Ontogenic Expression of Estrogen Receptor-α in Female Rat Corneas
Bibliographic record
Abstract
PURPOSE: To investigate ontogenic expression of estrogen receptor (ER)-alpha in female rat corneas, as part of basic studies to elucidate the mechanism of estrogenic effects on the corneas. METHODS: The expression and localization of ERalpha were determined using quantitative reverse transcribed-polymerase chain reaction methodology and immunohistochemistry in the corneas of female rats on day 14 of gestation and postnatal days (PNDs) 0, 21, and 60. RESULTS: Quantitative analysis of ERalpha mRNA revealed that ERalpha gene expression increased approximately 4 times on PND 21 and about 10 times on PND 60, as compared with expression levels detected on PND 0. Immunohistochemical analysis revealed that expression of ERalpha protein was evident only in nuclei of the corneal epithelial cells from PND 21 onward. CONCLUSION: Ontogenic expression of ERalpha occurred in female rat corneas.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
