Expression of autophagy-related genes in the anterior silk gland of the silkworm (<i>Bombyx mori</i>) during metamorphosis
Bibliographic record
Abstract
Programmed cell death (PCD) is a genetically regulated process of cell elimination and is evolutionarily conserved in eukaryotes. Degeneration of larval tissues during metamorphosis in insects is a result of PCD triggered by ecdysteroids and autophagic process has been shown to be involved in the degeneration of silk gland of the silkworm ( Bombyx mori L., 1758). However, experimental evidence for the expression of autophagy marker genes remains insufficient. In this study, expression of the autophagy-related genes BmAtg5, BmAtg6, BmAtg8, and BmAtg12 was determined in the anterior silk glands of larvae and pupae during larval to pupal transformation by using reverse-transcription PCR, quantitative real-time PCR, and Western blot analyses. The results indicated that BmAtg5, BmAtg6, BmAtg8, and BmAtg12 had the highest expression levels on the 3rd day of the wandering stage or at the prepupal stage, and the time frame of the expression of these genes was coincident with the morphological characteristics of autophagy in the silk gland during the larval to pupal transformation. This study demonstrated that the autophagy-related genes are involved in the degeneration of the anterior silk gland of B. mori.

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.
