Characterization of <i>PAF‐AH Ib1</i> in NOD Mice
Bibliographic record
Abstract
We recently mapped Idd4 to a 5.2 cM interval on chromosome 11 with two subloci, Idd4.1 and Idd4.2, in nonobese diabetic (NOD) mice. Based on the localization of platelet-activating factor acetylhydrolase Ib1 (PAF-AHIb1) and the decreased activity of PAF-AH in type 1 diabetes (T1D) patients, we hypothesized that PAF-AHIb1 in Idd4.1 is a candidate gene. The PAF-AHIb1 gene in NOD mice was cloned and sequenced, and its expression and function were studied. No polymorphisms were detected in PAF-AHIb1 cDNA between NOD and B6 mice. The expression of PAF-AH Ib1 at the mRNA and protein levels was found to be similar in different tissues between NOD and B6 mice. PAF-AH activity does not differ in the pancreatic islets or spleen between NOD and B6 mice. Our findings suggest that PAF-AH Ib1 may not be a diabetes-susceptibility gene in the Idd4.1 sublocus.

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.
