Loss of zebrafish <i>dcst2</i> expression is not associated with muscle abnormalities
Bibliographic record
Abstract
Abstract In this study we examined if the gene encoding Dendritic Cell-specific Six Transmembrane domain containing protein 2 ( dcst2 ) plays a role in vertebrate muscle biology. Using the CRISPR/Cas9 mutagenic system we generated a 2 nucleotide deletion in exon 3 of the zebrafish ortholog dcst2 which resulted in a premature stop codon. Homozygous carriers of the mutation displayed reduced transcriptional expression of dcst2 suggesting that our mutation was indeed disrupting gene function. Mutant dcst2 zebrafish developed normally to adulthood and displayed no differences in motor function using a free-swim and swim tunnel assays. Furthermore, histological examination of muscle cells revealed no differences in slow-twitch or fast-twitch muscle cell cross-sectional area in our mutants. We did observe that dcst2 -/- zebrafish were slightly heavier in weight and males were infertile. The data collected here, suggest that dcst2 does not play a role in zebrafish muscle cell biology.

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.
