Estrogen Binding in Mammary Tissue of C3H Mice With or Without the Mouse Mammary Tumor Virus
Bibliographic record
Abstract
Substrains of C3H mice, with and without the milk-transmitted form of the mouse mammary tumor virus (MMTV)1, were compared to determine if the presence of MMTV altered estrogen action. Uterine weight response to oral diethylstilbestrol was the same for both substrains, (MMTV+ and MMTV-). The concentration of high-affinity estrogen binding sites ("receptors") in lactating mammary tissue did not differ significantly for MMTV+ versus MMTV- mice; the affinity of the estradiol-receptor interaction appeared higher, however, in cytosol from MMTV- mice. Sucrose density gradient analysis revealed no significant differences in sedimentation properties of cytosol receptor from the two substrains.

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.
