Glucocorticoid receptor-mediated expression of kallikrein 10 in human breast cancer cell lines
Bibliographic record
Abstract
Using the breast cell lines MCF-10A, MDA-MB-468 and T-47D, we investigated the role of various glucocorticoids in regulating human kallikrein 10 expression. We found that increased concentrations of glucocorticoids decreased KLK10 expression in MCF-10A and increased KLK10 expression in MDA-MB-468 and T-47D cells. Stimulation of the cell lines using other steroid hormones did not yield any difference in KLK10 expression in MCF-10A and MDA-MB-468 cells, suggesting that regulation of KLK10 occurs primarily through glucocorticoids. However, T-47D cells expressed higher levels of KLK10 upon dihydrotestosterone stimulation. Blocking the glucocorticoid receptor (GR) demonstrated that the mechanisms of induction and repression are different in the three cell lines studied. Taken together, our results suggest an alternative mode of KLK10 regulation - by glucocorticoids via GR-dependent mechanisms.

How this classification was reachedexpand
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.
