which evaluated the acute transcriptome response of adipose tissue to DHT in male and female mice, suggests that DHT consistently modulates genes involved in the regulation of adipogenesis in retroperitoneal adipose tissue of both male and female animals.

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 it
