Expression of the NET family member <i>Zfp503</i> is regulated by hedgehog and BMP signaling in the limb
Bibliographic record
Abstract
The NET/Nlz family of zinc finger transcription factors contribute to aspects of developmental growth and patterning across evolutionarily diverse species. To date, however, these molecules remain largely uncharacterized in mouse and chick. We previously reported that limb bud expression of Zfp503, the mouse orthologue of zebrafish nlz2/znf503, is dependent on Gli3. Here, we show that Zfp503/Znf503 is expressed in a restricted pattern during mouse and chick embryogenesis, with particularly dynamic expression in the developing limbs, face, somites, and brain. We also add to our previous data on Gli3 regulation by showing that the anterior domain of Zfp503 expression in the mouse limb is responsive to genetic and nongenetic manipulation of hedgehog signaling. Finally, we demonstrate that posterior expression of Znf503 in the chick limb is responsive to bone morphogenetic protein (BMP) signaling, indicating that Zfp503/Znf503 may act at the nexus of multiple signaling pathways in development.

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.
