Abstract
It was recently demonstrated that antiestrogens prevented prostate cancer (PRCA) in men. The source of estradiol (E2) that contributes to carcinogenesis, as well as the selected estrogen receptor (ER) signaling pathway, is unknown. To evaluate estrogen's effects in carcinogenesis, we developed a new model of PRCA utilizing testosterone and E2 to stimulate PRCA. To determine whether local in situ production of E2 affected incidence of PRCA, aromatase-knockout (ArKO) mice were evaluated. In contrast to the wild-type mice, ArKO mice had reduced incidences of PRCA, which implicates in situ production of E2 as an important determinant of PRCA. To determine whether E2-mediated responses were due to ER alpha or ER beta signaling, ER alpha-knockout (alphaERKO) or ERbeta-knockout (betaERKO) mice were used. Prostates from betaERKO mice underwent biochemical and histological carcinogenesis similar to wild-type mice, whereas prostates from alphaERKO mice remained free of pathology. These data suggest that effective prevention of carcinogenesis will require antagonism of ER alpha but not ER beta. This mouse model provides a means to examine genetic gain and loss of function and determine the efficacy of therapeutics on prostatic carcinogenesis.

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
