Anatomic Modifications in the Enteric Nervous System of JF1 Mice with the Classic Piebald Mutation
Bibliographic record
Abstract
The Japanese Fancy Mouse 1 (JF1) has a characteristic coat color similar to a very old mutant, piebald. The mutation in JF1 and the classic piebald was previously thought to be the same recessive allele in the endothelin B receptor gene (Ednrb) according to the haplotype pattern, which is insufficient for this conclusion. In this study, we identified the same insertion of a retroposon-like element in intron 1 of the Ednrb gene in JF1 as in the classic piebald mutation by PCR. Further, we investigated whether the intestine shows neuronal intestinal malformations such as hypoganglionosis and immaturity of ganglion cells by histochemical staining. Though it has been assumed that the defect of neural crest-derived lineages is restricted to melanocytes in JF1, we found that the enteric innervation and neuronal density were impaired throughout the whole colon in JF1 mice.

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.
