Abstract
While considerable information is available on the physiological effects of estrogen, much less is known about the regulation of estrogen receptor (ER) subtypes, particularly in non-mammalian vertebrates. Using goldfish as primary experimental model, we investigated sex- and tissue-specific homologous regulation of ER subtypes (ERalpha, ERbetaI, and ERbetaII) by estradiol in vivo, in the liver and gonads. Treatment with estradiol, significantly upregulated transcript levels for all three types of ERs (ERalpha, ERbetaI, and ERbetaII) in the goldfish ovary and testis. In the goldfish liver, treatment with estradiol significantly increased ERalpha, ERbetaI transcript levels without affecting ERbetaII. In all cases increased ER transcript level was correlated with increased ER protein level determined by Western blot analysis, although we are not able to distinguish between ER subtypes. The results provide strong support for the hypothesis that homologous regulation of ERs is tissue- and gender-specific, and may be a mechanism for estrogen-mediated regulation of reproduction in goldfish.

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
