Dynamin-dependent maintenance of epithelial integrity is essential for zebrafish epiboly
Bibliographic record
Abstract
Epiboly, the thinning and spreading of one tissue over another, is a widely employed morphogenetic movement that is essential for the development of many organisms. In the zebrafish embryo, epiboly describes the coordinated vegetal movement of the deep cells, enveloping layer (EVL) and yolk syncytial layer (YSL) to engulf the yolk cell. Recently, we showed that the large GTPase Dynamin plays a fundamental role in epiboly in the early zebrafish embryo. Because Dynamin plays a well-described role in vesicle scission during endocytosis, we predicted that Dynamin might regulate epiboly through participating in bulk removal of the yolk cell membrane ahead of the advancing margin, a proposed part of the epiboly motor. Unexpectedly, we found that Dynamin function was dispensable in the yolk cell and instead, it was required to maintain the epithelial integrity of the EVL during epiboly. Here, we present a model describing the maintenance of EVL integrity, which is required for the proper generation and transmission of tension during epiboly. Furthermore, we discuss the role of Dynamin-mediated regulation of ezrin-radixin-moesin (ERM) family proteins in the maintenance of epithelial integrity.

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.
