Perturbed thyroid morphology and transient hypothyroidism symptoms in <i>Hoxa5</i> mutant mice
Bibliographic record
Abstract
The Hox family of transcriptional regulators has been extensively studied for their role in axial and appendicular patterning. Genetic analyses have also unveiled Hox gene function in organogenesis and postnatal development. A phenotypical survey of the Hoxa5(-/-) mutant mice shows that the surviving mutants display symptoms of hypothyroidism, including transient growth retardation, and delayed eye opening and ear elevation. Thyroid gland morphogenesis initiates normally, but follicle formation and thyroglobulin processing are abnormal at late gestation. The expression of several molecular markers essential for thyroid gland formation and function, namely Nkx2.1, Pax8, and Titf2, is affected in the developing thyroid gland of Hoxa5(-/-) mutants. As a consequence, the expression of thyroid effector genes, including the thyroglobulin and thyroperoxidase genes, is perturbed. Our characterization reveals that the loss of Hoxa5 function transiently affects thyroid development in a non-cell autonomous manner.

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.
